Call Operation Action not working

[EAButNotForGames]

I am currently trying to access an operation with a state machine.
For some reason my state machine can't access it directly: "sim.operation is not a function"
So the next best thing is, to create an activity diagram with a CallOperation, which then is used by the state machine.
My problem is:
As soon as the Activity Diagram reaches the CallOperationAction, it stops and doesn't go any further.
So I checked the EA Example
Same thing.
All Activity Diagrams, which have CallOperationActions are not working, unless you run the interaction "int setupUSB()" from the package Systems Engineering -> Software -> C++

Does anyone else have this problem and/or knows a solution?

Try this :

1. Open the diagram properties for the diagram that includes the items to be reported on.
2. From the left-hand tree, choose Diagram.
3. Check the checkbox labeled. Add each included element to Documentation.
4. Close the Diagram Properties.
