Re: Problem with NSMenu -addItem and -removeItem

I'm having a problem with the NSMenu / NSMenuItem classes. I want a certain menu to be visible in the menu bar only if a certain window is visible. To that purpose, I've implemented the two delegate messages of NSWindow:

- (void)windowDidBecomeMain:(NSNotification *)aNotification
{
[mainMenu addItem:simulationMenu];
}

- (void)windowDidResignMain:(NSNotification *)aNotification
{
[mainMenu removeItem:simulationMenu];
}

The menu is added to the menu bar when the window becomes main for the first time, and is properly removed from the menu bar when the window resigns main.

Unfortunately, this works only once. After the menu has been removed once,
it does never appear in the menu bar again :-(
(I've added code to print the [mainMenu description], and the interesting thing is that it looks all right -- the simulationMenu is correctly added and removed; it simply doesn't appear on the screen!)

Can anybody help me with that? Is there something like the old DrawMenuBar that you have to call to update the menu bar?

This was a bug in 10.0.x and has been fixed for 10.1. Unfortunately, the only workaround for 10.0.x is to create a new menu instead of adding the old one back in again.
