Question

我在下面发布了我的代码。在面板属性的同时，一切正常（id = "idPanemCriticas"）closable = "false"。

如果我将其更改为true，则它不会显示更多消息，如果我关闭面板，则无法打开更多消息。我真的需要帮助，谢谢。

您是否尝试在autoUpdate="true"中使用p:outputPanel属性？ p:outputPanel的目标是允许您not to include an element in you element tree。在您的情况下，您的嵌入式p:panel和p:messages将始终呈现，因此我没有看到使用p:outputPanel来实现这一点。

如何打开一个属性可关闭的面板真的？
