= Problem description =

Original problem description posted by Niranjan Babu form Robert Bosch Engineering India:

I am implementing a GMF based Graphical editor on ARTOP
 
I have done the following
 
I have generated the editor and assciated my file extention *.diagram  with contenttype org.eclipse.sphinx.gmf.diagramFile
 
And I am getting the below exception when ever I am trying to save.
 
Do I have to do something extra to intgrate Diagram file loading into the same Autosar40Editing domain

Comment 1 Stephan Eberle CLA 2011-09-30 08:13:30 EDT 
Fixed by testing target namespace for null before creating a java.net.URI from it in org.eclipse.sphinx.gmf.workspace.metamodel.GMFTargetMetaModelDescriptorProvider.getDescriptor(IFile) and org.eclipse.sphinx.gmf.workspace.metamodel.GMFTargetMetaModelDescriptorProvider.getDescriptor(Resource).
