    Vertex source = (Vertex) getRequest().getSource();
    Vertex target = (Vertex) getRequest().getTarget();
    if (source != null && target != null) {
        Transition transition = SGraphFactory.eINSTANCE.createTransition();
        source.getOutgoingTransitions().add(transition);
        transition.setSource(source);
        transition.setTarget(target);
        source.getOutgoingTransitions().add(transition);
