MappingException: Class Namespace\Entity is not a valid entity or mapped super class.

[getme]

This happens when entity uses ORM alias

like this

<?php
namespace Namespace;

use Doctrine\ORM\Mapping as ORM;

/**
 * Enttity
 * 
 * @ORM\Entity(repositoryClass="Namespace\Entity")
 * @ORM\Table(name="table")
 */
class Entity
{
...
}

is it possible to fix this?

Have you read the Doctrine2 documentation and/or the Symfony2 book?
The entity class is not the repository class.
I suggest reading this:
http://symfony.com/doc/current/book/doctrine.html#custom-repository-classes

Hi @itavero
I'm not sure I understand you answer, can you explain?

I have fixed it already though

AnnotationRegistry::registerFile($app['db.orm.class_path'].'/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php');

            $reader = new FileCacheReader(
                    new AnnotationReader(),
                    $app['em.cache_dir'].'/annotation',
                    $app['debug']
            );
            $driver = new \Doctrine\ORM\Mapping\Driver\AnnotationDriver($reader, $app['em.entity_dirs']);

In you're example you're telling Doctrine 2 to use your Entity class as the Repository class for that Entity. Just pointing out that that's probably not what you want.

I see what you mean, that's just an example please ignore, repositoryClass is obviously diffrent ) Thanks
