Capturing Alt Space in Solaris CDE

Question

Hello.
I have this table in an application. I need to popup a menu when the user presses "Alt + Space", when a row has focus. Obviosly, one should use getInputMap(..), getActionMap(..) methods to register the desired action for this particular keystroke. It works fine in Windows, fvwm window manager. However, in Solaris CDE, the frame's menu pops up.
Question1: Is it possible to capture "Alt + Space" such that it works in CDE too?
I beleive that the application is not getting the event at all. When I press Alt, a keylistener in the table does get the event. However, the moment i press "Space", the frame's menu gets activated.
Question2: Is this order of event handling?
OS gets the event ---> gives it to Window Manager ---> gives it to application?
Any help would be appreciated.
Thanx
Prasanth.
PS: This is the relavant code snippet.
            final String ALT_SPACE_COMMAND = "ALT_SPACE";
            InputMap keyMap = getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
            // Alt + Space shows the popup.
            KeyStroke ALT_SPACE = KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, KeyEvent.ALT_MASK);
            keyMap.put(ALT_SPACE, ALT_SPACE_COMMAND);
            actionMap.put(ALT_SPACE_COMMAND, new AbstractAction()
                     public void actionPerformed(ActionEvent e)
                          showPopupMenuForSelectedRow();
                });

You need to remove a default event from the space bar most probably, look on the api in the keymap class there is a predefined method there
