Knp Paginator with findAll() method

Question

I have the Problem, that the knp paginator only works like this:

    $em    = $this->get('doctrine.orm.entity_manager');
    $dql   = "SELECT a FROM MainArtBundle:Art a";
    $query = $em->createQuery($dql);


    $paginator  = $this->get('knp_paginator');
    $pagination = $paginator->paginate(
        $query,
        $this->get('request')->query->get('page', 1)    /*page number*/,
        8                                        /*limit per page*/
    );

But not in this way:

    $em         = $this->getDoctrine()->getManager();
    $entities   = $em->getRepository('MainArtBundle:Art')->findAll();

    $paginator  = $this->get('knp_paginator');
    $pagination = $paginator->paginate(
        $entities,
        $this->get('request')->query->get('page', 1)    /*page number*/,
                                                      /*limit per page*/
    );

Why is it like this? I don't understand.

Here´s my twig call :

<li>{{ knp_pagination_sortable(paginator, 'Oldest', 'a.id', {'direction': 'desc'}) }}</li>

findAll() is compatible with Knp_paginator, you just have to give it to your paginator :

$query = $em->getRepository('Acme\FOOBundle\Entity\BAR')->findAll();
$paginator = $this->get('knp_paginator');
requests = $paginator->paginate(
    $query,
    $this->get('request')->query->get('page', 1), 
    5
);
