无论我做什么,我都会得到 javax.faces.application.ViewExpiredException: viewId。我知道如何处理异常(如果出现错误,请再次重定向到主页),问题是我从 commandButton 调用的任何操作都没有执行。
基本上我有一个带有操作的commandButton 的简单视图。我按下它并得到viewExpiredException,或者如果我处理错误,我没有收到错误消息,但我的commandButton 仍然不起作用。
我试着添加这个:
<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>client</param-value>
</context-param>
但它不起作用。我不知道发生了什么事。。
这是我的看法:

我需要知道为什么会发生这种情况,而不是如何处理异常。我无法从 commandButton 调用任何操作,因为没有任何反应。
