Knp menu bundle warnings after update to symfony 2.3

Question

After updating symfony from 2.2 to 2.3, i've got new stange errors on all my pages and in my scripts:

Deprecated: Knp\\Menu\\Silex\\Voter\\RouteVoter is deprecated because of namespace, use Knp\\Menu\\Matcher\\Voter\\RouteVoter instead. in \\vendor\\knplabs\\knp-menu\\src\\Knp\\Menu\\Silex\\Voter\\RouteVoter.php on line 20

and

Deprecated: Knp\\Menu\\Silex\\RoutingExtension is deprecated, use Knp\\Menu\\Integration\\Symfony\\RoutingExtension instead. in \\vendor\\knplabs\\knp-menu\\src\\Knp\\Menu\\Silex\\RoutingExtension.php on line 15

How could I fix this ? I don't find the answer on the web.
Thank you in advance

use Knp\Menu\MenuFactory;

use Symfony\Component\DependencyInjection\ContainerAware;

class Builder extends ContainerAware
{
    public function mainMenu(MenuFactory $factory, array $options)
    {
        $menu = $factory->createItem('root');

        $menu->addChild('Dashboard', array(
                        'route' => 'dashboard' )); 
        $menu->addChild('Color Scheme', array(
                        'uri' => 'slidescheme' ));
        $menu->addChild('Questionnnaires', array(
                        'uri' => 'questionnaire_manage' ));
        // ... add more children

        return $menu;
    }
}

Answer 1

It's not a good idea update your symfony version in the middle of a develpment. Actually, it's a bad idea upgrade any bundle you are using in your code (there's always exceptions, but this is the general rule).

In your case, the bundle has been refactored in this new version, so now it's not compatible with the code you have written . I'm afraid you only have two alternatives:

• Adapt your code to the new requirements
• Or change your composer again to use symfony 2.2 and run composer update

I strongly suggest the second option if you already have many lines of code written.

Answer 2

The issue is that you're using a dev version of knplabs/menu. Edit your composer file from:

"knplabs/knp-menu-bundle":               "dev-master",

to:

"knplabs/knp-menu-bundle" :               "~1.1",

and the error message will go away. Note that if you're actually using dev features of knplabs/menu (like Matcher and Voter ) those won't be available any more. But Symfony does not require them anyway.
