MongoDB ODM Param Converter service

In order to get the Param Converter annotation to work with the doctrine ODM you must register a service that enables the ODM registry manager.

You just have to register a service like this:

my_bundle.converter.doctrine.mongodb:
    class: Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter
    arguments: [@doctrine_mongodb]
    tags:
        - { name: request.param_converter }
