Description Navid Mehregani CLA 2010-09-27 18:29:58 EDT 
Build Identifier: 

Conversion to Association and Association Class makes the incorrect assumption that the association ends are always managed entities.  This results in the indicated ClassCastException:


java.lang.ClassCastException: org.eclipse.tigerstripe.workbench.ui.visualeditor.diagram.edit.parts.SessionFacadeArtifactEditPart cannot be cast to org.eclipse.tigerstripe.workbench.ui.visualeditor.diagram.edit.parts.ManagedEntityArtifactEditPart
at org.eclipse.tigerstripe.workbench.ui.visualeditor.diagram.part.AbstractConverter.run(AbstractConverter.java:122)
at org.eclipse.tigerstripe.workbench.ui.visualeditor.diagram.part.ConvertAssociationToAssociationClass.run(ConvertAssociationToAssociationClass.java:18)
at org.eclipse.ui.internal.PluginAction.runWithEvent(PluginAction.java:251)
at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:584)
at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:501)
at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:411)

Reproducible: Always

Steps to Reproduce:
1. Create an association between two session artifacts
2. Convert the Association to an Association Class by right clicking on it in diagram view.  Look at Error log.

Don't affect that we also allow associations (and I assume association classes) to association classes

possible association class usage, but not probable
