Re: Undo manager

Hi,
after some test more I have seen that only one window doesn't register
   
    [[self undoManager] setActionName:@"Move Object"];

No matter if I specify my own undoManager or use he default one.
However when I call the menu item "Undo" it works well. So please why one
window only shows all the time a generic "Undo" menu item name?

Also, I have seen that, when I launch the application, the menus "Undo" and
"Redo" are deactivated. This is right. But when I activate that window (even
clicking on its window bar), the "Undo" and "Redo" menu items become
activated. And no action (obvious) is performed when I call them. Why?


Best Regards
