I\'m using a class form in Symfony2 Beta3 as follows:
namespace Partners\\FrontendBundle\\Form;
use Symfony\\Component\\Form\\AbstractType;
use Symfony\\Com
CptSadface's answer was what helped me with translating my entity choices.
$builder
->add(
'authorizationRoles',
null,
[
'label' => 'app.user.fields.authorization_roles',
'multiple' => true,
'choice_label' => 'name', // entity field storing your translation key
'choice_translation_domain' => 'messages',
]
);
