Symfony 2.1 FOSUser translate error messages - symfony

Question

I am using the following code to get all the errors in a form:
// get all the errors in the form in an array
public static function getErrorMessages(\Symfony\Component\Form\Form $form) {
$errors = array();
// actual errors
foreach ($form->getErrors() as $key => $error) {
$errors[] = $error->getMessage();
}
// find children that are not valid
if ($form->count()>0) {
foreach ($form->all() as $child) {
if (!$child->isValid()) {
$errors[$child->getName()] = formHelper::getErrorMessages($child);
}
}
}
That works. The only issue is for FOSUser: I've defined my validation group and the errors aren't getting translated. Instead of getting "The password is too short" I am getting "fos_user.password.short". The issue is with the line:
$errors[] = $error->getMessage();
That does not translate the error. Anybody could help me out figure out this issue?

You should use translator service to translate messages
Try this:
public function getFormErrorsAssoc(FormInterface $form) {
$errors = array();
/* #var \Symfony\Component\Form\FormError $error*/
foreach ($form->getErrors() as $key => $error) {
$message = $this->translator->trans($error->getMessageTemplate(), $error->getMessageParameters(), 'validators');
if ($message) {
$errors[$key] = $message;
}
}
if ($form->hasChildren()) {
/* #var FormInterface $child*/
foreach ($form->getChildren() as $child) {
$label = $child->getAttribute('label') ? : $child->getName();
if (!$child->isValid()) {
$errors[$label] = $this->getFormErrorsAssoc($child);
}
}
}
return $errors;
}
