Renaming a SubprogramCall throws ClassCastException #1021

Closed RyanMcilnay closed 6 years ago

RyanMcilnay commented 6 years ago

While using the graphical editor to rename a SubprogramCall, a ClassCastException is thrown. We believe it is due to a problem with org.osate.aadl2.impl.BehavioredImplementationImpl#getSubprogramCalls not returning the correct list.

Stack Trace:


java.lang.ClassCastException: org.eclipse.emf.ecore.util.BasicInternalEList cannot be cast to org.eclipse.emf.ecore.EStructuralFeature$Setting

philip-alldredge commented 6 years ago

To clarify, we believe this is due to the result being of a type unexpected by EcoreUtil's cross referencer. There is a TODO statement in getSubprogramCalls() which may be related.

philip-alldredge commented 6 years ago

@RyanMcilnay found a side effect of the fix while working in the graphical editor. While editing a model, he received a write transaction error while the model was being serialized. It was triggered by creating a model with multiple subprogram calls then adding another model element such as a mode transition or a classifier.

@lwrage It seems that adding to the collection with all the subprogram calls is attempting to modify the model. Perhaps the original implementation was correct and the problem was with the definition of the subprogram calls feature? The AADL ecore model indicates that the subprograms calls for behaviored implementations can be changed. This does not seem correct to me as it is derived from the subprogram call sequences. I'm not sure how the original EMF cross reference class works, but I would hope that it only accesses features that are editable which would remove requirement for the result to implement Setting. I'm not an EMF expert so take that with a grain of salt.

lwrage commented 6 years ago

Is this reproducible? Do you have an AADL project I can use to reproduce the exception?

philip-alldredge commented 6 years ago

Yes. I have two way to reproduce it.

  1. Handler which modifies the model programatically. https://gist.github.com/philip-alldredge/43e76c03b95b6b1e82b9d0142a963e9c

  2. Attached project. subprogram_call_test.zip

    • Open the diagram but not the AADL file. The resource behaves differently if it is created by the xtext editor.
    • Create a subcomponent using the graphical editor.
