Form Generation Library

Hi, and thanks for the great job.
I have a question about using 2 or more form in the same page.
I think I followed your doc (about the clear method) but I don't get what I'd like.
Here's my code:

$this->load->library('form');
$this->form->text('testo','testo','required|numeric|trim|max_length[2]');
$this->form->text('testo2','testo2','trim|required|matches[testo]');
$this->form->submit('invia1');

$this->data['form1'] = $this->form->get();
$this->form->clear();

$this->form->text('testo3','testo3','trim|required|numeric');
$this->form->submit('invia2');

$this->data['form2'] = $this->form->get();

$this->form->validate();

if ($this->form->valid) {
if ( $this->input->post('invia1') ) {
die('ok: 1'.anchor('test/fmform','go back'));
} else {
die('ok: 2'.anchor('test/fmform','go back'));
}
}


$this->data['errors'] = $this->form->errors;
$this->load->view('fmform',$this->data);

what happens is that the field in the second form generates an error if I submit the first form. I also tried separating the error messages after the $this->form->get(), but it doesn't seem to work (only errors from the first form appear).
Before looking at the code, I'd like to know if this is the way I'm supposed to do it.

Thank you.
