Programmatically Accessing Call Activity's Extension elements

Since activiti doesnt support out parameters for call activity nodes that use multiInstanceLoops I am trying to implement my own solution to this. Basically every subprocess would right back its out variable in a Map. I have hit a snag though. I can' t figure out how to get the list of the parent pr

Hi Jorell,

activiti doesnt support out parameters for call activity nodes that use multiInstanceLoops

I did not test it, but it can make sense -> variable can be overridden by the next loop. Some kind of mapping is needed.

But the call activity has no extension elements.

org.activiti.bpmn.model.CallActivity has lists of inParameter and outParameters.


  protected List<IOParameter> inParameters = new ArrayList<IOParameter>();
  protected List<IOParameter> outParameters = new ArrayList<IOParameter>();

Is there something in case of multi instance loop?

Regards
Martin

Thanks Martin. Yes I am trying to create a custom mapping for each multiInstance loop in a call activity.

Yes the CallActivity object does have inParamaters, outParameters and it also has a list of ExtensionElements. But all these are empty at run time when I put a break point and and inspect the CallActivity. They don't seem to be getting set.

Actually scratch that, the out parameter is set and I can see my variables correctly in there. Not sure why I missed it earlier. Thanks for your help Martin!
