[rules-users] WG: Drools Fusion 6.0.0.CR3

[Weiss, Wolfgang]

Hi all!

I tried out Drools 6.0.0.CR3 and I have some difficulties in detecting patterns with rules containing temporal parameters. I'm using following rule:

rule "detect turn shifts"
        agenda-group "evaluation"
        salience 100

    when
        $aae : AudioActivityEvent(value >= 50) from entry-point "LowLevelES"
        not(AudioActivityEvent(value < 50, userID == $aae.userID, this after[0, 300ms] $aae) from entry-point "LowLevelES")
    then
        logger.info("turn shift START, user ID: " + $aae.getUserID() + ", " + $aae.toString());
 // do something else ...
end

When inserting events following happens:
12:43:05,914 [main           ] DEBUG ReteooRuleBase                 - Starting Engine in PHREAK mode
12:43:06,225 [main           ] INFO  SemanticLifter                 - incoming event: AudioActivityEvent [userID=1, value=100.0]
12:43:06,295 [main           ] INFO  SemanticLifter                 - incoming event: AudioActivityEvent [userID=1, value=0.0]
12:43:06,344 [main           ] INFO  SemanticLifter                 - incoming event: AudioActivityEvent [userID=1, value=100.0]
12:43:11,096 [main           ] INFO  SemanticLifter                 - incoming event: AudioActivityEvent [userID=1, value=0.0]
12:43:11,100 [main           ] INFO  SemanticLifter                 - turn shift START, user ID: 1, AudioActivityEvent [userID=1, value=100.0]
...

The "turn shift start" should be detected 300ms after the third incoming event (12:43:06,344) which is not the case here. This rule worked for me when using Drools 5.5.0 and 6.0.0.Beta2 but not with 6.0.0.CR3 - I did not try any other version.
This is my code to insert events:
streamEntryPoint = ksession.getEntryPoint("LowLevelES");
...

streamEntryPoint.insert(lowLevelEvent);
ksession.getAgenda().getAgendaGroup("evaluation").setFocus();
ksession.fireAllRules();

"AudioActivityEvent" is declared as an event with the @role attribute. I also tried to use the following option: "RuleEngineOption.RETEOO", but with no difference.


Best regards,
Wolfgang
