Hi,
I'm trying to get the editor to display my model. Below is the
initializeGraphicalViewer() method. The program would work if I would
call viewer.setContents(null), but not display any data.
/**
* @see
org.eclipse.gef.ui.parts.GraphicalEditor#initializeGraphical Viewer()
*/
protected void initializeGraphicalViewer() {
EditPartViewer viewer = getGraphicalViewer();
viewer.setContents(new NetworkViewAdapter());
}
When I run my program I have the editor open with a red error message in
it saying: "An error has occured when creating this editor".
The exception I get in the log file is the following:

I base the code on Jeffrey Bonevic's SimpleGef example, however, I added
my own implementation of IEditorInput as I don't have files (my editor
should not be persisted).
I'd be glad if someone could enlighten me and tell me what I'm doing wrong.
Thanks in advance,
Christian
Here's some more code that might be interesting to some of you while
trying to help me.

Hi Christian,
You need to set the EditPartFactory() onto the EditPartViewer
when you call setContents();
