Well, here's the problem I'm having with objects that I have persisted to a
session.
I have a collection that is declared as persist="session". And I have the
following in my pageBeginRender method:
public void pageBeginRender(PageEvent event) {
if (getCollection() == null) {
setCollection(service.getCollection());
}
}
When I startup the application the first time, my collection is populated
from the service call nicely. However, if I open a *new* browser window (new
session), that service call never gets called. Which made me to believe that
persist="session" is shared among all sessions.
Any idea what I'm doing wrong here?

Persist=session will persist the property for the current user's
session. It won't be shared across sessions. Persist=session will do the
trick nicely for you.
