      EventListenerListHelper propertyChangeListeners = getPropertyChangeListeners(propertyName);
      if (propertyChangeListeners.hasListeners()) {
        PropertyChangeEvent event = new PropertyChangeEvent(delegateFor, propertyName, Boolean
            .valueOf(oldValue), Boolean.valueOf(newValue));
        propertyChangeListeners.fire("propertyChange", event);
