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.
