How to refresh screen in BlackBerry?

Question

I use this on one of my screen:

protected void makeMenu(Menu menu, int instance){
if (UserData.sessionId != null){
    menu.add(logOut);
    menu.add(setting);
}
menu.add(exitApp);

}

The "log out" and "setting" menu only appear after the user logs in (hence, the session ID is not null). How to make the "log out" and "setting" disappear from the menu after the user logs out, while the same screen is still being displayed?

invalidate() ?

Answer 1

makeMenu() should be called every time you press the menu button so you should not need to repaint. Is the UserData.sessionId being correctly updated once the user has logged out?

Also you should call super.makeMenu() when you override makeMenu()

I can't post a link to the java doc as I don't have enough reputation but that is mentioned in there.
