That example action is a tutorial designed to demonstrate how the optionsCollection tag works. It is not meant to be a starting point for you to develop the functionality you speak of. You are trying to do too many things at once. You need 2 very different pieces of data... - a list of high-level details - a group of low-level details Breaking down the steps allows you to focus your efforts on a specific issue. The 2-action class approach I described allows you to do that. >(supposed to be an entry point and not a resulting page for > our form behavior). This sounds like you want AJAX-like functionality. If you do what is described below, enabling AJAX is made easy because you only have to call details action and render its results AJAX-style.
