cancelActivity = true in boundary event does not cancel process flow

Hi,
I am currently playing around with SignalBoundaryEvents. I have this simple BMPN model depicted here http://imgur.com/aPxAgJE and outlined in xml below:

The whole thing will loop service task 1 -> service task 2 -> service task 3 until a signal is received in the sub process that contains service task 2 which will lead to a SignalBoundaryEvents and ultimately to the termination of the whole thing.

When i trigger the signal via

….
Execution exec = runtime.createExecutionQuery().signalEventSubscription("System Signal").singleResult();
if(exec != null){
  runtime.signalEventReceived("System Signal", exec.getId());
}
‍‍‍‍‍‍‍

things go as planned, i.e., the SignalBoundaryEvent is triggerd and consecutively the service task connected it is triggered leading to a terminateEndEvent. Eventhough I have set cancelActivity in the Boundaryevent to true  the process resumes with the loop ultimately leading to a org.activiti.engine.ActivitiObjectNotFoundException , which is confirmed when looking at the output of an EventListener

Any ideas / hints on what I am doing wrong would be highly appreciated (I am using activiti 5.17.0).

Thanks in advance,

Hi Konrad,

Could you prepare jUnit test please? (http://forums.activiti.org/content/sticky-how-write-unit-test)
