edoras one Modeler Guide

1. Modeler Overview

The modeler dashboard can be accessed by authorized users through the dashboard menu and is used to create and deploy workflow models for use within edoras one.

Before we look at the details of the modeler dashboard it will help to understand how models are related to the user dashboard.

Models are created edited in the modeler dashboard, and as long as they are only edited they are not visible in the user dashboard. When models are deployed, corresponding definitions are created. These definitions can be used in the user dashboard to create work objects of the new type.

1.1. App Models

An edoras one App model contains a collection of different models that combine to define a specific workflow within edoras one.

An app model can be created and then different models can be added and linked together as required. When the workflow is ready, it can be deployed to create the corresponding definitions which are used to execute the workflow, and it can then be tested.

App models can be transferred between different edoras one installations using the Export and Import actions.

1.2. edoras vis

edoras vis is a modeler with focus on modeling BPMN 2.0-compliant processes, edoras one compliant forms and CMMN 1.0-compliant case models.

2. Model types

2.1. Form model

A form model defines a form that can be used by other workflow models to interact with the user. Each form contains a number of form fields arranged in a given layout. The fields in a form may contain predefined content, or may be bound to work object values at runtime, for example to allow the name and description of a document to be displayed and perhaps changed.

Typically two types of forms are used: init forms are used to initialize new work objects, and work forms are used to edit existing work objects.

Form models can be quickly checked by hovering over the form name, previewed within edoras one using the Preview view or edited in the edoras vis modeler using the Design action. It is also possible to download the XML form definition using the Download action.

2.2. Task model

A task model is used to define a new type of user task. The init and work forms for a task are used to create and edit the task contents, and are set using the Browse view. The default candidate groups used for sharing can also be set, and the actions that will be allowed on this type of task can also be selected.

2.3. Document model

A document model is used to define a new type of document. As in the task model, the Browse view allows the init and work forms to be selected, as well as setting the candidate groups and allowed actions. Moreover, the placeholders can also be defined in this view.

2.3.1. Skeleton documents

A skeleton document can be set using the Upload skeleton action. If a skeleton document is provided then whenever a new document of this type is created it will be initialized with its own copy of the skeleton document. Placeholders can also be defined to insert dynamic text into the document copy.

2.3.2. Placeholder expressions

Document models can define placeholder expressions that can be used to insert dynamic values into documents.

A placeholder definition consists of a key (which will be referenced from the document) and an expression that will be evaluated to give the corresponding value:

The expression will be applied at the time that the placeholders are updated, i.e. either when the document is first created from the document model or when the Update placeholders action is used subsequently.

2.3.3. Referencing placeholders from a Microsoft Word document

In a Microsoft word document, placeholders may be referenced by inserting a form field into the document with a Bookmark name that corresponds to the placeholder key:

2.3.4. Referencing placeholders from an Adobe PDF document

In a PDF document, placeholders may be referenced by inserting a form field into the document with a name that corresponds to the placeholder key:

Note	A suitable PDF editing tool is required to create PDF documents with form fields.

2.3.5. Microsoft Word Mailing support

Microsoft Word documents support mailings functionality. Mailings fields can be replaced in a similar way as placeholders with document variable values. The fields have to be encapsulated into TableStart/End tags (Mailings regions support). variableName tag is replaced by variable value on update placeholders action.

Note	To read more about merge mails follow the links: http://www.aspose.com/docs/display/wordsnet/Mail+Merge+with+Regions+Explained and http://support.microsoft.com/kb/212034.

2.4. Process model

A process model allows a full BPMN 2.0 process execution model to be defined. As for form models a process model can be previewed or edited in the modeler using the Design action, and the process definition XML can also be downloaded. Process models allow modeler to specify process init and work forms.

2.5. Case model

A case model is used define a new type of case. A case serves as a container for other work objects and can be used to store shared context information for a given workflow.

When a new case is created, it is possible to start processes, create tasks or create documents and link these to the case automatically. It is also possible to define which processes, tasks and documents can be created. This behaviour is defined using the Browse view. This view allows the init and work forms to be selected, as well as setting the candidate groups and allowed actions.

