[news.eclipse.modeling.gmf] Moving Nodes by dragging a connection

[David Schmelter <schmelly@xxxxxxxxxxxxxxxx>]

Hello again,

Id like to move two nodes in a diagram by dragging the connection 
between these nodes around (I need this for a sequencechart where 
messages between lifelines are connections).

Does anybody have an idea for a general approach to this? E.g. what 
editpolicies i'll need or code to change?


best regards,
David
