我在 p:accordionpanel 的选项卡中有一个表单，因此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，但不显示 p:messages。如果验证失败，则数据未存储在数据库中，我只是没有收到消息。

支持 bean 是会话范围的。

模板中没有表单，因此没有嵌套在另一个表单中的表单。我试图在命令按钮中添加 f:ajax render="messages"，正如 BalusC 在他广受好评的 11 个问题中所建议的那样，询问命令按钮是否失败，但是命令按钮不再起作用。

谢谢你的帮助！

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

感谢 BalusC 关于更新属性的提示。

我正在使用 PrimeFaces 3.4.2
