Another possibility is that there is an invisible character in your

Delegate methods aren't sent at all unless the delegate implements
them. I think your delegate is going to have to implement all
possible delegate methods and then forward them *if* the old delegate
implements them, and otherwise return an appropriate default value if
there is a return
The doc I found says there are *two* ways a custom view is
initialized. One uses initWithFrame:, the other doesn't. Are you
sure your case is the first case? It sounds like it, but I thought
I'd double-check.

Good question -- if you want the double action to be called, you have
to set the app controller to be the table view's target, not just its
