Controller_Template gives Creating default object from empty value

I'm building a KO3 website and I'm creating a new Controller_Template that looks like this:

<?php
defined('SYSPATH') or die('No direct script access.');

class Controller_Menu extends Contro开发者_StackOverflow社区ller_Template {

    public $template = "menu/menu";

    public function __construct() {
        $this->User = \Base\User::getLoggedInUser();
    }

    public function action_show() {
        // Do totally nothing
    }
}

No rocket science in here. In my APPPATH."/views/menu" directory I have a "menu.php" file that looks like this:

<?php
echo "foobar";

Impressive right? ;)

When I try to load http://localhost/menu/show I get the following error:

ErrorException [ Strict ]: Creating default object from empty value

SYSPATH/classes/kohana/controller/template.php [ 44 ]

45      }
46

I have similar function implemented in other controllers and they all work perfectly. So can anybody tell me what is the problem here?

EDIT I dumped the request object in the after method and it is not set, i.e. it has the value null.

I found the solution. I had to call the parent constructor in my overwritten constructor. Changing the code to:

class Controller_Menu extends Controller_Template {

    public $template = "menu/menu";

    public function before() {
        $this->User = \Base\User::getLoggedInUser();
    }

    public function action_show() {
        // Do totally nothing
    }
}

Fixed my problem.

EDIT

Changed the code to suggestions in the comments.
