SignalBoundaryEvent not saved in BPMN File

[kkdw]

Dear all,

I am trying to include a SignalBoundaryEvent in one of my Subprocesses. I want to throw the signal into Activity from outside so there is no SignalThrowingEvent in the Subprocess.

After adding the SingalBoundaryEvent and saving the diagram the corresponding bpmn File (located in src/main/resources/diagrams/) will not get updated and the SignalBoundaryEvent is not incorporated in the BPMN-model. Even after removing the Event again from the diagram and adding other items like serviceTasks and sequenceFlows the diagram will not get updated (unless the update opdion (ctrl+f5) is used). This problem seems to occur specifically with  SignalBoundaryEvents. ErrorBoundaryEvent/TimerBoundaryEvents work fine. Am I missing something or is this a bug?

I am using Activiti 5.17.0 and for the modelling the Activiti Eclipse BPMN 2.0 Designer 5.15.0.201407081458, within the Eclipse Luna Service Release 2 (4.4.2).

Cheers,
Konrad

Short edit (as editing the original post doesn't seem to be possible): [ctrl+f5] does not seem to work, even when the SingalBoundaryEvent  is removed from the diagram. I have to restart eclipse, which resets the diagram to the BPMN-model prior to including the SingalBoundaryEvent. Then editing the diagram and saving is possible again once an update [ctrl+f5] is performed.
