推荐答案
[已解决]
花了几天的时间来诊断这个问题，但最终我能够解决这个问题.
It took days to diagnose this problem, but finally I am able to solve this problem.
它实际上是@ViewScoped，它具有一个未序列化的托管属性DAO对象.因此，在渲染视图之后，facelets也会产生此异常，但是JSF视图已经渲染，这就是显示此异常的原因.
It was actually @ViewScoped and it has a managed property DAO object which was not serialized. So after view is rendered, facelets also produce this exception, but JSF view already rendered and that's why this exception showed.
解决方案:将所有序列化的对象放在@ViewScoped bean中，并标记未进行序列化的瞬态"，就像我在JSF @ViewScoped中是DAO对象一样.
Solution: Make all objects serialized in @ViewScoped bean, and mark "transient" who are not serialized like in my case it was DAO object in JSF @ViewScoped.
