That strange, i took a look at code involved. The upload is wrapped in
an UploadedFile at decode time. It is then sotred as submited value. I
thing the validation process move it to value (current value of
component, but not yet stored in backing bean until validation is fully
complete), this internal value is stored dureing the saveState() and
resotred during restoreState(). Is your JSF configured to store status
server-side or client side+?
