Another Codeigniter Property Undefined issue

Question

I'm getting this, but I don't understand why.:

A PHP Error was encountered

Severity: Notice
Message: Undefined property: Menu::$menu_model
Filename: controllers/menu.php
Line Number: 16


Fatal error: Call to a member function get_menu() on a non-object in /home/.../modules/menu/controllers/menu.php on line 16

I've looked at this, that and the other. But even with my simple code, it still breaks.

The Controller

class Menu extends CI_Controller
{
    /**
     * Constructor method
     */
    public function __construct()
    {
        parent::__construct();
    }

    function index($layout = -1)
    {
        $this->load->model('menu_model');
        // There is no $this->menu_model at this point. If I echo it out, it says property undefined as well.
        $data['menu'] = $this->menu_model->get_menu($layout);  // It fails on this line.
        $data['thisurl'] = $this->uri->uri_string();
        $this->load->view('menu.php');
    }

}

The Model

class Menu_model extends CI_Model 
{
    public function get_menu($layout = -1)
    {
        $menu = array(
            0 => array('href' => '/', 'label' => 'Home', FALSE),
            1 => array('href' => '/about', 'label' => 'About', FALSE),
            2 => array('href' => '/help', 'label' => 'Help', FALSE)
        );

        return $menu;
    }
}

The file is loaded successfully. If I change the class name to Menu_model_fail... I get an error, and if I change the load->model('menu_model_break') I also get an error. So I know it's loading the file correctly.

It looks like you are using the MX modular extension - what happens if you change your controller to extend from MX_Controller instead of CI_Controller? — Darrrrrren, Nov 09 '12 at 18:27
subtle side note - what's the point of passing $layout if you don't use it? — Kai Qing, Nov 09 '12 at 18:27
I will, not there yet. I got stuck on the model not loading. — Recognizer, Nov 09 '12 at 18:31
@Darrrrrren if you post that as an answer, I'll accept. That was it. — Recognizer, Nov 09 '12 at 18:32

say, out of curiosity what indicated this was using the MX modular extension? – Kai Qing Nov 09 '12 at 18:34
@KaiQing `/modules/` was referenced in the error path output. – Darrrrrren Nov 09 '12 at 18:35
aah good catch. I've worked on tons of CI projects but not many that used modules. I didn't even see that. – Kai Qing Nov 09 '12 at 18:36
Cheers :-) I pretty much only use CI with the modular extension - makes it so much easier to organize larger apps. – Darrrrrren Nov 09 '12 at 18:36
