This is more a limitation or the nature of the http and other protocols than a defect in T5.
The polling scheme is only possibility that comes to my mind. If the user has not been heard of for a certain amount of time, he/she will be regarded as absent and removed from the room. Of course, what ever the user does to the client to move to another page stops the javascript that is sending the "still alive messages". You're going to have to write some custom js to do this, there isn't needed functionality in T5 that would do this AFAIK. - Ville BarryDev wrote: > > Hi all, > > I've completed the hi/lo and address tutorial and I'm not trying to write > a simple chatroom to learn some more about tapestry. > > My basic chatroom currently has a login page which forwards to a chatroom > which lists the usernames of all logged in users.
