Extensible Type Registry-which one for addNodeListener [message #145086]

hi,

which would be the right Edit*something of the Extensible Type Registry
to call addNodeListener of my EditPart I want to extend? I want to
listen to changes of an attribute in the SemanticModel?

I looked in the "Developer's Guide to the Extensible Type Registry" but
couldn't find which to take within several hours :(

I'm sorry, I was wrong.

I somehow need to add behaviour to the

handleNotificationEvent of an EditPart

Can I use EditHelpers or EditPolicies to do that or do I have to replace
the whole EditPart?

well, I looked in the GMFGraph.Editor project ... they realized this
with writing a xPand aspect for the editPart.

If someone is interested ;)
(/org.eclipse.gmf/plugins/org.eclipse.gmf.graphdef.editor/te mplates/aspects/xpt/diagram/editparts/NodeEditPart.xpt)

Still nobody got a better solution via extension points? ;(

ok, I got it.

I used an EditPolicy to register a Listener to the EObject.
