In Seam 1.0.x, all events are processed in the same thread and scopes that raised the event. So if you call raiseEvent("foo") , and you have an existing FooListener in the conversation scope, that will be the instance that processes the foo event. However, in Seam 1.1, there are raiseAsynchronousEvent() methods which let you process the event in a new thread and scopes.
