Hi Bruno, not sure if this is the problem but I believe you can not have nested forms. Your view has:
{{form.custom.begin}}
<div class="wrapLogin">
<form action="" enctype="multipart/form-data" method="post">
and
</form>
</div>
<div class="copyrightLogin">© 2011, Groupon Inc. Todos os direitos
reservados.</div>
{{form.custom.end}}
form.custom begin and end contain the opening <form> and closing </
form> tags,
so you will have an invalid construct of a form inside another.
