HTML_QuickForm_Controller + URL parameters

Hi! I can get the QuickForm_Controller to work except for when I have a page that receives parameters (related to page navigation) via the url. For example I have a plain page that loads at index.php without the form, but index.php?page=1 loads a page with the form. Therefore when I submit the form it takes me back to index.php, instead of index.php?page=1. I've noticed that the QuickForm_Controller does not let you load a custom action for the form's attributes, so I can't load the action in the form directly as I could with QuickForm. Is there a solution, or am I just doing something completely wrong? I have tried modifying the constructor for HTML_QuickForm_Page to include an action parameter. That implementation worked correctly with the wizard examples, however I am not sure of the side effects caused by this alteration. I have also tried to access the page's attributes array directly, however, I could not modify the form's action. FYI, I have tried RTM and searching the newsgroups for an answer, and I can't find anything. I've only started working with QuickForm today -- so I apologize if I'm missing something completely obvious. Thanks!
