I am developing a Project using Silverstripe 3.1 beta 3. It is Multilingual, only two languages (de_DE, en_US).
For Implementing Multilingual functionality on the site I installed the Translatable Module. It is working properly on the Pages but not on DataObjects. For that purpose I tried to solve it in a way to make more fields for each Language since I have only 3 fields to be translated. It is all working properly in CMS and Frontend. To show the DataObjects in Frontend I am using the Director rules in mysite/_config/config.yml file:
Director:
rules:
'referenzen/projekte/$Kat/$RefID/$LeistungID': 'ReferenzDetailPage_Controller'
'references/projects/$Kat/$RefID/$LeistungID': 'ReferenzDetailPage_Controller'

Problem:
My problem is that in the Controller and its viewer Template I have no access on the Locale Variable to show the right Language Fields accordingly. I tried to save the Locale value on a session variable and use it to differentiate between languages but it is overwritten and shows me always the default set Language which is (de_DE).

Using Uncle Cheese Module for DataObject Translation having the same problem.

Can anyone Help please? Am I on the right path? I am relatively new to Silverstirpe. Thanks!
