Yes I guess we've seen this. So we just have to figure out how to ask from the client side each time we want something updated e.g. a list of something. There I guess the poller is what we would use, and turn it off if we don't need it anymore. BTW is that by setting interval to 0(zero)?
Or any other better ways to ask for updates from a client? So fare we like myfaces/trinidad, so we will continue trying it out.
