Validation on input output parameters for bpmn:callActivity

[Pragyansh_Dwivedi]

The requirement is to add “required” validation on input-output parameters of bpmn:callActivity and make it visible on the properties panel UI.

  <bpmn:callActivity id="Activity_00lde5i" name="BPO Common - Create Resource 2" calledElement="bpocommon_ForceTerminateResource">
      <bpmn:extensionElements>
        <camunda:inputOutput>
          <camunda:inputParameter name="input_map_1">
            <camunda:map>
              <camunda:entry />
            </camunda:map>
          </camunda:inputParameter>
          <camunda:inputParameter name="resource_input_1" />
          <camunda:outputParameter name="resource_output" />
        </camunda:inputOutput>
      </bpmn:extensionElements>
    </bpmn:callActivity>

Something like as shown in case of calledElement

To me this sounds like a good use for element templates: About element templates | Camunda Platform 8 Docs.

These allow you to clearly define the contract of particular called processes, including input / output validation.
