Symfony2.3：未呈现验证错误

Question

联系表单指定一组家庭的日期、类型和配送中心。 [家庭集被定义为该中心的最新家庭，并通过 ajax 呈现。] 类型实体是必需的，日期不得为将来。类型约束在 Contact 实体中指定；日期约束在自定义验证器中。如果违反了这些约束中的任何一个，则该表单在 Netbeans 调试中确认为无效。此外，错误消息出现在 Netbeans 中。然而，模板中都没有出现任何约束消息。将 form_errors 转储添加到模板中没有任何作用。我无法确定为什么没有消息出现。

Answer 1

错误是由于包含代码

'error_bubbling' => true,

由于表单不是子表单，因此没有理由让该代码存在。它是来自应用程序早期版本的工件。
