Based on this documentation, I've implemented a catch all route which routes to an error page.

Here is the last route in my bootstrap.php

Route::set('default', '<path>', array('path' => '.+'))
    ->defaults(array(
        'controller' => 'errors',
        'action'     => '404',
    ));

However I keep getting this exception thrown when I try and go to a non existent page

Kohana_Exception [ 0 ]: Required route parameter not passed: path

If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just seems to load the home route, which is...

Route::set('home', '')
    ->defaults(array(
        'controller' => 'home',
        'action'     => 'index',
    ));

The home route is defined first.

I execute my main request like so

$request = Request::instance();


try {

    // Attempt to execute the response
    $request->execute();

} catch (Exception $e) {


   if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e;

    // Log the error
    Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e));

    // Create a 404 response
    $request->status = 404;
    $request->response = Request::factory(Route::get('default')->uri())->execute();

}

$request->send_headers();
echo $request->response;

This means that the 404 header is sent to the browser, but I assumed by sending the request to the capture all route then it should show the 404 error set up in my errors controller.

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

class Controller_Errors extends Controller_Base {

    public function before() {
        parent::before();
    }

    public function action_404() {


        $this->bodyClass[] = '404';

        $this->internalView = View::factory('internal/not_found');

        $longTitle = 'Page Not Found';

        $this->titlePrefix = $longTitle;


    }
}

Why won't it show my 404 error page?
