current release of icefaces-seam-gen has TimerBeanImpl that does not work correctly for COMConcurrentViews. As well, it begins a new conversation for each time the interval-renderer updates the clock. Current scope is session. When changed to Page scope, get the following exception:-

Try to come up with some TimerImpl configuration for Seam (which doesn't have a request scope--is event scope similar?) and have it join whatever conversation is in progress.
