[rules-users] Drools AgendaEventListener

Can anyone explain when the ActivationCreatedEvent, BeforeActivationFiredEvent,AfterActivationFiredEvent are actually triggered? I added a AgendaEventListener on a StatefulKnowledgeSession and never see the events being fired when I'm in the debugger. I'm basically trying to collect some session stats. Here's a snippet - KnowledgeBaseConfiguration kbaseConf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); kbaseConf.setOption(MBeansOption.ENABLED); commonKB = KnowledgeBaseFactory.newKnowledgeBase("kb-"+gameCode, kbaseConf); commonKB.addKnowledgePackages(kbuilder.getKnowledgePackages()); StatefulKnowledgeSession session = commonKB.newStatefulKnowledgeSession(); //session.addEventListener(bean.getAgendaStats()); session.addEventListener(new DefaultAgendaEventListener() { public void activationCancelled(ActivationCancelledEvent event) { System.out.println("activation cancelled"); } public void activationCreated(ActivationCreatedEvent event) { System.out.println("activation created"); } public void afterActivationFired(AfterActivationFiredEvent event) { System.out.println("after activation fired"); } public void beforeActivationFired(BeforeActivationFiredEvent event) { System.out.println("before activation fired"); } }); .. add facts.. Session.fireAllRules(); I never see the printlns or the breakpoints in the DefaultAgendaListener - are these supposed to be triggered when the rules are fired?
