Codeigniter extend form validation not working

Question

For the past hours I have tried to extend the form validation library in Codeigniter 2.2.0 with a rule, but it does not seem to get it at all? It just continues, like the rule doesn not exist at all.

My extension of the form validation is located in application/libraries and is named MY_Form_validation.php.

The file contains the following code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Form_validation extends CI_Form_validation
{
    public function run($module = '', $group = '')
    {
        (is_object($module)) AND $this->CI =& $module;
        return parent::run($group);
    }

    public function price_validation($str)
    {
        if (!preg_match('/^\d+(?:\,\d{1,2})?$/', $str))
        {
            $this->CI->form_validation->set_message('price_validation', 'Feltet %s må kun indeholde tal, ét komma og to decimaler.');
            return FALSE;
        }
        else
        {
            return TRUE;
        }
    }
}
/* End of file MY_Form_validation.php */
/* Location: ./application/libraries/MY_Form_validation.php */

What am I doing wrong?

I found out that I have made an typo in the filename. Which I thought I have checked out. Not a proud moment.
