Edges are created in two ways:
1) by the GraphicalNodeEditPolicy - that's when you use the connection
tool and drag with the mouse
2) by a CanonicalConnectionEditPolicy that listens to the model and syncs
it with the notational model
So very likely, a CanonicalConnectionEditPolicy is not turned off when it
should be. This happens when the connections are owned by a model element
that's not either the source, target or immediate container of the source
and target of the connection.
So you can either change the ownership of connections in your model, or
subclass GraphicalNodeEditPolicy and install that new editpolicy on the
edit parts that act as ends to the connection:
Here's an example (look for //cc.compose( new CommandProxy(viewCommand) );)
public class B2GraphicalNodeEditPolicy extends GraphicalNodeEditPolicy {
/**
* Gets the command to complete the creation of a new connection and
* relationship.
* <p>
* We override because we return a command that operates on the semantic model only.
*
* @param request
* @return Command
*/
protected Command getConnectionAndRelationshipCompleteCommand(
CreateConnectionViewAndElementRequest request) {
// get the element descriptor
CreateElementRequestAdapter requestAdapter = request
.getConnectionViewAndElementDescriptor().getCreateElementReq uestAdapter();
// get the semantic request
CreateRelationshipRequest createElementRequest = (CreateRelationshipRequest) requestAdapter
.getAdapter(CreateRelationshipRequest.class);
createElementRequest.setPrompt(!request.isUISupressed());
// complete the semantic request by filling in the source and
// destination
INodeEditPart targetEP = getConnectionCompleteEditPart(request);
View sourceView = (View)request.getSourceEditPart().getModel();
View targetView = (View)targetEP.getModel();
// resolve the source
EObject source = ViewUtil.resolveSemanticElement(sourceView);
if (source == null) {
source = sourceView;
}
createElementRequest.setSource(source);
// resolve the target
EObject target = ViewUtil.resolveSemanticElement(targetView);
if (target == null) {
target = targetView;
}
createElementRequest.setTarget(target);
// get the create element request based on the elementdescriptor's
// request
Command createElementCommand = /* targetEP
.getCommand(new EditCommandRequestWrapper(
(CreateRelationshipRequest) requestAdapter
.getAdapter(CreateRelationshipRequest.class), request.getExtendedData()));*/
new ICommandProxy (new CreateSegmentsCommand((End) source, (End) target));
// create the create semantic element wrapper command
if (null == createElementCommand)
return null;
SemanticCreateCommand semanticCommand = new SemanticCreateCommand(
requestAdapter, createElementCommand);
// get the view command
Command viewCommand = getConnectionCompleteCommand(request);
if (null == viewCommand)
return null;
// form the compound command and return
CompositeCommand cc = new CompositeCommand(semanticCommand.getLabel());
cc.compose( semanticCommand );
//cc.compose( new CommandProxy(viewCommand) );
return new ICommandProxy(cc);
}
}

Hi Vlad, i couldnt put your pasted code to work.
I have a XXXGraphicalNodeEditPolicy and i couldnt understand the
// get the create element request based on the elementdescriptor's
// request
can you past the imports too? or maybe a more detailed code (if possible)?
thank you so much!
