Symfony Paginator @Enum bug

Question

I am trying to add pagination on demand using Doctrine and the Doctrine Paginator class:

    $qb = $this->_em->createQueryBuilder();
    $qb->select(array('a.id'))
            ->from('MyProjectBundle:Account', 'a')
            ->leftjoin('a.first', 'fd')
            ->leftjoin('a.second', 'fr')
            ->where('a != ?1')
            ->setParameters(array(1 => $account))
            ->setFirstResult(($page-1) * $per_page)
            ->setMaxResults($per_page);

And as in the documentation for Paginator, I do:

return new Paginator($qb);

I have this error:

{

    "code": 500,
    "message": "[Semantical Error] The annotation \"@Enum\" in property Doctrine\\ORM\\Mapping\\GeneratedValue::$strategy was never imported. Did you maybe forget to add a \"use\" statement for this annotation?"

}

I turn it on use Doctrine\ORM\Tools\Pagination\Paginator;and I don’t know why I have this error?
