CDbMessageSource AND system messages translated.

Is it possible to use CDbMessageSource and still have system/framework messages translated?

I have to go through the painful process of manually translating all form-validation errors…

OK,that explains everything.Framework messages were being translated OK until I switched from language=>‘el’,to ‘el_GR’.

(Greek).I did that in order to localize a facebook Extension which read the language application parameter in this form el_GR.

I have done all this unnecessary translation.But why?el_GR should not confuse the system translation,it;s more specific and accurate…

Thanks a lot for your reply,I am interested in behavior.
