我定义了一个具有两种可能性的 EventSubscriber，其中一种添加了一个带有可变数量按钮的单选按钮。除非选中其中一个单选按钮，否则一切似乎都按预期运行。检查后，我得到

此表单不应包含额外字段。

错误。

如何避免这种情况？

一些代码：

class AddV2FieldsSubscriber implements EventSubscriberInterface {

    private $factory;

    public function __construct(FormFactoryInterface $factory) {
        $this->factory = $factory;
    }

    public static function getSubscribedEvents() {
        return array(FormEvents::PRE_SET_DATA => 'preSetData');
    }

    public function preSetData(DataEvent $event) {
        $data = $event->getData();
        $form = $event->getForm();
        if (null === $data) {
            return;
        }
        // check if the client object is v1: id exists, dateAdded is null
        $n = $data->getMembers()->count();
        if (!$data->getId() || $data->getDateAdded()) {
            $date = new \DateTime();
            $form->add($this->factory->createNamed('dateAdded', 'date', $date, array(
                    'widget' => 'choice',

在这种情况下，答案是使用调试器找出 Symfony 确定的额外字段。原来，模板中有一些硬连线的隐藏字段需要删除。嗬！
