I have recently upgraded my WebApp to MyFaces 2.1.15 and after that I am
experiencing the below error,
java.lang.NullPointerException: null values not allowed

I have set the following in web.xml file,
org.apache.myfaces.CACHE_OLD_VIEWS_IN_SESSION_MODE = hard-soft
org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION = 30,
org.apache.myfaces.SERIALIZE_STATE_IN_SESSION= false,
javax.faces.STATE_SAVING_METHOD = false
I have checked similar issue in earlier version too,
https://issues.apache.org/jira/browse/MYFACES-1296
but this seems to be little different from the exception stack.
Please look into it since it seems to be an issue with the version 2.1.15
