I had occasion to use an @min aggregate function, but it seems to
be only half implemented. In particular, I have an
NSArrayController set up with an input content set and then a
binding of email@hidden to a minimumMyKey on itself
(so that I can do something fun in -setMinimumMyKey:).
Controllers ignore change notifications that they emit themselves
(they already know about the change...).
If you observed the key from another object, you should see the
notification.
For the benefit of google, yes this work fine. I had a silly bug
that prevented this from working. There's nothing like posting to a
mailing list to make the problem become apparent...
