Hallihallo Marcus ;) It seems as if there is already a conversation running. Maybe there's a @Begin method in another bean that has been invoked before. And when Seam encouters the method you quoted then Seam complains that there is already a conversation. So there are two possibilities: - @Begin(join=true) to "take part" in the currently running conversation - @Begin(nested=true) to start a "sub-conversation" in the currently running conversation View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959497#...
