In the question about getting selected EObjects I was referring to the 
org.eclipse.emf.ecoretools.diagram.part.EcoreDiagramEditor which, 
unfortunately, does not implement the ISelectionProvider. For generated 
Ecore editors using this provider works perfectly. But, how can I get the 
EObjects which are selected in the diagram displayed by an 
EcoreDiagramEditor?

Thanks for this hint! I'll change my implementation to make use of the 
command framework.
