Thanks for the feedback. We decided to stick to the dummy parent form method. It is simpler and takes little overhead. All the dummy parent mode had was one dummy block with one dummy field and a two-line key-startup trigger.

As for a form calling itself recursively, if the form is quite large, won't it take up memory if it calls itself ?
