is there a way to repaint the connections of an editpart after a command has been executed?
i want to drag a connection between two nodes, but the source end of the connection should be delegated to a child. it's already working except that the connection source is attached to the parent and not the child until i drag some another node onto the diagram. then, the connections are showed properly. i want to repaint the connections automatically. how can i achieve this?

my custom editpolicy:

public class GoalItemSemanticEditPolicyOverride extends
		GoalItemSemanticEditPolicy {
	protected Command getCompleteCreateRelationshipCommand(
			CreateRelationshipRequest req) {
		super.getCompleteCreateRelationshipCommand(req);
		if (XkaosElementTypes.GoalRefinementGoals_4013 == req.getElementType()) {


			return getGEFWrapper(new GoalRefinementsCreateCommandOverride(req,
					req.getSource(), req.getTarget()));
		}
		return null;
	}

my custom command:


public class GoalRefinementsCreateCommandOverride extends
	GoalRefinementGoalsCreateCommand {
	protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
			IAdaptable info) throws ExecutionException {
		if (!canExecute()) {
			throw new ExecutionException(
					"Invalid arguments in create link command"); //$NON-NLS-1$
		}

		if (getUncastedSource() != null && getUncastedTarget() != null) {
						}
			
			if(getUncastedSource() instanceof Goal && getUncastedTarget() instanceof Goal){
				GoalRefinement gr = XkaosFactory.eINSTANCE.createGoalRefinement();
				((Goal )getUncastedSource()).getRefinements().add(gr);
				gr.getGoals().add((Goal) getUncastedTarget());
				
				//TODO repaint root
				
			}
			
			if(getUncastedSource() instanceof Goal && getUncastedTarget() instanceof DomProperty){
				GoalRefinement gr = XkaosFactory.eINSTANCE.createGoalRefinement();
				((Goal )getUncastedSource()).getRefinements().add(gr);
				gr.getDomproperties().add((DomProperty) getUncastedTarget());
			}
		}
		return CommandResult.newOKCommandResult();

	}
