Problem you would like to solve

camunda/camunda#28220 is adding support to configure a completionCondition and a cancelRemainingInstances attribute to ad-hoc subprocesses. This should also be configurable through the properties panel in web and desktop modeler.

An example XML definition according to the BPMN spec (see page 196):

<bpmn:adHocSubProcess id="MyAdHocSubProcess" name="My Ad-Hoc Subprocess" cancelRemainingInstances="true">
    <bpmn:extensionElements>
        <zeebe:adHoc activeElementsCollection="=[&#34;A&#34;, &#34;B&#34;]"/>
    </bpmn:extensionElements>
    <!-- incoming/outgoing, tasks, ... -->
    <bpmn:completionCondition xsi:type="bpmn:tFormalExpression">=true</bpmn:completionCondition>
</bpmn:adHocSubProcess>

Proposed solution

Make the following 2 optional attributes settings configurable through the properties panel of an ad-hoc subprocess:

The checklist below follows the format of the issue which initially added ad-hoc subprocess support:

• Attributes can be configured in properties panel: feat: add completionCondition + cancelRemainingInstances properties to ad-hoc subprocess bpmn-io/bpmn-js-properties-panel#1114
  • completionCondition can be defined in properties panel
    • it is FEEL
    • it is optional
  • cancelRemainingInstances can be defined in properties panel
    • it is a boolean/switch
    • it defaults to true
• both attributes are supported in 8.8 config of camunda/bpmnlint-plugin-camunda-compat: feat: add rules for ad-hoc subprocess completion configuration bpmnlint-plugin-camunda-compat#196
• camunda/linting integration
  • When FEEL error is clicked, the properties panel entry is focused
  • (may be already done) Verify the errors are human-readable
• User guidance (e.g. via tooltip) and a link to documentation is provided
  • TBD update documentation link to jump to specific documentation block?
• Make sure documentation is released together with adding the 2 new attributes
• Integrate into camunda-bpmn-js
• Integrate into Desktop Modeler

Additional context

Needed for 8.8
