Seam 1.2.1.GA public class Conversation implements Serializable | ...... | public void beginNested() | { | if ( Manager.instance().isLongRunningConversation() ) | { | Manager.instance().beginNestedConversation( Seam.getComponentName(Conversation.class) ); | } | else | { | throw new IllegalStateException("beginNested() called with no long-running conversation"); | } | } | And I think you do not need nested conversations for this scenario. Do it in one conversation. Just throw away lower level selections when you make selection on some level. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4063941#...
