Modelelement with no corresponding EditPart [message #529856]

Hello guys,
I'm currently working on a customised view for my EMF Models.
In the EditpartFactory I create EditParts for the model elements. But now I have some Model elements dont neew to show in the editor view, so I dont need editparts for them. Whats the proper solution for that? E.g. returning null in the EditPartFoactory throws an exception.
Kind regards
Patrick

Sounds like you need to filter out those elements from the model.

Yeah, but where to filter out?

The model that you present to your GraphicalViewer will be the model
used by your EditPartFactory. So for every child in the model you must
return an EditPart. Therefore, I would create a diagram model for the
viewer based on the domain model.

Just don't include the unwanted model objects in the list you return in
the getModelChildren(). For these the editpart tries to create children
editparts with the editpartfatory.
