I am trying to implement Craig Ambrose's Redbox for some form submissions. Ideally for me, when the user selects "Add contact" a redbox modal window should open with the New Contact form and on submission, the contacts select box on the main page should get updated with the newly added contact. I was looking into invoking Redbox from the controller for this (http://ahref.in/8dc58) but I couldnt quite grasp the discussion there. Can Redbox be brought in here without too much trouble? thanks again for you inputs!
