Odd rules execution for expired events -------------------------------------- Key: DROOLS-311 URL: https://issues.jboss.org/browse/DROOLS-311 Project: Drools Issue Type: Bug Affects Versions: 5.5.0.Final, 6.0.0.CR5 Environment: Windows Vista 64, JRE6 (x86) Reporter: Karol Sobczak Assignee: Mario Fusco Priority: Critical Fix For: 7.0.0.Beta1 Attachments: expiredrules.zip I have declared two types: declare Motion @role( event ) @expires( 5s ) @timestamp( eventTime ) eventTime : long end declare Recording end and following rules: rule "StartRecording" when Motion() not Recording() then insert(new Recording()) end the problem is that when I put a lot of "Motions", sleep (so "Motions" become expired) and then do fireAllRules(), I got "StartRecording" executed multiple times (and not only once), event though "Recording" is inserted every time. Another issue would be when instead of "StartRecording" rule I would have "StopRecording" rule: rule "StopRecording" when $m : Motion() $r : Recording() then System.err.println("Recording: " + $r); retract($r); end then when there is a "Recording" fact inserted and multiple expired "Motions", the rule would be executed multiple times (when "Motions" expire) and $r would be null after the first "StopRecording" rule execution.
