Drag and Drop doesn't work from ResourceNavigator [message #1790091]

Whenever I drop a file from ResourceNavigator onto Graphiti Editor, the addFeature() doesn't get called and and editor associated from dropped file is launched. In fact, non of the classes in the Graphiti class chain are called. However, if I drop from Project Explorer for example, addFeature() is being called. What could be the issue? I know that DND works because functionality is successful with plain GEF editor.

Alex,

I guess for this you need to provide your own drop target listener and add that to the editor. In DiagramBehavior method createBusinessObjectDropTargetListeners() the default implementation adds a drop target listener for the objects from the project explorer only. I haven't done that but adding your own drop target listener there should enable that.

THT,
Michael