2.6. Mail model

A mail model provides a template for mails that can be sent by a given workflow. The mail model contains the templates for mail subject and header, both of which can use edoras one backend expressions to fill in the template with dynamic information at the time that the mail is sent.

3. Working with models

3.1. Accessing the modeler dashboard

All users that are part of the modeler group will be able to access the modeler dashboard.

3.2. Importing App models

An App model can be imported into the system by creating a new App through the user interface, and then using the Import action within the app to upload and import a Zip file containing the models to be imported.

When models are imported, the model will be checked to see whether it is already present on the system. If it is not present, then it will be created in the current App. If it is already present within the current App then it will be updated from the import file. If it is already present but as part of a different App then an error will be shown.

If a new model is created from scratch it is assigned an unchangeable ID which is used to track the model across all systems where the model is installed, and it is this ID which is used to establish the relationship between the models on the system and the models in the import file.

If the Import as duplicate option is selected when an App is imported the models in the imported App will not be checked against the models already present. New models will be created that are unconnected with the originals. This can be useful for creating a completely new App, using an existing App as a starting point.

3.3. Models state

Models have a state which changes as the models are edited and deployed. The available states are:

Table 1. Model states
State	Applies to	Description
active	Models	No pending changes. The model is currently deployed on the system.
inactive	Models except App model	No pending changes. The model has been deactivated on the system.
pending	Models	The model contains changes that have not yet been deployed.
pending inactive	Models except App model	The model will be deactivated on the system when it it next deployed.

3.4. Deploying an App model

When an App model is deployed, the models within that App model will be checked for consistency. If a model has been deactivated but there are still references from other active models then it will not be possible to deploy the App model. If the models are consistent then they will be deployed and corresponding definitions will be created. The users of the system will then be able to access the new workflow in the user dashboard.

Note that work objects and processes may already exist that were created using older versions of the model. These will not automatically be updated to use the new definitions: they will continue to use the definitions that were valid when they were created and will therefore not behave any differently after the new deployment.

3.5. Moving models between App models

All of the basic model types can be moved to another App as long as there are no outstanding references within the App model that it is being moved from.

3.6. Duplicating App models

All basic model types can also be duplicated, making an exact copy with a new name. This can be very useful when several small variations of a complex model are required.

Models may also be shared with different groups. By default all new models are shared with the modeler group, but in some circumstances it may be required for particular users to work on a particular set of models.

3.8. The System App

The administrator will also be able to see the System app in the modeler dashboard in addition to the App models that can be seen by normal modeler users. This App model contains a number of models that are required by the edoras one application and should normally not be changed.

4. Actions

Certain models are used to create user work items (e.g. Case, Task, Document). When created, the work item action toolbar (on the right hand side) will contain the actions that can be performed on the work item.

Which actions are available to the user depends on a number of factors:

the actions allowed by the model itself
the state of the work item
the user’s permissions

Some constraints are defined by edoras one itself and cannot be changed, but the model plays a large role in defining the available actions, and this should be considered carefully when designing a workflow.

To change the allowed actions, select the Browse view and add or remove actions as required in the Allowed Actions field:

Table 2. Actions
Action	Case	Task	Document	Description
Activate	Yes	Yes	Yes	Re-activate an archived work item
Archive	Yes*	No	Yes	Archived and active work item.
Assign	Yes	Yes	Yes	Change the work item’s owner / responsible
Create variables	Yes	Yes	Yes	Allow new variables to be created in the work item admin view
Download	No	No	Yes	Download the work item content
Download Pdf	No	No	Yes	Download the document in pdf format
Edit document	No	No	Yes	Edit the document
Move	No	No	Yes	Move the work item to another case
Preview	No	Yes	No	Show a work item preview
Share	Yes	Yes	Yes	Share the work item with specific groups
Start process	Yes	No	No	Start a new process instance
Update placeholders	No	No	Yes	Upload a new document
Upload document	No	No	Yes	Upload a new document

*There are three possibilities to archive cases which are displayed in the following table:

Table 3. Archive options for cases
Option Name	Description
Archive only if there are no active children	If case contains active processes, tasks or documents archive action returns an error.
Archive only if there are only active documents	If case contains active processes or tasks archive action returns an error. Active documents are archived automatically.
Archive the case and all children	Active processes and tasks are interrupted and it is not possible to activate them again. Active documents are archived.

