We just implemented a chat pod that we want to make available to all our rooms.
Initially we got it into a room by logging in as owner. Then we verified that the new CollectionNode was present and made that room into our template.
Creating rooms based on that template from the Ruby api did not work - the created rooms had no CollectionNodes. So we created them from the Room Console available in the AIR app.
Inspecting them through the console showed that they had the new node (myChat_SimpleChatModel).
Yet when we log into a room it seems to revert to our older set of CollectionNodes.
