how to use GraphicalNode and CanonicalConnection EditPolicy together [message #10006]

Hi all,

I've tried several setups for CanonicalConnectionEditPolicy but I
keep getting duplicated links for my connections.

For one model connection, there is one link that gets created by the
GraphicalNode policy and another by the CanonicalConnection policy.

What's the proper way to use the Canonical policy?

thank you
vlad

Found the culprit in
org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPa rt:

/**
* Return a list of editparts who's canonical editpolicies should be disabled
* prior to executing the commands associated to the supplied request.
* This implementation will return the editpart honoring a <code>SemanticWrapperRequest</code>
* and a <code>CreateConnectionViewRequest</code>'s source and target editparts.
*
* @param request a request that has returned a command.
* @return list of editparts.
*/
Collection disableCanonicalFor( final Request request ) {
//
// not the most generic of solution; however, it will have to do for now...
//
// Alternate solutions
// 1. common request interface on all the requests
// IRequest#getAffectedEditParts
//
// 2. Traverse down the command and collect of the ICommand#getAffectedObjects()
// -- this requires that all our commands properly set this value.
