Has anybody else encountered the following bug with the new Eclipse BPMN editor (the one recently rolled out with 5.3) ? :
After creating a few tasks and gateways, the graphical diagram shown on screen suddenly disappears. Viewing the underlying XML source shows that the bpmndi-based tags (i.e. those belonging to the namespace that contain the graphical layout information) have disappeared. All the bpmn2 tags are intact however.
There is no apparent way to get the drawing back.
