Symfony2: default locale not translated in prod env

Question

I have set up my website translation on Symfony2 with JMSTranslationBundle and JMSI18nRoutingBundle. The default locale is "en", and I have successfully translated text to "fr".

In dev environment, everything is working great, I get the right translations in /en and /fr pages, but in prod environment, only /fr is correctly translated. In /en pages I only see the translations names, ie text.submit.

I'm using the desc filter as default translation, so I do not have xliff files for english.

Any idea what prevents the default translation from being used in prod environment?

Btw, I have cleared the cache ;)

Answer 1

Actually, the desc filter does not seem to be used in production, I had to create an english translation xliff file.
