Support Binding to Form Files

Similar to how I can configure the binding of a DMN file through the properties panel I want to be able to configure a binding of a form file. This involves both changes in the Camunda Modeler and in the form-js library.

Sketch

Bindings

• deployment
• latest
• version

• versionTag is out of scope for now

New Start Event / User Task Properties

• camunda:formRef (maps to id property of the form)
• camunda:formRefBinding (deployment, latest or version)
• camunda:formRefVersion (maps to an internal version property set by the engine)

New Form Properties

• id (maps to camunda:formRef property of a start event / user task)

Example

Form

{
  id: 'formId',
  type: 'default',
  components: [
    ...
  ]
}

id will be set on the root of the form JSON.

BPMN

<bpmn:userTask
  id="Activity_1"
  camunda:formRef="formId"
  camunda:formRefBinding="version"
  camunda:formRefVersion="7">
</bpmn:userTask>

or

<bpmn:userTask
  id="Activity_1"
  camunda:formRef="formId"
  camunda:formRefBinding="latest">
</bpmn:userTask>

or

<bpmn:userTask
  id="Activity_1"
  camunda:formRef="formId"
  camunda:formRefBinding="deployment">
</bpmn:userTask>

These properties will be set through the properties panel. Therefore, the root must be selectable/form fields must be deselectable.

FYI: the specification and backend implementation on platform side is done, so this is ready for implementation

Feature is merged and waiting to be released and integrated into Camunda Modeler.
