This page demonstrates the ROLE XMPP Multiuser Chat Gadget (left) in connection with a teststub widget (right) simulating events coming from the RWTH Web 2.0 Knowledge Map. In order to simulate WKM interaction, first publish an event "loggedIn" and wait for the chat widget to connect and enter the room "all-wkm". Then, you can simulate selecting objects in the WKM by specifying and submitting an arbitrary object identifier. The chat widget will react by changing the user's presence and by entering a room "objectId-wkm". Finally, you can close the WKM session by publishing a loggedOut event.
