我最近刚刚更新到 2.8，现在调用 Form Factory 的 create 函数时出现以下错误。

Error: Class Symfony\Component\Form\Extension\Core\Type\FormType contains 1 
abstract method and must therefore be declared abstract or implement the 
remaining methods (Symfony\Component\Form\FormTypeInterface::setDefaultOptions)

FormFactory 的调用如下所示：

$this->formFactory->create(
        get_class(new ProductType()),
        $product,
        [
            'method' => 'POST',
            'type' => $type,
            'locales' => $context->shop->getLocales(),
            'product' => $product,
            'numberDataTransformer' => $this->numberTransformerFactory->createFromLocale(
                $context->user->getLocale(),
                $context->shop->getDefaultLocale()
            ),
            'priceType' => $context->shop->getConfiguration()->getProductConfiguration()->getPricesBackend(),
            'isShortDescriptionEnabled' => $context->shop->getConfiguration()->getProductConfiguration()->isShortDescriptionEnabled()
        ]);

我尝试了几种方法将 ProductType 传递给函数，但似乎都没有。我总是得到两个结果之一：结果是找不到类型，或者返回 FormType 没有实现 setDefaultOptions 的错误。

我错过了什么？

编辑：

以下是一些附加代码：

formFactory参数的声明：

public function __construct(Request $request, FormFactoryInterface $formFactory)
{
    $this->request = $request;
    $this->formFactory = $formFactory;
}

问题是由根本没有更新的文件产生的。 setDefaultOptions 的实现应该仍然存在于 Symfony 2.8 类中——但他们没有。在摧毁我的流浪者并重新创建它之后，一切都很好。

但是感谢大家的帮助！
