Question

The KNP MenuBundle is a Symfony2 bundle for handling menus in a very dynamic way. The bundle comes out with a simple tutorial example, provided here.
In the proposed example, within the Builder class, the authors supposed that a function setCurrentUri() has to be called on the $menu object. However, $menu is an instance of MenuItem class, which does not implements the above mentioned function.

To make the answer self contained, I report the code of the example class provided here:

<?php
// src/Acme/DemoBundle/Menu/Builder.php
namespace Acme\DemoBundle\Menu;

use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAware;

class Builder extends ContainerAware
{
    public function mainMenu(FactoryInterface $factory, array $options)
    {
        $menu = $factory->createItem('root');
        $menu->setCurrentUri($this->container->get('request')->getRequestUri());

        $menu->addChild('Home', array('route' => 'homepage'));
        $menu->addChild('About Me', array(
            'route' => 'page_show',
            'routeParameters' => array('id' => 42)
        ));
        // ... add more children

        return $menu;
    }
}

PS: Notice that an important import is missing in this example, which I report in the following for sake of completeness:

use Symfony\Component\HttpFoundation\Request;

I am also looking for the documentation update, but as a temporary solution you can set versions in deps like these:

[KnpMenu]
    git=https://github.com/KnpLabs/KnpMenu.git
    version=v1.1.2

[KnpMenuBundle]
    git=https://github.com/KnpLabs/KnpMenuBundle.git
    target=/bundles/Knp/Bundle/MenuBundle
    version=v1.1.0
