This overview page for the Channel API https://developers.google.com/appengine/docs/java/channel/overview
states in the "Caveats" section: "Only one client at a time can connect to a channel using a given Client ID, so an application cannot use a Client ID for fan-out. In other words, it's not possible to create a central Client ID for connections to multiple clients (For example, you can't create a Client ID for something like a "global-high-scores" channel and use it to broadcast to multiple game clients.)" I can confirm that you CAN have multiple clients listen on the same channel (via the same Channel ID) and that it works, a single message sent on the channel is received by all listening clients. Can anyone from google comment? - is the documentation out of date and the design and implementation do support this - am I "just lucky" and this could break any time....and I should be planning a redesign It seems a very useful design feature of channels when pushing out status updates to multiplayer games, group chats and many other use cases. I have tried having one page (GWT app) listen on more than one channel, and as stated in the Caveats, it seems to NOT work. As David Bowie would say: "If I say I can't do it, I can't do it, I don't make false claims" :-) Thanks. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