5. Form palette

This section describes the elements available in the form palette of edoras one. Each modelling element and it’s corresponding attributes are described in detail below.

5.1. Concepts

This section describes the form concepts in edoras one. It starts with a description of how the layout of forms and fields works in edoras one. Then it describes how a form and its fields are bound to the data model.

5.1.1. Form layout

A form is a graphical layout of fields that may be bound to a data model to allow this data model to be displayed to the user. The fields are arranged in rows.

Figure 1. Form layout

Each row is made up of exactly twelve slots. All slots are equal in size, so the width of a slot is one twelfth the width of the whole form. A field can occupy exactly all slots or it can occupy only a part of the slots. With this it is possible to place more than one field in a row.

Figure 2. Form layout with slots

Not every slot needs to be occupied by a field. It is allowed that single slots of a row are empty. These empty slots can be at the beginning, in the middle, or at the end of a row.

Figure 3. Form layout with empty slots

5.1.2. Field layout

A field is made up of several parts (all but the widget part are optional):

widget: The widget visualizes the data model. Most widgets are interactive and let the user change the data model, however some widgets are read-only. There are widgets to manipulate strings, numbers, dates, rich text, selections, and many others. The widget is located in the center of the field, all other parts are arranged around the widget. The field configuration defines the concrete positioning of the field parts.
Label: The label tells the user to which part of the data model the widget is bound. The label is located on the left side or on top of the widget (depends on the field configuration).
Required indicator: The required indicator is displayed for required fields. Required means that the widget cannot be empty. The required indicator is located on the right side of the widget.
Description: The description gives additional information to the user. This can be formatting instructions or further description about how the App uses the entered value. The description is located on the bottom of the widget.

Figure 4. Field layout

5.1.3. Field alignment

To enhance the readability of a form, the field parts of all fields are aligned among themselves: the labels are aligned, the widgets and descriptions are aligned, the required indicators are aligned.

The alignment is performed per slot. All fields that start in the same slot build a field group. Inside such a field group edoras one looks for the widest label which becomes the dominating label for that slot. All labels in the field group are then enlarged to the same width of the dominating label. This is done by adding empty space between the label and the widget. This ensures that all widgets and descriptions of a field group start in one line and all.

Figure 5. Field alignment

The only exception is with fields that have top label position. For these fields the label, the widget and the description all start at the beginning of the slot.

Figure 6. Field alignment with top label position

5.1.4. Binding

Binding is the process to connect the form fields to the data model. The binding in edoras one is always two-way. When the user changes the form fields then those changes are immediately propagated to the data model. On the other side changes in the data model are immediately propagated back to the form fields.

A binding expression defines to which part of the data model the form field is connected. The binding expression has to be a writable frontend expression, e.g. {{foo}}, {{case.bar}}.

There are some reserved expressions which can not be used as they are used internally to save some work item information. They are:

id
definitionId
definition
type
state
creationTime
updateTime
currentUser

Moreover the expressions referring to the hierarchy (e.g. root, parent) can be only be used in order to bind nested widgets like subforms.

5.2. Common attributes

There are several attributes that are available for all form widgets. These common attributes define the rendering and the layout of the form field, as well as the part of the data model to which the form field is bound.

