Thanks for taking the time to look at my code guys,
I ended up taking mmalc's advice, and rewrote the datasource sans
arrayController/bindings.
it took me less than 2 hours!

First, sorry about my last post with the "RE:Contents of ..." title.
My bad.
Anyhow, I figured out what was wrong. Seems you need to call
[self.view addSubview:picker] to "hook up" the picker to the view
controller. I am doing that in my viewDidLoad method.

This should work but would make most sense in viewDidAppear if the user should
be able to enjoy the animation.

You have set the Pickers delegate?

Hi Phillip,
Hmm, I don't think your solution will work for me. I don't have a

Is there any method anywhere that deselects, either in the table cell or

Ahh, now I see it, you are correct. I had been alloc/init'ing some
other UI elements that were not created in IB, and this got that
treatment, too, so the picker was double-allocated. I need to more
careful copy/pasting my own code.
