Form collection with translations throw FatalError on GedmoTranslationMapper

Hi,

when I try to save a form with one collection of another entity with translations, the GedmoTranslationMapper throws this error: 

FatalErrorException: Error: Call to a member function filter() on a non-object in /vendor/a2lix/translation-form-bundle/A2lix/TranslationFormBundle/Form/DataMapper/GedmoTranslationMapper.php line 67,

because the $data variable is a empty array.

This error appears on execute $form->bind($request);
The $request is ok with all data sent correctly

before update to symfony 2.3 and update your bundle everything worked correctly.

this is a bug of new version? or a bad implementation of this bundle?

Thank's!
