Support `bindingType` for called processes/decisions/forms

[jfriedenstab]

Problem you would like to solve

As a Camunda 8 user, when I design a BPMN process, I'd like to be able to choose between the binding types latest and deployment for called processes, called decisions and linked forms. I would also like to understand the differences between them so I can pick the right one for my use case.

Proposed solution

• [x] Add a new dropdown "Binding" with the options latest and deployment to the properties panel:
  • [x] to the "Called element" section for a call activity
  • [x] to the "Called decision" section for a business rule task (below "Decision ID")
  • [x] to the "Form" section for a user task; the dropdown must only be displayed in the following cases (for the other ones, the binding type is not applicable):
  • implementation type: Zeebe user task + form type: Camunda Form
  • implementation type: Job Worker + form type: Camunda Form (linked)
• [x] Add a tooltip for the dropdown which explains the different options.
  • see suggested design and wording in: https://github.com/camunda/product-design/issues/1811
• [x] We validate the binding type using our usual infrastructure (https://github.com/camunda/camunda-modeler/issues/4386)

Implementation Notes

• The binding type should be stored in the new attribute bindingType in the diagram's XML:

  <zeebe:calledElement processId="test-process" bindingType="deployment" ... />
  <zeebe:calledDecision decisionId="test-decision" bindingType="deployment" ... />
  <zeebe:formDefinition formId="test-form" bindingType="deployment" ... />

• If the attribute is not set, select latest as the default option.

Alternatives considered

None.

Thanks @jfriedenstab. Tagged for 8.6.

Following our normal procedures we'll work on this once the respective feature is merged in Zebee.

This is scheduled on the run-time side of things for 8.6-alpha4. Let's see if we can support it in the modelers at the same time.

Question: If the bindingType attribute is missing, is latest assumed?

[jfriedenstab]

@philippfromme Yes, exactly.

@philippfromme Yes, exactly.

Sorry, found it in the original issue. 😅
