Hi, 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. It seems that inserting new recording does not cancel expired activations. Is that correct? How to handle such situation correctly? -- View this message in context: http://drools.46999.n3.nabble.com/Odd-rules-execution-for-expired-events-...

Code is: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newClassPathResource( "rules.drl" ), ResourceType.DRL ); KnowledgeBuilderErrors errors = kbuilder.getErrors(); if ( errors.size() > 0 ) { for ( KnowledgeBuilderError error : errors ) { System.err.println( error ); } throw new IllegalArgumentException( "Could not parse knowledge." ); } KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); config.setOption( EventProcessingOption.STREAM ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( config ); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); KnowledgeRuntimeLoggerFactory.newFileLogger( ksession, "test" ); for (i = 0; i <= 1000; i++) { ksession.insert(new Motion(System.currentTimeMillis())); } Thread.sleep(10 * 1000); //wait for motion events expire (simulate hi rules engine load) ksession.fireAllRules(); //I have println in rules so I can see that they are executed multiple times -- View this message in context: http://drools.46999.n3.nabble.com/Odd-rules-execution-for-expired-events-...
