I have menus in my component that I would like to be accessible via the JMenuBar and a JPopupMenu.  The problem is that I can't use just 1 instance of the menu and pass it to the menubar and popup; I have create 2 instances, adding the 1st to the menubar and 2nd to the popup.

Here's what I am trying:
    JMenuBar mb = new JMenuBar();
    JPopupMenu pum = new JPopupMenu();
    JMenu jm = new JMenu("Stuff");
        ... add menu items to jm
    mb.add(jm);
    pum.add(pum);

However, the above code leads to only pum showing the "Stuff" menu.

Is this a bug (OSX 10.2.8, Java 1.4)?


No, this is a misconception on how JMenuItems work. From the "How to use Menus" tutorial on Sun's website:

Note: Menu items, like other components, can be in at most one container. If you try to add a menu item to a second menu, the menu item will be removed from the first menu before being added to the second. For a way of implementing multiple components that do the same thing, see How to Use Actions.
