Re: [stp-dev] Problems between the BPMN Modeler and the SCA Composite De

["Antoine Toulme" <antoine@xxxxxxxxxxxxxxx>]

That's a problem on our side, with an easy fix. Please open a bug.

Thanks.

Hi,

I'm experimenting the integration of the SCA Composite designer with the
others tools of the STP project.
I have a problem with the BPMN modeler. I have the two following
exceptions :

 java.lang.ClassCastException:
org.eclipse.gmf.runtime.diagram.ui.parts.DiagramEditDomain cannot be
cast to org.eclipse.stp.bpmn.diagram.part.BpmnDiagramEditDomain
   at

and

java.lang.ClassCastException: org.eclipse.stp.sca.impl.DocumentRootImpl
cannot be cast to org.eclipse.emf.ecore.EModelElement
   at
org.eclipse.stp.bpmn.diagram.actions.AbstractDeleteAnnotationAction.updateSelectedEModelElement(AbstractDeleteAnnotationAction.java:166)
   at
org.eclipse.stp.bpmn.diagram.actions.AbstractDeleteAnnotationAction.refresh(AbstractDeleteAnnotationAction.java:101)

   at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37)
   at org.eclipse.core.runtime.Platform.run(Platform.java:857)
   ...

Moreover some menu items (for example "save image as") on the SCA
diagrams have disappeared.

In the SCA designer I don't see any links to the BPMN modeler. So, I
added, in the BPMN modeler, some code to check the type before making
the cast and everything seems to work correctly. I made these
modifications on two methods :
- org.eclipse.stp.bpmn.diagram.actions.GroupAction.getSelection and
-
org.eclipse.stp.bpmn.diagram.actions.AbstractDeleteAnnotationAction.updateSelectedEModelElement

BPMN guys, do you think that
1) I must open a bug on the BPMN modeler or
2) it's a problem in the plugin.xml file of the SCA Composite designer?
