更新:由于我没有得到任何答案,我使用一个更简单的例子重写了整篇文章.希望这有助于揭露问题.

我在表单验证方面遇到了麻烦.我可以使NotBlank()断言起作用,但Type()对我不起作用.首先,这是代码:

    /**
     * @var integer

class DefaultController extends Controller
{
    public function indexAction()
    {
        return $this->testValidation();
    }

    private function testValidation()
    {
        $item = new LineItem();

        $form = $this->createFormBuilder($item) …
