Symfony的2.3事件監聽錯誤

Question

我想提交FormType設置按鈕的FormType事件監聽器裏，但是當我這樣做，我得到這個錯誤：

選項auto_initialize不存在。已知的選項有：attr，block_name，disabled，label，translation_domain

如果我設置了事件監聽它的作品的。有人能幫我嗎？

class ClientType extends AbstractType 
{ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 

     $builder 
      ->add('enquirer', new ContactType(), array(
       "by_reference" => true, 
       "required" => true, 
       'validation_groups' => array('required'), 
       'details_field' => true, 
      )) 
      [...] 

     ; 
     $builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event) { 
      $client=$event->getData(); 
      $form=$event->getForm(); 
      if($client && !$client->getId()){ 
       $form->add("createBtn", "submit", array("label"=>"Create", "attr"=>array("class"=> "btn btn-primary"))); 
      } else { 
       $form->add("saveBtn", "submit", array("label"=>"Save", "attr"=>array("class"=> "btn btn-primary"))); 
      } 
     }); 
    } 

    public function setDefaultOptions(OptionsResolverInterface $resolver) 
    { 
     $resolver->setDefaults(array(
      'data_class' => 'Sme\ClientBundle\Entity\Client', 
     )); 
    } 

    public function getName() 
    { 
     return 'client_form'; 
    } 
} 

堆棧跟蹤： 我沒有設置 「auto_initialize」，但裏面FormFactory它。有任何想法嗎？

看着\供應商\ symfony的\ symfony中的\ src \的Symfony \分量\表格\ form.php的我發現代碼：

public function add($child, $type = null, array $options = array()) 
{ 
[...] 
if (!$child instanceof FormInterface) { 
      if (!is_string($child) && !is_int($child)) { 
       throw new UnexpectedTypeException($child, 'string, integer or Symfony\Component\Form\FormInterface'); 
      } 

      if (null !== $type && !is_string($type) && !$type instanceof FormTypeInterface) { 
       throw new UnexpectedTypeException($type, 'string or Symfony\Component\Form\FormTypeInterface'); 
      } 

      // Never initialize child forms automatically 
      $options['auto_initialize'] = false; 

      if (null === $type) { 
       $child = $this->config->getFormFactory()->createForProperty($this->config->getDataClass(), $child, null, $options); 
      } else { 
       $child = $this->config->getFormFactory()->createNamed($child, $type, null, $options); 
      } 
     } elseif ($child->getConfig()->getAutoInitialize()) { 
      throw new RuntimeException(sprintf(
       'Automatic initialization is only supported on root forms. You '. 
       'should set the "auto_initialize" option to false on the field "%s".', 
       $child->getName() 
      )); 
     } 
[...] 
} 

現在我更困惑。

感謝您

嘗試升級到最新版本（目前2.3.6）。看來這個bug是2.3.4中的fixed。