Attribute name	Description
Label	The label is a single word or term that describes the purpose of the form widget. When the form is rendered, the label is located either on the left side or on top of the widget (depends on the value of the Label position attribute). Typical labels are: First name, Last name, Sex, Address, ZIP code, City. Labels can be localized. See Localization to learn how to localize your Apps.
Label position	The label position relative to the widget, can be either Left or Top.
Value	The value connects the form field to the data model. As such the value decides which part of the data model the form field visualizes and which part of the data model is updated when the user interacts with the widget. See Binding to learn how binding in edoras one works.
Default value	The default value is the value that is applied when the data model is undefined, i.e. not yet initialized. The default value can be expressed as a static value or as a frontend expression. Typical default values are: Support (= string), false (= boolean), 42 (= number), Comment from {{role}} (= frontend expression). See Frontend expressions to learn the frontend expression syntax.
Description	The description is a whole sentence that describes the purpose of the form widget in more detail. When the form is rendered, the description is located below the widget. A typical description is: The ZIP file format is ##, e.g 4143. The ZIP is used to lookup the city. Descriptions can be localized. See Localization to learn how to localize your Apps.
Documentation	Intended for documenting details about specific widget to explain concepts of its use for future reference.
Visible	The visible flag decides if the form field is shown or hidden. If true, the form field is shown, if false the form field is hidden. The visible flag is a runtime value which means you can configure a frontend expression for it. A typical frontend expression for the visible flag is: {{case.showDeliveryAddress}} See Frontend expressions to learn the frontend expression syntax.
Editable	The editable flag decides if the form widget is editable or read-only. If true, the user can manipulate the form widget to change the data model, if false the user is not able to change the data model. The editable flag is a runtime value which means you can configure a frontend expression for it. A typical frontend expression for the editable flag is: {{case.step1Completed}} See Frontend expressions to learn the frontend expression syntax.
Style class	The style class allows to add additional CSS styles to the form field.

5.3. Validation attributes

A validation method checks if a widget contains valid data, if not edoras one displays an error message that instructs the user how to fix his input. edoras one supports many different validation methods, not all are available for all form widgets.

Note	Validation is only done if the user is able to fix a potential validation error. This is not the case for hidden and read-only form fields, so such fields are not validated.

The following table lists the supported validation methods.

Attribute name	Description
Required	The required flag defines if a form field can be empty or not. If true then the form field is not allowed to be empty, if false the form field might be empty. A typical sample where the required flag is set to true is a name field that is mandatory. The following form widgets support the required flag: text, text area, rich text area, password, number, date, checkbox, autocomplete, select, radio buttons.
Minimum length	The minimum length validation ensures that the text input is longer than a minimum length. A typical sample is a password that has to be at least 4 characters long. The following form widgets support the minimum length validation: text, text area, rich text area, password. The Minimum length error message attribute holds the error message that is displayed when the text input is less than the configured number of characters.
Maximum length	The maximum length validation ensures that the text input has a smaller than a maximum length. A typical sample is a password that has to be at most 8 characters long. The following form widgets support the minimum length validation: text, text area, rich text area, password. The Maximum length error message attribute holds the error message that is displayed when the text input is bigger than the configured number of characters.
Regular expression	The regular expression validation ensures that the text input matches a regular expression. See http://www.w3schools.com/jsref/jsref_obj_regexp.asp for more information on the supported regular expression syntax. Regular expression can be become quite complex and difficult to understand. http://www.regular-expressions.info/javascriptexample.html provides a good way to test your regular expressions. A typical sample is the number of a credit card which matches: ^4[0-9]{11,12}(?:[0-9]{3})?$. The following form widgets support the regular expression validation: text, text area, rich text area, password. The Regular expression error message attribute holds the error message that is displayed when the text input does not match the regular expression.

