Symfony/Doctrine: Class is not a valid entity or mapped super class

Question

I'm getting the "Class PriceOrQuality\POQBundle\Entity\Tag is not a valid entity or mapped super class error. I've have checked all the answers to similar questions, but I cannot seem to grasp the problem. The error is thrown by my Repository Class ``` <?php namespace PriceOrQuality\POQBundle\Entity\Repository; use Doctrine\ORM\EntityRepository as ER; use PriceOrQuality\POQBundle\Entity\Tag; use Doctrine\ORM\EntityManager; /** * EntityTagsRepository * */ class EntityTagsRepository extends ER { public function getTagsForTagCloud($entity_ids = null, $tag_id = null) { $em = $this->getEntityManager(); $qb = $em->createQueryBuilder(); $qb->select(array('IDENTITY(et.tag) as id, COUNT(et.tag) as tag_id_count, LOWER(t.tag) as tag')); $qb->from('PriceOrQuality\POQBundle\Entity\EntityTag', 'et'); $qb->leftjoin('PriceOrQuality\POQBundle\Entity\Tag','t', 'WITH', 'et.tag = t.id'); $qb->groupBy('et.tag'); $qb->addOrderBy('tag_id_count','DESC'); $qb->setMaxResults(20); return $qb->getQuery() ->getRe…

Accepted Answer

Found the issue.

I had a //@todo after the meta definition and before the class definition. Apparently that screwed up the mapping, as it was not mapped in doctrine.

Moving the //@todo and rerunning the mapping fixed the problem.

For whomever finds this question with similar problems try running:

```
php app/console doctrine:mapping:info
```

It will show you if you have problems in the mapping structure in doctrine

Thanks for your time guys.
