I was pretty excited to see the example chat app, as I need something similar for a project I am working on. So I recreated it the way I needed it, but I am finding that the chat UI (like iMessage, etc) does not update without either posting or refreshing the screen. For example, if I am chatting with another person, and he responds, my screen will not update until I refresh. Is there a way to get it to automatically refresh? It would be great if the lists has a setting to refresh every X seconds.