The maximum number supported is 9007199254740991.
Minimum date	The minimum date validation ensures that the date input is equals to or after a minimum date. The minimum date can be a fixed date, today, or a day relative to today. A typical sample is an delivery date field which has to be equals to or after today. The date form widget supports the minimum date validation. The Minimum date error message attribute holds the error message that is displayed when the date input is before the configured minimum date.
Maximum date	The maximum date validation ensures that the date input is equals to or before a maximum date. The maximum date can be a fixed date, today, or a day relative to today. A typical sample is a birthday field which has to be equals to or before today. The date form widget supports the maximum date validation. The Maximum date error message attribute holds the error message that is displayed when the date input is after the configured maximum.
Invalid selection error message	This validation displays an error message when the selection input is not available anymore. The autocomplete and the select widgets support the invalid selection validation. Both form widgets look up if the selection is in the available options to check if the selection is valid or not.
Minimum number of elements	The minimum number of elements validation ensures that the input contains at least a certain number of elements. A typical sample is an order which has to contain at least one order position. The subform widget and the autocomplete widget with multi-selection supports the minimum number of elements validation. The Minimum number of elements error message attribute holds the error message that is displayed when the input contains less than the configured number of elements.
Maximum number of elements	The maximum number of elements validation ensures that the input contains at most a certain number of elements. A typical sample is a wish list which can hold at most ten wishes. The subform widget and the autocomplete widget with multi-selection supports the maximum number of elements validation. The Maximum number of elements error message attribute holds the error message that is displayed when the input contains more than the configured number of entries.

5.5. Select form widgets

The select form widgets allow the user to select one or more options from a potential large set of options. The available options are presented in a list from which the user can select one or more options with help of the keyboard and the mouse.

Some select form widget support the filtering of the available options. When the user starts typing then only the options that match the typed text are presented as available options. This makes it easy to locate a specific option in a large set of options.

The select form widgets are very powerful form widgets. To support different selection requirements edoras one provides different variants of select form widgets. The following list explains these variants:

Selection	Options	Description
Single	Boolean true/false	Used to select a simple yes/no option. When the checkbox is ticked then true is stored in the data model, otherwise false is stored in the data model.
Single	Static options	Used to select a single option from a static list of options. At design time the modeler configures for each option a name and a value. The name is displayed to the user whereas the value is stored in the data model. In the radio button form widget all options are always visible. With this the user can always see all possible option, on the other side this uses a lot of form real estate and is therefore suited only it there are few options.
Single or multiple	JSON options	Used to select one or more options from a dynamic list of options. The dynamic list of options is built at runtime by calling a custom REST endpoint that the modeler has configured. Either a single attribute of the option or the complete option is stored in the data model.
Single or multiple	edoras one work items	Used to select one or more work items from a dynamic list of work items. The dynamic list of work items is built at runtime by calling edoras one with a query that the modeler has configured. Either the work item id or the complete work item is stored in the data model.
Single or multiple	Static options	Used to select one or more options from a static list of options. At design time the modeler configures for each option a name and a value. The name is displayed to the user whereas the value is stored in the data model.
Single	Static options	Used to select a single option from a static list of options. At design time the modeler configures for each option a name and a value. The name is displayed to the user whereas the value is stored in the data model. The select static form widget is not able to filter the possible options. To select an option the user first has to navigate to the desired option by scrolling in the option list. Therefore this form widget is not a good choice if there is a large number of options.

The select static form widget is not able to filter the possible options. To select an option the user first has to navigate to the desired option by scrolling in the option list. Therefore this form widget is not a good choice if there is a large number of options.

Note

The functionality of the Radio button group, the Autocomplete static and the Select static form widgets is similar. The only difference is the look and feel. The Radio button group form widget always shows all options with the drawback that this requires a lot of form real estate. The Autocomplete static and the Select static form widgets need little form real estate with the drawback that the user first has to focus the field and open a popup to see the available options.

Note

the functionality of the REST autocomplete select and the Autocomplete select form widgets is similar. The only difference is that the REST autocomplete select form widget uses a custom REST endpoint to load the possible options (which can be of any format) whereas the Autocomplete select form widget uses edoras one to load the possible work items.

Validation

The REST autocomplete select form widget supports the following validations:

Required.
Invalid selection.
Minimum number of elements.
Maximum number of elements.

See Validation attributes to learn more about validation.

Query URL

Used to load the available options that are presented to the user from a URL.

