Bindings and Core Data don't do everything for you. :-) Just a few
days ago, mmalc (quite correctly) said, "sometimes you just need to
write some code".
In this case, you're doing something outside your array
controller's purview, so you need to tell it to -fetch: which means
sending it a message. This in turn means (in your situation) an outlet
to the array controller in your nib. This is perfectly normal (in
fact, it's damned near impossible to avoid :-D).
Take-home message: Don't feel you're doing something 'wrong' or
'dirty' ... you're on the right track with an outlet.
