Brad,
I am using DA with framework builder without any issues, the key I think is where you are posting your forms to I use for example in my admin section:
<form action="<?php echo $_SERVER['PHP_SELF'].((isset($_SERVER["QUERY_STRING"]))?'?'.$_SERVER["QUERY_STRING"]:"") ?>" id="frmDelete" method="post" name="frmDelete">
Does that help ?
