Hi Simon,
Thanks very much, I added this code to my web.xml
<context-param>
<param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
<param-value>false</param-value>
</context-param>
but still gives the same error.
Just a thought, if it is a Serialization Error why does it not
gives an Exception when trying to serialize and only when trying
to de-serialize ?
Thanks again
