Add LswMemcache to multiple Doctrine entity manager

[odoucet]

Documentation already gives information about how to add LswMemcacheBundle support on Doctrine (see https://github.com/LeaseWeb/LswMemcacheBundle#doctrine-support)
But even if this is well handled for default entity manager, it seems it does not work for multiple entity managers :

When using executeCacheQuery() we get :
Trying to cache a query but no result driver is configured.

Another way to check :

dump($this->get('doctrine')->getManager('metrics')->
    getConnection()->getConfiguration()->getResultImpl()); 
// dump NULL

Copy of YAML :

lsw_memcache:
    pools:
        default:
            servers:
              - { host: 127.0.0.1, tcp_port: 11211 }
    doctrine:
        metadata_cache:
            pool: default
            entity_manager: [default, metrics]
            document_manager: default
        result_cache:
            pool: default
            entity_manager: [default, metrics]
            prefix: "result_"
        query_cache:
            pool: default
            entity_manager: [default, metrics]

If we try to add the cache class ourself, we end with an error :

$cache = $this->get('memcache.default');
$config = $this->get('doctrine')->getManager('metrics')->getConnection()->getConfiguration();
$config->setResultCacheImpl($cache);

This gives this error :
Argument 1 passed to Doctrine\DBAL\Configuration::setResultCacheImpl() must implement interface Doctrine\Common\Cache\Cache, instance of Lsw\MemcacheBundle\Cache\AntiDogPileMemcache given.

When you try to add the cache yourself, you should instantiate a "Lsw\MemcacheBundle\Doctrine\Cache\MemcacheCache" class and then call "setMemcache()" on the created object to set the client.

OK, updating the doc will be great about it :)

Well, we still have not figured out why "executeCacheQuery" gives an error and why it seems it does not work for multiple entity managers. Or did you find reasons for that?

[odoucet]

Not yet, And I have to admit I've changed my code after I encountered this
bug to cache the query result myself.

OK, thank you. I will try to reproduce it and update this thread.
