Here's a couple of things you can try
-- Use a real logger instead of a Systemout.println to be sure it's
getting into the logs, and log at "error" level or higher.
- Try using t:saveState on a property of a managed bean instead of the
bean itself. I don't think it would matter, but it's a simple thing
to try. For space considerations, I never save a managed bean -- I
only save select properties of the bean.
<t:saveState id="idSaveVideo" value="#{videoHolder.video}"/>

I only have a System.out.printlin in my readObject, writeObject. I have
checked all tomcat logs and can not see/find
the print statements.
saveState does not seem to be working as well.
thanks
