翻译仅在symfony2中使用下划线代码（即：es_ES）

Question

I'm developing a site with Symfony2 v.2.5.0-dev and i'm trying to internationalize it.

It works fine in english (mysite.com/en/) and french (mysite.com/fr/) but for catalan and spanish only works with URLs like mysite.com/ca_ES/ and mysite.com/es_ES/ but I need to use the short language codes: ca and es.

The default language is Catalan.

I've created 4 files in src/MyProject/MyBundle/Resources/translations with name:

• messages.ca.yml
• messages.es.yml
• messages.en.yml
• messages.fr.yml

And enabled the translator:

#app/config/config.yml
framework:
    translator:      { fallback: ca }
    default_locale:  %locale%


#app/config/parameters.yml
parameters:
   ...
   locale: ca

I'd made before some other projects in Symfony2 v.2.3.x without this problem.

What I'm doing wrong?

I solved the problem by clearing the Symfony cache.
