How to add a translatable string ?

[tiledcode]

Hello everybody,

 

I have overriden the AdminImportController.php and added a new translatable string to it using the new method.

'attachments' => array('label' => $this->trans('Attachments (x,y,z...)', array(), 'Admin.ToSort'))

When I look at the translation tool in the B.O. neither the new string nor the new domain (Admin.ToSort) is shown.

Is there something more to do ?

 

Thanks

 

Edit : Ok, I just read that the new translation system is not supposed to be working for contributor's modules, but should it work for everything else ?
