rails internationalization problem

Hi,

It looks like its as easy as pie BUT, well I’m im sort of a noob in rails right now and I’m following this tutorial

http://guides.rubyonrails.org/i18n.html

it told me to work with a simple helloworld appliction. a simple index file and so on

So i followed the tutorial, added a yml file for a mock locale and added translation for it in the file

es.yml in config/locales/ directory

everything is all set up and start the server and put in the url

http://localhost:3000/hello?locale=es

and what it does is, that it shows me the content for “default” locale instead of the content in es.yml i just created

if however, I delete or remane es.yml file. the server gives error. file not found

which means the URL IS being routed to translated text BUT its still picking up the default locale content

:S
