NSTextField, textDidChange vs. controlTextDidChange

In a slightly convoluted twist, when the value in an NSTextField changes, the delegate does not get what appears to be the obvious textDidChange but rather it gets a controlTextDidChange.  This one had me confused for a while.

Core Data and Bindings

There is a comment in the Apple documentation that clearly states that it is a bad idea to try to deal with learning Core Data and Bindings at the same time.  I am here to say they are right.  I backed Bindings off of my current project and it is going much more smoothly as I am only fighting a battle on one front.
