JavaFX 2.0 :: Using Events For Additional Mouse Buttons

Is there a possibility to use events for additional mouse buttons, like the next or previous mouse buttons, in javafx? If I use the setOnMousePressed event on a node, it only throws an event for the "PRIMARY" "SECONDARY" and "MIDDLE" buttons.
 
node.setOnMousePressed(new EventHandler<MouseEvent>() {   
      @Override public void handle(MouseEvent mouseEvent) {
          System.err.println("mouse button: " + mouseEvent.getButton());
     }
});
 
If I use this java application [URL] .... it is also possible to throw events for the next or previous mouse buttons of the mouse. But not in my javafx application.
