Integrate Smarty Template Parsing into CodeIgniter

[eluser]Abel A.[/eluser]
I think I found a bug: You can't load a view outside the CI_Controller class. Example:

Code:

class Core {

public $CI;

public function __construct()
{
  $this->CI =& get_instance();
}

public function msg($msg)
{
  $this->CI->load->helper('url');
  
  //if (strlen($msg->location) > 1) header("Refresh:3;url=".base_url().$msg->location);
  
  $assgin_data = array("msg"=>$msg);
  $this->CI->load->view('pos_msg',$assgin_data);
  exit;
}
}

In theory when $this->core->msg($msg) is called within a controller, the view should be loaded from the msg function. Is this a bug? or am I using CI improperly?
