Created attachment 173503 [details] stack trace
In the type: FlowEditor, in method: initializeGraphicalViewer() the drop target listener is wrong. The template of the TemplateTransferDragSourceListener is the creation tool an not a CreationFactory. So the factory is null and a model object cannot be created. And just for your information: the type FlowElementFactory is not used and can be deleted.
Which Linux is this?
This is on: Ubuntu 10.04 LTS - Lucid Lynx 64bit with Gnome Desktop 2.30.2
Changed implementation of TemplateTransferDropTargetListener#getFactory(Object) to use a SimpleFactory in case the provided template is a class, which seems to be a common use case. This way, the reported problem in the flow example is covered by the default behavior of TemplateTransferDropTargetListener, and a custom implementation does not have to be provided. Removed FlowElementFactory from example, which is not used (and was identical to SimpleFactory). Committed changes to R_3_6_maintenance branch as well as cvs HEAD (3.7).
