It is just out of the box, and it is not set at all, even the first time the controller is loaded. When I am viewing the source of the form in the browser the value of the hidden field is empty, and it of course sends a validation error (this field is required...).
Could you post a sample code on how you are using the nonce function in the controller?
The way i have it setup in my controller is basically this:
Code:
$this->form_validation->nonce();
if ($this->form_validation->run('user_details') == TRUE) { // validation has been passed
