Popup menu on menuItem

Question

I want to show the popupmenu when users do the right click on the menuitem to do something like the mozilla or internet explorer Favorites menu which can be do right click to show the popup.
I tried this, but i always have the following problems:
1) I open the popupMenu with the popup.show( jmenuitem, mouseEvent.getX(), mouseEvent.getY())
I got the error : java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location
private JMenuItem getAddMenuItem() {
          if (addMenuItem == null) {
               addMenuItem = new JMenuItem();
               addMenuItem.setText(" Favourites    ");
               addMenuItem.addMouseListener(new MouseAdapter() {
                    public void mousePressed(java.awt.event.MouseEvent e){
                         System.out.println("Mouse Pressed: "+e);
                         if(SwingUtilities.isRightMouseButton(e)){
                               System.out.println("Right mouse action");
                         if(SwingUtilities.isLeftMouseButton(e)){
                              System.out.println("Left Mouse action");
                                               //Here i will open a dialog for the user
                                 public void mouseReleased(java.awt.event.MouseEvent e) {
                         System.out.println("Mouse Released: "+e);
                         if(SwingUtilities.isRightMouseButton(e)){
                               System.out.println("Right mouse action");
                               addMenuItem.add(getPopUpMenu());
                               if (popUpMenu.isPopupTrigger(e)){
                                    System.out.println("Triggered2");
                                    popUpMenu.show(e.getComponent(), e.getX(), e.getY());
                         if(SwingUtilities.isLeftMouseButton(e)){
                              System.out.println("Left Mouse action");
               });     so how can i make the menuItem available on the screen to add the popup menu to it?

I didn't see your code but a meunitem on a menu can be another menu. I think that shoud be enough for your requirement.
