I have a document-based app in which I'm trying to bind the state of
NSMenuItems to values in my document's window controller. For
example, in the window's nib file, I have a checkbox bound to File's
Owner/autoscaleX. I'd like the menu item to have the same
functionality as that check box and to display the status for
whichever window is currently selected.
Since File's Owner is NSApplication in MainMenu.nib I get an
exception when I try to bind to autoscaleX. I tried adding an
autoscaleX action to FirstResponder and binding to that, but I still
get the exception.
I also tried not binding the menu item and just setting its action to
FirstResponder's autoscaleX action, but the menu item remains disabled.
I'm sure there's an easy Cocoa way to do this, but I haven't been
able to dig it up in the docs or my searches.
