When I'm adding form on my facebook Box FBML page like so:
<form action="rel_action" method="post">
<input type="text" name="inp_text" />
<input type="submit" name="sbm_send" value="GO!" />
</form>
Facebook will post it on my application URL -- What I would like to do is that browser would stay my Box tab and use ajax (like it does with normal links).
Example how I would like it: http://www.facebook.com/audi#/audi?v=app%5F68682102181
