调用handleRequest或bind时找不到Silex ExecutionContext :: getValidator()

Question

我有以下silex代码在完成时呈现一个简单的表单和消息:

$app->register(new Silex\Provider\FormServiceProvider\FormServiceProvider());
$app->register(new Silex\Provider\ValidatorServiceProvider());

$app->match('/contact', function(Request $request) use ($app) {

$form = $app['form.factory']->createBuilder('form', null)
    ->add('name', 'text', array('required' => true, 'label' => 'Name',))
    ->add('submit', 'submit')
    ->getForm();

$form->handleRequest($request);

if ($form->isValid()) {

    die('success);
}

    return $app['twig']->render('contact.html.twig', array(
        'form'   => $form->createView(),
));

但是在表单提交时,我会收到错误消息:

Call to undefined method Symfony\\Component\\Validator\\ExecutionContext::getValidator() 
in /home/user/project/vendor/symfony/form/Symfony
/Component/Form/Extension/Validator/Constraints/FormValidator.php on line 56

我正在注册上面的ValidatorServiceProvider,所以我很难理解它可能是什么.

Answer 1

它看起来像是一个Symfony bug.向后移植这个提交为我修复了它.
