Errors when adding interruptible regions in an activity diagram in IBM Rhapsody

Question

I have the following activity Diagram that I made in IBM Rhapsody:

I can simulate without issues. But when I want to add an interruptible region, I get the following errors :

And Obviously I am not able to simulate.

Could you please tell me what am I missing here ?

Answer 1

I think Rhapsody simulation doesn't support interruptible regions. This would be consistent with the fUML-specification for executable UML. In this specification interruptible regions are excluded.
