Java SE (Java Platform, Standard Edition)

How can I get the location of the JMenuItem on the screen in actionPerformed.
When I use the function getLocationOnScreen() on JMenuItem or the object retruned by getComponent() I get IllegalComponentStateException.
I have figured out that inside actionPerformed the parent of the JMenuItem which is JPopupMenu (that contains the JMenuItem) is not visible anymore (its isVisble() function returns false).
Then how can I get the location on the screen of the JMenuItem or it�s popup menu such that I can use it in subsequent call to SwingUtilities.convertPoint(JMenuItem, int x, int y,frame), as I need to display a modal dialog box relative to the position of the popup menu in it�s frame.
