Doctrine2 using setParameters

when I seem to use parameters in my query, I get an error

> Invalid parameter number: number of bound variables does not match number of tokens

here is my code

<!-- language: lang-php -->

public function GetGeneralRatingWithUserRights($user, $thread_array)
{
$parameters = array(
'thread' => $thread_array['thread'],
'type' => '%'.$thread_array['type'].'%'
);

$dql = 'SELECT p.type,AVG(p.value)
FROM TrackerMembersBundle:Rating p
GROUP BY p.thread,p.type';

$query = $this->em->createQuery($dql)
->setParameters($parameters);

$ratings = $query->execute();

return $ratings;
}

How do I configure the parameters array properly?

thanks all for your efforts,
i used it differently using the querybuilder


$parameters = array(
'thread' => $thread_array['thread']
,'type' => $thread_array['type']
);


$qb = $this->em->createQueryBuilder();
$query = $qb
->from('TrackerMembersBundle:Rating','rating')
->select(' rating.type,
COUNT(rating.value) AS ratingcount ,
AVG(rating.value) AS ratingaverage ')
->where(
$qb->expr()->orx(
$qb->expr()->eq('rating.thread', ':thread'),
$qb->expr()->like('rating.type', ':type')
)

)
->groupBy('rating.thread,rating.type')
->setParameters($parameters)
->getQuery();

You didn't include your parameters in the query.

<!-- language: lang-php -->

$parameters = array(
'thread' => $thread_array['thread'],
'type' => '%'.$thread_array['type'].'%'
);

$dql = 'SELECT p.type,AVG(p.value)
FROM TrackerMembersBundle:Rating p
WHERE p.thread=:thread
AND type LIKE :type
GROUP BY p.thread,p.type';

$query = $this->em->createQuery($dql)
->setParameters($parameters);
