我正在使用 Primefaces3.5 和 Jsf2.1.9 我遇到了一个奇怪的问题

 <p:commandButton>

也

 <p:commandLink>

我必须按下按钮并链接多个，然后 JSF bean 方法正在调用，否则单击没有发生当我阅读一些Stackoverflow问题时，此问题与JSF相关，但即使将 Primfaces3.5 与他们的组件一起使用，我也遇到了这个问题。任何人都知道我该如何解决这个问题。我的 JSF 页面

基本上这不是奇怪的问题在第一次单击时，jsf 首先查看是否有 (javax.faces.ViewState) 状态可用，如果它不可用，那么它会为你创建一个 & 当你第二次单击时，因为 Jsf 状态可用它调用 bean 方法。解决方案：尝试通过javascript函数创建jsf状态

感谢primefaces 的Çağatay Çivici项目负责人。他建议我

然后尝试使用 2.1.17，showcase 是 2.1.17。

所以我为 jsf 更新了我的 pom，它就像一个魅力。

谢谢
