Hello!
I´ve got a really strange problem with my GMF editor. I was forced to
restructure my project to fit into another one. So I´ve changed the name
in the ecore package properties and altered the base package of the
genmodel. The code creation worked flawlessly. But as i tried to create
a new diagram at Runtime I got a NullPointerException and the whole
Diagram View couldn´t be displayed. This problem solved itself (very
strange). Now I can create Diagrams as I used to but the strange thing
is that the property views of the Nodes are empty. The models the
generated code is based on seem to be exactly the same up to the name
changes. Does someone have a clue what´s the problem in this case?
Greetings,
Christian Dänekas

I'm having the same problem here (GMF 1.0.100 20070921-0000, build id 2.0.1).
The appearance properties show up fine, but the model properties don't.
The genmodel file shows that all properties are set to editable, except those
which are both references and container/contained (i.e. the nodes which are
treated as child nodes in the EMF editor). I've also regenerated the edit code,
but the only changes were removals of unused imports and some whitespace changes.
Adding a System.out.println() to the getSemanticElement() method in
diagram/edit/policies/XXXBaseItemSemanticEditPolicy.java doesn't show anything
on the console?
I tried overriding the getAdapter() method as suggested in another thread on this
topic ("Re: SOLVED EMF properties view, with EMF attributes"), but that gave this
backtrace (after resolving all those imports...) :
