[jboss-jira] [JBoss JIRA] (DROOLS-422) Timer based rules don't fire and facts can't expire after session restore

Timer based rules don't fire and facts can't expire after session restore ------------------------------------------------------------------------- Key: DROOLS-422 URL: https://issues.jboss.org/browse/DROOLS-422 Project: Drools Issue Type: Bug Affects Versions: 5.5.0.Final Environment: Linux Mint 15 JBoss AS 5.1 Reporter: Nedo Nedic Assignee: Mark Proctor Attachments: drools-mongodb-persistence.zip I have implemented a custom persistence engine for Drools sessions in MongoDB. When session is built for first time, everything works like a charm. I am having some problems when Drools sessions are restored from MongoDB collection. Firstly, interval based rules (for example timer(int: 10s 10s)) don't fire. Some facts that should expire, they just don't expire and remain forever in WM. I attached the source code. When session is built for first time, I use code like this: KnowledgeBase kbase = createKBase(getKnowledgeBuilder(rulePackagePath), config); if (hasKnowledgeAgent) { createKnowledgeAgent(kbase, correlatorId); wm = (ReteooStatefulSession) ((KnowledgeBaseImpl) kagent .getKnowledgeBase()).ruleBase.newStatefulSession( (SessionConfiguration) ksconf, env); ksession = new StatefulKnowledgeSessionImpl(wm, kagent .getKnowledgeBase()); stateOutputMarshaller = StateMarshallerFactory.newOutputMarshaller(this, ksession, ksconf); stateOutputMarshaller.init(); ((InternalKnowledgeRuntime) ksession).setEndOperationListener(this); } Then, after every action I update the session in MongoDB collection. public void endOperation(InternalKnowledgeRuntime ikr) { stateOutputMarshaller.marshall(); } For session restoring, after AS restart I use this code: KnowledgeBase kbase = createKBase( getKnowledgeBuilder(rulePackagePath), getKBaseConfig() ); stateInputMarshaller = StateMarshallerFactory.newInputMarshaller( this, kbase, getSessionConf() ); ksession = stateInputMarshaller.unmarshall(correlatorId); stateOutputMarshaller = StateMarshallerFactory.newOutputMarshaller( this, ksession, getSessionConf() ); ((InternalKnowledgeRuntime)ksession).setEndOperationListener(this); protected static KnowledgeBaseConfiguration getKBaseConfig() { KnowledgeBaseConfiguration config = KnowledgeBaseFactory .newKnowledgeBaseConfiguration(); config.setOption(EventProcessingOption.STREAM); return config; } protected static KnowledgeSessionConfiguration getSessionConf() { KnowledgeSessionConfiguration ksconf = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(); ksconf.setOption(ClockTypeOption.get("realtime")); return ksconf; } Any help is appreciated. Thanks
