We are working on GUI testing of Forte for Java by Jemmy (GUI testing tool, see http://techpubs.Eng.Sun.COM:80/net/ultrapuma/export/ultrapuma4/jemmypages/ if you are interested). We found out that there can exist JPopupMenu which has isShowing()==true, isVisible()==false, popup==null.
I think this is the state in which no component should stay because javadoc of Component.isShowing() says:

    /**
     * Determines whether this component is showing on screen. This means
     * that the component must be visible, and it must be in a container
     * that is visible and showing.
     */

I guess isShowing() method should be implemented in JPopupMenu class such way as isVisible() method, i.e.

    public boolean isShowing() {
        if(popup != null)
            return true;
        else
            return false;
    }
    
Then our tests will find the correct popup-menu.

EVALUATION Submitter didn't provide a test which shows how he creates a PopupMenu with isShowing()==true, isVisible()==false, popup==null. Status changed to not reproducible

EVALUATION Name: pzR10082 Date: 08/13/2001 The submitter's suggestion is quite reasonable, because isVisible() is redefined in JPopupMenu. java.awt.Component.isShowing() unfortunately doesn't call isVisible(), it checks value of package private variable 'visible' instead. So if we override isVisible() we should probably override isShowing() too. ###@###.### 2001-08-13 ======================================================================
