Get Translated Form Error Messages (Symfony2.3)

My version of solving the problem:
/src/Intranet/OrgunitBundle/Resources/config/services.yml

services:
    form_errors:
        class: Intranet\OrgunitBundle\Form\FormErrors

/src/Intranet/OrgunitBundle/Form/FormErrors.php

<?php
namespace Intranet\OrgunitBundle\Form;

class FormErrors
{
    public function getArray(\Symfony\Component\Form\Form $form)
    {
        return $this->getErrors($form);
    }

    private function getErrors($form)
    {
        $errors = array();

        if ($form instanceof \Symfony\Component\Form\Form) {

            // соберем ошибки элемента
            foreach ($form->getErrors() as $error) {

                $errors[] = $error->getMessage();
            }

            // пробежимся под дочерним элементам
            foreach ($form->all() as $key => $child) {
                /** @var $child \Symfony\Component\Form\Form */
                if ($err = $this->getErrors($child)) {
                    $errors[$key] = $err;
                }
            }
        }

        return $errors;
    }
}

/src/Intranet/OrgunitBundle/Controller/DefaultController.php

$form = $this->createFormBuilder($entity)->getForm();
$form_errors = $this->get('form_errors')->getArray($form);
return new JsonResponse($form_errors);

Я бы немного ещё добавил

   foreach ($form->all() as $key => $child) {
        if($child instanceof \Symfony\Component\Form\Form){
            if ($err = $this->childErrors($child)) {
                $errors[$key] = $err;
            }
        }
    }

Т.к. иногда SubmitButton тоже уже есть в форме

Что в принципе решено во 2 варианте ))

Korpch's function seems to be broken. Did not work as expected for me.

yapro's version worked, but was missing translation. Also it generated an array of arrays, which is not what i expected to get. I was looking for a way to get a simple plain list of error messages to display them to the user.

My final version:

     /**
     * @param \Symfony\Component\Form\Form $form
     * @return string[]
     */
    public static function getFormErrors(\Symfony\Component\Form\Form $form)
    {
        $errors = array();

        if ($form instanceof \Symfony\Component\Form\Form) {
            // find errors of this element
            foreach ($form->getErrors() as $error) {
                $errors[] = self::$translator->trans($error->getMessage(), array(), 'validators');
            }

            // iterate over errors of all children
            foreach ($form->all() as $key => $child) {
                if($child instanceof \Symfony\Component\Form\Form) {
                    /** @var $child \Symfony\Component\Form\Form */
                    $err = self::getFormErrors($child);
                    if (count($err) > 0) {
                        $errors = array_merge($errors, $err);
                    }
                }
            }
        }

        return $errors;
    }
