Symfony2: JavaScript doesn't work on Prod environment

Question

In Dev enviroment it works perfectly, but when I switch to Prod it doesn't do anything. It looks like it doesn't attach the event listeners (when I inspect elements with Chrome, no event listener is detected where they should). Any ideas? I've cleared both caches and maybe it's important to say that I had copied

_assetic:
resource: .
type:     assetic

from routing_dev.yml to routing.yml because if I don't I got the following 500 Internal Server Error:

request.CRITICAL: Twig_Error_Runtime: An exception has been thrown during the rendering of a template ("Route "_assetic_f582f37" does not exist.")

Answer 1

Have you dumped your asset files?

php app/console assetic:dump --env=prod --no-debug
