Solved! ViewExpiredException when i use @ViewScoped Added the following config in web.xml.

<context-param>
    <param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
    <param-value>false</param-value>
</context-param>

As an alternative answer, I got this exception when accidentally two different element's id were same. After giving unique id it worked well.
