Hi:

I'm using moka to execute a HELLO WORLD model, provided in https://wiki.eclipse.org/Papyrus/UserGuide/ModelExecution,and when i press "debug" button, it says "An unexcepted error occured and see the error log".

Here is the error log:

!ENTRY org.eclipse.papyrus.infra.core 4 0 2019-03-21 16:57:36.860
!MESSAGE Unexpected Error
!STACK 0
java.lang.NullPointerException
	at org.eclipse.papyrus.moka.fuml.Semantics.Loci.LociL1.ExecutionFactory.createExecution(ExecutionFactory.java:86)
	at org.eclipse.papyrus.moka.fuml.Semantics.CommonBehaviors.Communications.ClassifierBehaviorExecution.execute(ClassifierBehaviorExecution.java:60)
	at org.eclipse.papyrus.moka.async.fuml.Semantics.CommonBehaviors.Communications.AsyncObjectActivation.startBehavior(AsyncObjectActivation.java:231)
	at org.eclipse.papyrus.moka.async.fuml.Semantics.CommonBehaviors.Communications.AsyncObjectActivation.run(AsyncObjectActivation.java:104)
	at java.lang.Thread.run(Unknown Source)


If anyone knows the reason please help me!
Thanks a lot

I have solved the problem, that's because I didn't set ClassifierBehavior for the Class.
