BPMN: Boundary Events for CallActivity

Hi,

Using v11.2 of VP ME I’d like to define a message boundary event for a CallActivity element.

If I understand correctly, I’d have to

  • drop the boundary event on the diagram onto the CallActivity element
  • open the specification of the boundary event
  • select the CallActivity element as the target in the specification dialog.

At least this is how I do it for ordinary tasks.

But: The CallActivity element is not listed in the target combo box.

Is this a bug or am I doing something wrong?

TIA
Andre
