Another disappearing session bug?

[eluser]Stoney[/eluser]
Try this:

Code:

class MY_Session extends CI_Session {

    protected $_CI;

/*
* Do not update an existing session on ajax calls
*
* @access    public
* @return    void
*/
function sess_update() {

    $this->_CI =& get_instance();

        if ( !$this->_CI->input->is_ajax_request() ){
            parent::sess_update();
       }
   }
}
