Symfony2 KNP Pagination "Cannot count query " - php

Question

So , i'm working on a news portal . I'm using KNP Paginator,and i've got an error :
Cannot count query which selects two FROM components, cannot make distinction
And now , my source code :
#block of code from controller
$rep = $this->getDoctrine()->getRepository('NickCoreBundle:News');
$user = $this->get('security.context')->getToken()->getUser();
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$rep->getNewsFeedQuery($user->getId()),
$page,
10
);
and from my repository:
public function getNewsFeedQuery($userid)
{
$userid = intval($userid);
return $this->getEntityManager()->createQueryBuilder()
->select('n')
->from('NickCoreBundle:News', 'n')
->innerJoin('NickCoreBundle:Subscriptions', 's', 'WITH', 's.user = :userid AND n.source = s.source')
->orderBy("n.date","DESC")
->setParameter('userid', $userid)->getQuery();
}
how to solve it :) ? tried to get result from query , in ArrayCollection , it works (partialy,not sorted by date , and i think this method used a lot of time)

It's a little late to answer but it could be of help to other readers.
I would suggest doing away with the explicit innerJoin and let Doctrine handle the joins.
return $this->getEntityManager()->createQueryBuilder()
->select('n')
->from('NickCoreBundle:News', 'n')
->join('n.source', 's')
->where('s.user'= :userid )
->orderBy("n.date","DESC")
->setParameter('userid', $userid)->getQuery();
