Jsf java.lang.ClassCastException:javax.faces.component.StateHolderSaver不能强制转换为[Ljava.lang.Object；

我在我的xhtml页面中显示带有链接的项目列表。当我从该链接中单击“返回上一页”按钮时，我基本上重置了bean中的标志，以指示xhtml显示哪个页面，并从数据库中重新加载链接列表

当我单击此新页面中的同一链接（或任何其他相关链接）时，会出现以下错误：

如果我刷新页面并重试，则不会出现问题。有人知道我做错了什么吗

----编辑----

为了防止其他使用liferay的人遇到这个问题，我刚刚在pom.xml中添加了这些行，现在一切正常：）非常感谢BaluC

com.sun.faces
jsf impl

编译

这是一个已知的Mojarra问题，已在Mojarra 2.1.12中修复

因此，只需将JSF库升级到至少Mojarra 2.1.12就可以了。它目前已经达到2.1.26，与2.1.12相比，有更多与状态管理相关的修复程序
