In the tutorial example I am trying to drag and drop EClasses to the editor.
When I expand the Ecore model in the package explorer and drag and drop from there, this work fine.
When I open the Ecore model in a tree editor (the default one) and I drag and drop from there it doesn't allow me to drop it in the editor.

What is the difference and what should I do to make them both work?

Jos,

I tried dto debug this, but couldn't get a hook. The Graphiti framework does
not get notified of such a drag&drop operation. It seems that the Ecore
model editor does not support such a drag operation.

I am trying to add drag and drop behavior to my Graphiti diagram. There is, however nothing in the documentation or tutorial on how to deal with it. I can drag and drop an element from my model into a GMF diagram, but if I drag the same object from my model over the Graphiti diagram I only see the "cannot drop" icon. It seems that the drag from my model explorer works because it can be dropped in the GMF editor.

How can I get ahold on what is dragged on the Graphiti editor and how can I handle this ?
