Hi, I have a JSF2 app that is able to run on my local instance. However,
after I deployed to GAE, i encountered an object serialization runtime error
on pages containing a UIPrameter object (e.g. <f:param id="param1"
value="foo" />)
I've tried the same app on glassfish (local) and tomcat (local), and they
both run fine. I suspect maybe it is not as simple as object serialization
problem? Could it be concurrent thread related issue? I can use an extra
pair of eyes to spot what am I missing here. Thank you
