Quick Form controler

Hi, I'm trying setting special action attribute of <form tag while using Quick_form wizard. The problem is that i'm using dispatcher file index.php where I decide which page to show for example http://foo.bar/wizard/ but when I klik next script redirects to foo.bar/index.php. I set update attributes in FirstPage class and <form tag is rendered fine, but clicking next always redirects to index file Is it possible to set something else like in Quick_Form constructor. regards Uros
