Good morning. I have a periodically updated view that throws the following exception:
Nov 03, 2015 11:21:49 AM com.sun.faces.context.AjaxExceptionHandlerImpl handlePartialResponseError

In this view I have a <p:poll/> that updates my refreshArea in cycle second intervals (cycle = 5 in my ManagedBean).
I searched a lot and found a link from DevMedia teaching how to work with Session and Filter, implemented based on example , but it did not help much.
