Just when I thought Bindings were making sense to me, I hit this wall...
Okay, I guess I just assumed at some point along the way that invocations
targeting NSApp where NSApp doesn't respond to that selector were
automatically forwarded to NSApp's delegate, but I can't find that in the
docs anywhere. I have a model object that is my application's delegate. I
want to bind to accessors of said model object, and I tried to do that by
binding to File's Owner (NSApplication) with the model key path of
someAccessor. NSApp doesn't implement someAccessor, but its delegate does.
However, at runtime my NSTextField whose value is bound to File's Owner's
someAccessor shows "Not Applicable" instead of the NSString returned by
someAccessor. I don't get a runtime error, so I checked gdb and found that
my accessor is never called. Am I doing this wrong?
