This solution is not compatible with DoctrineMongoDBBundle. In fact the Proxy files are searched under ORM, which should be ODM:

The proxy file "/var/www/project/app/cache/dev/doctrine/orm/Proxies/__CG__\Project\CustomerBundle\Document\Customer.php" does not exist. If you still have objects serialized in the session, you need to clear the session manually.

Any solutions ????
