Hi,
after migrating from Eclipse 3.5.2 to Eclipse 3.6RC2 and so on GMF 2.3RC2, I encountered a NPE in XXXDiagramEditor.getEditingDomain
The stacktrace:
org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException)

This append when I close the editor.
I notice that the getDocumentProvider() method return null.
Any idea what is the cause?
How to solve it without editing generation template?
What has changed in Lifecycle that can produce this issue?
Regards