The query URL attribute can be expressed as a static value or as a frontend expression. See Frontend expressions to learn the frontend expression syntax.

The autocomplete form widget expects the options to be returned as list of JSON objects, e.g.

[ {
  "id" : "GEAR-a65c4a12-20b4-45d8-bb09-2105be7f0d1f",
  "title" : "edoras one Modeler",
  "value" : "GEAR-a65c4a12-20b4-45d8-bb09-2105be7f0d1f"
}, {
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
} ]

The user typed text is added as a URL parameter to the query URL.

https://one.edorasware.com/rest/one-groups?typedText=edoras

Usually the REST endpoint uses the typed text to filter the available options. This way the user sees only the options that match the already typed text and can easily locate single options in a large set of options.

Note	The options are filtered in the REST endpoint and not in the autocomplete form widget. If the REST endpoint does not do the filtering then independent of the typed text the autocomplete form widget always presents the same options to the user.

Note

Referencing external resources may have problems due to SSL (https) or CORS security browser limitations. To solve CORS security, the resource server must send appropriate response headers. Another option is using a proxy to receive the right response headers from any url e.g .:https://cors-anywhere.herokuapp.com. To solve SSL if edoras one is being executed over https, the url of the external resource should also have the https protocol.

Lookup URL

Used for two things:

first: to load the complete information of the selected options (only if they are stored in serialized form in the data model)
second: to validate if the selected options are still available, see Validation attributes to learn more about this validation

In both cases the serialized option is appended to the lookup URL, e.g.

https://one.edorasware.com/rest/one-groups/GEAR-a65c4a12-20b4-45d8-bb09-2105be7f0d1f

The option is serialized with help of the Serialization. So the Lookup URL and the Serialization attribute have to play together.

Serialization

Used to select the attribute in the JSON option that is stored in the data model.

The prefix to select an attribute from the JSON option is item.

So if the JSON option looks like

{
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
}

then a Serialization of item.id results in GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac being stored in the data model.

Note

Please note that the Serialization, the Query URL, and the Lookup URL attributes have to play together. The Serialization converts the JSON options returned by the Query URL REST endpoint into strings which then are stored in the data model. And the Lookup URL REST endpoint does the opposite: it takes the strings stored in the data model and converts them back into JSON options.

Format

Used to compose a user friendly string from the JSON option.

The prefix to select an attribute from the JSON option is item. Literals have to be enclosed in quotes, attributes and literals can be concatenated with +.

So if the JSON option looks like

{
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
}

then a format of Group: {{item.title}} results in Group: edoras one User being presented to the user for this JSON option.

Navigation URL

Used to set a link icon to the left of each option in the list and each selected option. The Navigation URL defines the URL to navigate to when the user clicks a link icon.

The navigation URL attribute can be expressed as a static value or as a frontend expression. See Frontend expressions to learn the frontend expression syntax.

The prefix to select an attribute from the JSON option is $item.

So if the JSON option looks like

{
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
}

then a navigation URL of /GRP/{{$item.id}}/browse results in /GRP/GEAR-3456061f-4892-4ef4-b234-69217201cd09/browse being invoked when the user clicks the link icon.

Target

Used to define the tab where the linked option is loaded.

Possible values are:

_blank ⇒ Load in a new tab
_self ⇒ Load in the same tab as it was clicked
tabname ⇒ Load in a named tab, if there is no tab with that name then a new tab is created with that name

Multi selection

False if only one option can be selected, true if multiple options can be selected.

If true then the selected options are stored as a list in the data model.

Preselect all

If true, ALL objects returned by the REST endpoint are automatically selected. This only works, if multi selection is turned on too.

Attribute name

Description

Common

See Common attributes to learn more about the common attributes.

The REST list form widget does not support the Value, the Default value and the Editable attribute, as these do not make sense for read only widgets.

Query URL

Used to load the items that are presented to the user from a URL.

The query URL attribute can be expressed as a static value or as a frontend expression. See Frontend expressions to learn the frontend expression syntax.

The list form widget expects the items to be returned as list of JSON objects, e.g.

