Container null in controllers

[joseadame]

Since I've installed this bundle I have an error with fosuserBundle when trying to access:

if ($this->container->has('templating')) {
return $this->container->get('templating')->renderResponse($view, $parameters, $response);
}

container is null.

I know that they are independent bundles, but I don't know if LexikCurrencyBundle update any symfony library and change de depedency injection.

Could anybody help me?
