Symfony2：默认表单类型猜测器损坏

Question

我以某种方式设法破解了 symfony 2.6 的默认表单类型猜测器。让我向您展示一些简单的代码：

ExampleType.php

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class ExampleType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('test')  // should be a text type because it's stored as string
        ;
    }

    ...

}

但是当我调用表单时，我得到了一个未捕获的 PHP 异常：

Symfony\Component\Form\Exception\InvalidArgumentException: "Could not load type "Symfony\Component\Form\Extension\Core\Type\TextType"" at /home/gv/PhpstormProjects/vcb/vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php line 83

堆栈跟踪：

    in /home/gv/PhpstormProjects/vcb/vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php line 83

    in /home/gv/PhpstormProjects/vcb/vendor/symfony/symfony/src/Symfony/Component/Form/FormBuilder.php line 215

at Symfony\Component\Form\FormBuilder->getForm()
    in /home/gv/PhpstormProjects/vcb/vendor/symfony/symfony/src/Symfony/Component/Form/FormFactory.php line 39

通过显式传递表单类型作为第二个参数（在本例中 'text'）来规避此异常是没有问题的，但我想知道什么可以阻止默认表单类型猜测器正常工作。

有什么建议吗？

好吧，毕竟我不知道我是怎么搞混的，但是 clearing composer cache 在重新安装 symfony 2.6 之前确实修复了它。