----
[ {
  "id" : "GEAR-a65c4a12-20b4-45d8-bb09-2105be7f0d1f",
  "title" : "edoras one Modeler",
  "value" : "GEAR-a65c4a12-20b4-45d8-bb09-2105be7f0d1f"
}, {
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
} ]
----

Note

List title

Used to define the title that is shown in the header of the list.

The list title attribute can be expressed as a static value or as a frontend expression. See Frontend expressions to learn the frontend expression syntax.

Format

Used to compose a user friendly string from the JSON item.

The prefix to select an attribute from the JSON item is item. Literals have to be enclosed in quotes, attributes and literals can be concatenated with +.

So if the JSON item looks like

{
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
}

then a format of Group: {{item.title}} results in Group: edoras one User being presented to the user for this JSON item.

Minimum number of visible items

Used to define the minimum height of the list.

The list height is forced to a height that can show at least a certain number of items. If the concrete list has less items then the missing space is filled with empty items. For example if there are 5 items to show and the minimum height is 10 then the list height is forced to a height that can show 10 items.

formComponentListRestRuntimeMinimumHeight

Maximum number of visible items

Used to define the maximum height of the list.

The list height is forced to a height that can show at most a certain number of items. If the concrete list has more items then the list shows a scroll with which the user can scroll in the list. For example if there are 15 items to show and the minimum height is 10 then the list height is forced to a height that can show 10 items.

Navigation URL

Used to define the URL to navigate to when the user clicks an item in the list.

The navigation URL attribute can be expressed as a static value or as a frontend expression. See Frontend expressions to learn the frontend expression syntax.

The prefix to select an attribute from the JSON option is $item.

So if the JSON item looks like

{
  "id" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac",
  "title" : "edoras one User",
  "value" : "GEAR-c641f3bb-876e-45f4-9550-ef95ef5a2fac"
}

then a navigation URL of /GRP/{{$item.id}}/browse results in /GRP/GEAR-3456061f-4892-4ef4-b234-69217201cd09/browse being invoked when the user clicks the item in the list.

Target

Used to define the tab where the linked item is loaded.

Possible values are:

_blank ⇒ Load in a new tab
_self ⇒ Load in the same tab as it was clicked
tabname ⇒ Load in a named tab, if there is no tab with that name then a new tab is created with that name

5.8. Nesting form widgets

The nesting form widgets allow to nest widgets.

The data model of a nested form is usually stored in a nested data context. If configured that way the forms and the data model nest in a corresponding way: A field in a nested form then becomes a attribute in the nested data context.

Nested forms can be repeated. This way it is possible to define lists in the data model.

Usually nested forms are rendered in a way that the user can clearly see that the form fields belong to a nested form. But if desired nested forms can be rendered in a transparent way. The user can then not tell if a field comes from the main form or from a nested form.

Form widget

Description

Used to nest forms of a single type.

Used to nest forms of multiple types.

5.8.1. Single-type subform attributes

Attribute

Description

Form reference

Used to define the form that is rendered in place of the subform.

The editor for this attribute allows to pick an existing form or to create a new one.

Element name

Used to define the text for the add button.

Common

See Common attributes to learn more about the common attributes.

The Value attribute is used to define the nested data context. This means if the Value is set to foo then all data inside the subform is stored in the foo attribute of the data model.

This widget does not support the Label position, the Default value, and the Description attribute, as these do not make sense for nesting widgets.

Validation

This widget supports the minimum number of children and the maximum number of children validation.

See Validation attributes to learn more about validation.

Multiple elements

Used to define if the user can repeat the form or not.

If true, additional buttons are rendered to let the user add new forms and remove existing ones.

formComponentSingleTypeSubformRuntimeRepeating

Show border

Used to define if the form inside the subform form widget is rendered nested or not.

