Adding Elements dynamically in HTML_QuickForm_Controller?

Hi, I'm trying to use HTML_QuickForm_Controller to allow end users to edit records in a Normalized Database. One of the fields that is in a record can have zero to N (where N maxes out around 50 currently I think) text fields. I'm using the tabbed.php example as my base to build on for this set of pages. I'd like to make it so that the user can just goto the tab in the form for that data, and start adding these field(s) as needed. The form would start with just one field. I assume there would need to be a button the form page to all another element, using the $this->addElement('text','field${n}','FieldVal${n}'); But I'm not sure how to implement this. I relize I'd need to setup a new class, but would I have to reset the variable $this->_formBuilt to be false when I made the change, so as to force it to visible? For now, I can deal with just adding elements to the form, I'd just ignore any empty elements when I did the actually data insert into the DB. Can anyone point me to an example which shows me how to make this work?
