I would like to have the facility of undoing deleting of a window. The best way that I thought I could do this is was to use the UndoManager belonging of my NSApplication. However when I try to get the undoManager for the application by calling:
	[ NSApp undoManager ]
I get a nil pointer. Also I could not see any straight forward way of setting an undoManager for a NSResponder. Any suggestions how I can resolve this issue.

AFAIK, of the NSResponders only NSWindow creates its own NSUndoManager. Now, any responder on a window will automatically search up the responder chain for an undo manager, so it should automatically get the window's.
