    // negative Link event can result in increase of edge ports
    boolean addEdgePort = event.type() == LinkEvent.Type.LINK_REMOVED;

    // but if the Link is an Edge type, it will be the opposite
    if (event.subject().type() == Type.EDGE) {
        addEdgePort = !addEdgePort;

    if (addEdgePort) {
