I have to implement my own translation loader. I\'ve used the tutorial on:

http://blog.elendev.com/page/3/#post-26 or http://blog.elendev.com/development/php/symfony/use-a-database-as-translation-provider-in-symfony-2/
Another issue here is that there are no LanguageRepository class in the example. You can use this example.