If true the form is rendered in a nested way and the user can clearly see that this is a nested form. If false the form is rendered in a transparent way and the user cannot distinguish if a field comes form the main form or from the nested form.

formComponentSingleTypeSubformRuntimeTransparent

Show add/remove buttons

If the subform can hold multiple elements, this attribute specifies whether the add/remove buttons should be shown and thus allowing the user to create new elements or to remove existing elements. This can also be done using a dynamic expression.

Collapsible

If true, the subform can be collapsed/expanded by clicking on an arrow ▲/▼.

Collapsed

If true, the subform will appear collapsed by default.

It supports FE expression by writing it in "Collapsed(RT)" field. Using FE expression, if the value of the expression changes, it will be applied to the subform, that is, if it becomes true, the subform will be collapsed and vice versa.

5.8.2. Multi-type subform attributes

Attribute

Description

Form references

Used to define the forms that are rendered in place of the subform.

The editor to define the form references asks for a discriminator value, the form reference and display name. The discriminator value identifies the form reference and hence the form to be used inside the data model. The display name is used to define the text for the add button.

The value stored in the discriminator attribute decides which form is used to display the data in the sub data context.

Common

See Common attributes to learn more about the common attributes.

The Value attribute is used to define the nested data context. This means if the Value is set to foo then all data inside the subform is stored in the foo attribute of the data model.

This widget does not support the Label position, the Default value, and the Description attribute, as these do not make sense for nesting widgets.

Validation

This widget supports the minimum number of children and the maximum number of children validation.

See Validation attributes to learn more about validation.

6. Process Palette

This section describes the elements available in the process modelling palette of edoras one. Each modeling element and it’s corresponding attributes are described in detail below. Since edoras one is based on BPMN 2.0 huge parts of the modelling capabilities come from there. Currently, edoras one does not support the full BPMN 2.0 standard for execution. The process palette contains only the BPMN2.0 elements that are currently supported by the engine. Besides the BPMN 2.0 standard elements, edoras one provides some dedicated process activities that can be used within the processes. These edoras one specific activities are dedicated implementations of BPMN 2.0s generic service task. They are implemented using the custom extensions hook of BPMN 2.0 so if you import a process model to another system that supports BPMN 2.0 these activities are considered as generic service tasks.

There are several attributes, that are available for all modelling elements:

Table 4. Common attributes
Attribute Name	Description
Name	The name of the element, displayed on the diagram. This attribute is not equal to the id of the element.
Documentation	Use this attribute to add any documentation / description to the element. The content of the element can not be displayed on the model graphics, but is exported to the BPMN 2.0 XML.
Custom Properties	Define arbitrary properties as key value pairs. The attribute is exported to the BPMN 2.0 XML and can be accessed at runtime.
Background Colour	Specify the background colour of the element in the diagram.
Border Colour	Specify the border colour of the element in the diagram.
LoopType	Selection of the loop type. See Multi Instance to know more about loops.

There are several attributes, that are available to customize the font format of all modelling elements in the diagram. If the attributes are set at process level, all the components of the process will contain these attributes by default:

Table 5. Text format attributes
Attribute Name	Description
Font size	Specify the font size of the element in the diagram.
Font weight	Specify the font weight of the element in the diagram.
Font style	Specify the font style of the element in the diagram.
Font Color	Specify the font color of the element in the diagram.

These attributes can also be modified by the shortcut with a "T" icon placed in the left-bottom corner of the components. Clicking on this brings up a text format dialog where the formatting can be changed as required. The dialog includes a button to remove the style format and goes back to the default format.

Moreover the process can contain attributes associated to the whole process. In order to set them click in the design area without selecting any element.

Table 6. Process attributes
Attribute Name	Description
Init form ref	The reference to a form which will be rendered before the process starts by the 'Start process' action.
Label expression	Specify a label expression for tasks within this process if you want something else being used as the name property.
Custom Properties	Define arbitrary properties as key value pairs. The cutom properties will be saved to a process level.
Is executable	If is set to false the deployment will ignore the process. Once is set to true and the process deployed
Text format attributes	See the table above. If the text format attributes are set at process level, all the components of the process will be created with the format set.
