UndoManager for NSApplication

Subject: UndoManager for NSApplication

Hi

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.

Thanks
Reza
