Christoph,
I would guess that your view part needs to implement ISelectionProvider...

Hello Ed,
thank you for your reply.
I thought if would be sufficient if I register the TreeViewer within my ViewPart as a selection provider (getSite().setSelectionProvider(treeViewer)).
I use the standard org.eclipse.ui.views.properties.PropertySheet as my property view. And I can also see in the debugger that the selectionChanged method on the PropertySheet is invoked when I select an (EMF-object)element in my TreeViewer of my ViewPart (the selected element is contained in the TreeSelection object).
But the PropertySheet remains empty.
NB: When I select an element in a View that is based on org.eclipse.ui.views.ContentOutline, the properties are visible in the PropertySheet.
Can you give me some more hints if possible?
Thank you very much and cheers,
Christoph

Hmmm. One would hope so yes...

I see. Note that the generated editor implements getAdapter to create
the appropriate properties view implementation, so you'd need to do that
too for your viewer...

Hopefully that's a good hint...
