Hi,
I am having a problem with the mapping of the model to =
ConnectionEditPart. In refreshSourceConnections(), GEF identifies that =
there is no EditPart for the model Connection class and queries the =
EditPartFactory to get the ConnectionEditPart. Till here it is fine. I =
want to know when is GEF updating the EditPartRegistry with this new =
mapping. My problem is that in refreshTargetConnections(), the =
EditPartRegistry doesn't contain the earlier model Connection class and =
thus returns null. Because of this GEF is again creating the =
ConnectionEditPart.
The outcome is that my diagram has 2 connections from node A to node =
B and both of them are broken. In one of them the source is null and in =
the other the target is null. So I have weird lines coming from (0, 0) =
to the nodes. Can someone please tell me what's wrong ?
Thanks in advance,
Pavan

additionally, the EditPartRegistry's HashMap is storing the =

What is this "Object" that it is being stored against? Does your =
ConnectionEditPart return the model Connection in its getModel() method?
