Hi all: I have a very basic doubt about Drools Fusion. I have two simple Java classes: EventA { String id; Date timestamp; Long duration; } EventB { String id; Date timestamp; Long duration; } I have a DRL file, where I declare this two classes as Events: declare EventA @role(event) @timestamp(timestamp) @duration(duration) end declare EventB @role(event) @timestamp(timestamp) @duration(duration) end I have a simple rule: rule "Basic Rule" dialect 'mvel' when $eventA: EventA($aId: id) from entry-point "time stream" then System.out.println("Event A " + $aId + " at " + $eventA.timestamp); end Finally, I have a test that starts a StatefulKnowledgeSession in STREAM mode, register an eventLister in the session in order to fire the rules when an event arrives: ksession.addEventListener(new DefaultAgendaEventListener() { @Override public void activationCreated(ActivationCreatedEvent event) { ((StatefulKnowledgeSession) event.getKnowledgeRuntime()).fireAllRules(); } }); And then the test insert in the "time stream" entry-point an instance of EventA with duration of 10 miliseconds, as follows: EventA eventA = new EventA(); eventA.setId("123"); eventA.setTimestamp(new Date()); eventA.setDuration(10L); ksession.getWorkingMemoryEntryPoint("time stream").insert(event); At the end of the test, I have an sleep of 2 seconds just in case. I don't understand why the "Basic Rule" never fires. But if I add another condition to the same rule, something like this: rule "Basic Rule" dialect 'mvel' when $eventA: EventA($aId: id) from entry-point "time stream" not EventB($aId == id, this after [0s,5s] $eventA) from entry-point "time stream" then System.out.println("Event A " + $aId + " at " + $eventA.timestamp); end The rules fires and I see this message in console: Event A 123 at Fri Dec 07 09:48:59 ART 2012 I don't understand why the first rule, that is more open, don't fire, and the second rule, that is more restrictive, fires without problems. Thank you very much! Greetings, Adrian. -- *Epidata Consulting | Deploying Ideas Ing. Adrián M.

Thank you, Esteban. You are right! If I insert two events A: rulesTest.addEventA("123"); rulesTest.addEventA("456"); The second call of fireAllRules() activates the rule for the first object: Event inserted com.epidataconsulting.drools.model.EventA Event A 123 at Fri Dec 07 11:54:21 ART 2012 Event inserted com.epidataconsulting.drools.model.EventA But not for the second. How I can do to correct this behavior? Thanks!

There should be a listener for afterActivationCreated, right?
