NPE Deleting Model Project with Diagrams for models within that project open

Actually got this with "jbosstools-3.2.0.Beta1.aggregate-Update-2010-09-27_05-18-00-H173.zip" kit today.

Couldn't get the NPE in Designer IDE, but there is a bug nonetheless.

DiagramEditor needs in notifyChanged() needs to check if the current diagram eIsProxy() which indicates the EObject is out of scope/unloaded and in this case, being deleted.

java.lang.NullPointerException
