I want to create a view with 2 tables side by side, where selecting the row on 1 table effects the content of the other and vice versa (not parent child). My problem is how to send the request.

I started with a utility app using core data, and added 2 table view controllers. I added these to the main view nib and moved the tables to the view. One table controls a list from Core Data, then on selecting a row I want it to move to the other table which is based on a mutable array.

On didselectrow I want to tell the other table to update, however I can only find samples that are parent/child so involves initializing. Does anyone know of a way to do this for an active view?

Thanks heaps for your help.
