404_override doesn't work as expected..

[eluser]thePiet[/eluser]
I'm suffering the same issue here.

application/routes.php:

Code:

$route['404_override'] = 'error/not_found';

application/controllers/error.php:

Code:

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

class Error extends CI_Controller {

    function __construct()
    {
        parent::__construct();
    }

    *snip*

    function not_found()
    {
        $this->breadcrumb->append('Pagina niet gevonden');

        $this->load->view('header');
        $this->load->view('error/not_found');
        $this->load->view('footer');
    }
}

As you can see I'm using a breadcrumb class to handle breadcrumbs. But this happens when throwing the 404 error:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Error::$breadcrumb
Filename: controllers/error.php
Line Number: 30

Fatal error: Call to a member function append() on a non-object in application/controllers/error.php on line 30

So it looks like libraries that are auto-loaded, aren't loaded anymore or something. Manually loading the libraries in the controller doesn't affect the error.

In short, it isn't possible to use other libraries / helpers / plugins within the 404_override route.
