Yeah, I agree with Richard now that I know your trying to dynamically update it. The poll components will kick off the AJAX request and your partialTrigger (set to the poll component) will allow the text to change.
I would also suggest disabling the poll component when you don't expect any changes (ie. Maybe it doesn't start until the login is submitted and then it turns off after the login successfully completed). Does anyone know of "Streaming Requests" are handled in the next servlet spec? If so, it would be cool for JSF to Do something with them, allow renderkits like Trinidad to stream updates in a more generic fashion.
