Hi everyone,
I have two nodes that I connect with a Connection.
The ConnectionCommand is correctly created via the
getConnectionCreateCommand of the nodes EditPolicy.
When I click on the target Node, the ConnectionCommand is executed, the
Connection model is created, and event is fired, the Connection EditPart
is created and then... nothing. The createFigure of the Connection
EditPart is never called and the Connection does not display on the Viewer.
What did I miss?
Bruno

are you calling refreshSourceConnections() at any placed?

Randy,
thanks. I was not using an instance of AbstractConnectionEditPart for my
connection and had not realized that the notification mechanism is
different from "standard graphical" EditParts
