accordianpanel选项卡内的表单不会生成验证消息，但命令按钮的工作方式不同

Question

我在p:accordionpanel的选项卡中有一个表单，所以每个选项卡都有自己的表单和命令按钮。命令按钮工作正常，但是不显示p:消息。如果验证失败，数据不存储在数据库中，我只是没有得到消息。

支持bean是会话作用域。

模板中没有表单，因此没有表单嵌套在另一个表单中。我曾尝试在命令按钮中添加f:ajax render="messages"，正如BalusC在他的11个问题中建议的那样，询问命令按钮是否失败，但随后命令按钮不再工作。

谢谢你的帮助!

Answer 1

在p:commandButton中添加update="@parent"解决了这个问题。

感谢BalusC关于update属性的提示。

我使用的是PrimeFaces 3.4.2
