Symfony2.8项目通过注释NOT YML进行子表单验证没有实体或学说参与

主窗体通过注释确认。收集字段，子表单无法验证。无论您输入什么内容，当主表单字段有效时，子表单中的每个字段都将作为有效字段传递。

我在网上尝试了很多建议，

＆＃39; error_bubbling＆＃39;，＆＃39; cascade_validation＆＃39;以及@Valid（）标记。什么都行不通。

我已将var_dump（...）添加到symfony2代码库中的RangeValidator类，并且未创建/调用它。为了证明它没有被使用，我将一个子表单字段复制到主表单，然后调用框架的验证程序进行范围检查，它应该对子表单中的某些字段执行，而不是。

显然有更多的代码，包括客户端javascript，但下面是一个基本的代码片段（从我的代码中挖出了这个问题）：

Main form:

class SubsetAdd extends AbstractType
{
    /**
     * @var string
     *
     * @Assert\NotBlank(
     *        message="Subset name should not be blank"
     * )
     * @Assert\Regex(
     *        pattern="/^[\w\s\d\:\_\-\+]{1,64}$/",
     *        message="Subset name should contain ..."
     * )
     */
    protected $subsetName;


    /**
     * @var string
     *
     * @Assert\Regex(
     *        pattern="/^[\d]{1,4}[Kk]{1}$/",
     *        message="Baud rate should be <n>K"

    /**

Basic controller:

class SubsetsController extends Controller
{
    ...

    /**
     * @Route("/add", name="subsets-add")
     * @Method({"GET","POST"})
     */
    public function addFormAction(Request $request)
    {
        $subsetAdd=new ModuleForm\SubsetAdd();

        $options=array(
            'submit'=>false,
        );
        $form = $this->createForm(ModuleForm\SubsetAdd::class, $subsetAdd, $options);

        $form->handleRequest($request);

        if ($form->isSubmitted()) {        
            var_dump('Submitted');
            if ($form->isValid()) {
                var_dump('Valid');

                var_dump("<pre>");
                var_dump($subsetAdd->getEntries());
                var_dump("</pre>");
            }
        }

        return $this->render("SerialBundle:Subsets/form.subsets.html.twig', array(
            'anyerrors' => (($form->isSubmitted() && !$form->isValid())?true:false),
            'form' => $form->createView(),    // invoked after handlerequest
        ));
    }
}

如何使用'constraints'=＆gt;新的有效（）？

 $builder->add('entries', Type\CollectionType::class, array(
        'constraints' => new Valid(),
        'label' => 'Entries',
        'type' => Module\EntryType::class,
        'allow_add' => true,
        'allow_delete' => true,
        'required' => true,
        'prototype' => true,
        'prototype_name' => 'entries__name__',
  ));
