Call Activity Multi-Instance 'return'-Variables

[se040]

Hi everybody,

i have a process in which a Call Activity is called multiple times as a sequential Multi-Instance Activity. The only problem is that the "return"-Variable (activitiut) from the Call Activity never seems to be set after finish so that i can't use the required variables. I have created a Workaround by using a "hand-written" counter and an exclusive gateway to create a loop around the Activity and it works fine like that. I would much rather use the Multi-Instance solution, so I am wondering if I stumbled over a bug or I screwed something up.

<callActivity id="callProcess" name="Call activity" calledElement="callProcess4">
      <extensionElements>
        <activiti:in source="instances" target="callInstances"></activiti:in>
        <activiti:in source="currently" target="callCurrently"></activiti:in>
        <activiti:in source="objects" target="callObjects"></activiti:in>
        <activiti:in source="result" target="resultInCall"></activiti:in>
        <activitiut source="resultInCall" target="result"></activitiut>
      </extensionElements>
      <multiInstanceLoopCharacteristics isSequential="true" activiti:collection="instances" activiti:elementVariable="currently"></multiInstanceLoopCharacteristics>
</callActivity>

I have created this demo to check if there was something wrong with my original Process but I got the same result. The variable result is set before call to a certain String and set to a different one after it, only that it is the same after as before the call activity.

I am thankful for any help.

Thanks in advance,
Stefan

Multi-instance call activity output parameters does not work (or is not implemented) in 5.11 as per my understanding.

Has this been implemented for 5.12? And, if not, is there an expected implementation date for this?

No, there's currently nothing planned like that.
