Simon, What exactly is "SERIALIZE_STATE_IN_SESSION=true/false" that is new in the nightly then?
As far as I can tell - the 1.1.1 release was not serializing the bean I placed in t:saveState, but it does in the nightly. So is 1.1.1 equivalent to SERIALIZE_STATE_IN_SESSION=false? Where was the state being saved then? Thanks taking time to explain - perhaps this should go to myfaces wiki?

With managed beans, the MyFaces state-handling is irrelevant; JSF doesn't try to "serialize backing beans". The beans simply go into the servlet engine's request, session or application scope as for a non-JSF application. Objects in the session don't need to be serializable, though things like clustering and hot-restart won't work if they are not. However when using t:saveState, the two worlds do meet, because that component is a UIComponent that gets stored along with the View, but it retains a reference to a managed bean that it serializes too. In this case the referenced bean *must* be Serializable (or implement StateHolder) as documented for the saveState component. Cheers, Simon
