Using the trait \Knp\DoctrineBehaviors\Model\Translatable\Translation inside an Entity, I see that the property currentLocale is never setted , so we always obtain the default locale ('en') in all the calls to $this->translate().

If I change this getDefaultLocale, all the translations are made correctly, so I think that is no problem with the fallback.

I tried debug the currentLocaleCallable. I see that if I put a "var_dump ($this->container->get('request'));" in the contructor of currentLocaleCallable, the request have a locale to null. And outside the request has the correct locale.It seems that container is not in the scope: request , i don't know how can I get it to work

I post an issue in github https://github.com/KnpLabs/DoctrineBehaviors/issues/71

EDITED

This service is defined in vendor/knplabs/doctrine-behaviors/config/orm-services.yml and is:

    public:  false

        - "%knp.doctrine_behaviors.reflection.is_recursive%"
        - "@knp.doctrine_behaviors.translatable_listener.current_locale_callable"
    tags:
        - { name: doctrine.event_subscriber }
