My guess is your backing bean containing your table data is in request
scope, and it no longer contains the data on the following request.
You can probably verify that this is the issue by temporarily adding
it in as session scope.
The real solution is probably to use x:saveState to perserve your
request-scoped bean until you no longer need it.
