Major Description
I have a simple setup with just one single Session that backs a JSF xhtml file. Within that I fire an event, expeting that both the same session, and any other session will receive the event on submitting.
However, oddly enough, I can see that during the firing of the event, only the current session receives it, not any other sessions. I am making sure I have two different sessions by using two different browsers (Safari and Firefox in this case).
