I'm wondering whether it's possible to implement a GEF editor without making use of NodeEditPart & ConnectionEndpointEditPolicy().

My model doesn't follow the structure GEF seems to assume, in that connections aren't children of nodes. Instead they're children of the graph.

I'm having major difficulties with refreshing figures (cf. http://www.eclipse.org/forums/index.php/mv/msg/458085/1016992/#msg_1016992), because I cannot include connections in a NodeEditPart's getModelChildren() method, but neither can I include them in the GraphEditPart's getModelChildren(), as they need to be registered with the NodeEditPart's getModelSourceConnection() and getModelTargetConnection() methods... Trying to get them as model children in the GraphEditPart leads to an index error (quite obviously).

The only way out I can see is to neglect the usage of NodeEditPart altogether and do everything manually. But will this work?
