Here's a working example of using AgendaEventListener...<br><br><a href="http://article.gmane.org/gmane.comp.java.drools.user/22375">http://article.gmane.org/gmane.comp.java.drools.user/22375</a><br><br>Your example has the line attaching the AgendaEventListener to the session commented out. This wouldn't help ;-)<br>

<div>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.</div>
