As I have seen, while starting up the ivy engine, no CLIENT_VIEW_STATE_TIMEOUT parameter is registered. By setting up the web.xml with parameter: <context-param> <param-name>org.apache.myfaces.CLIENT_VIEW_STATE_TIMEOUT</param-name> <param-value>0</param-value> </context-param> - would that prevent of a ViewExpiredException too? - for how long the View_State is stored? - why it is not registered?
