Re: [rules-users] Drools : 2 identical calls to the same knowledgeBase don't give the same result… why?

Hello, I've faced some weird result using Drools 5.5.0.Final, and I would like to know if I am doing something wrong ? I am using drools to process some user rules (the Excel way). If I call the rules with the exact same data at different time in the process, I don't get the same result. (I am using a StateLessSession) After digging a bit more, I managed to extract a very simple maven-based unit-test to reproduce the problem. (the archive can be downloaded here : http://www.filedropper.com/using-drools <http://www.filedropper.com/using-drools> ) In fact, I call many times to execute the same rule, and after the 23rd times I don't get the same expected result : @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({ "classpath:status-rules-config.xml" }) public class StatusRuleTest { @Autowired StatusRule ruleRunner; @Test public void do_not_work_at_25th_call() throws Exception { for(int i = 0 ; i < 35 ; i++){ MyFact fact = new MyFact(); assertThat(fact.getStatus()).isEqualTo("NONE"); ruleRunner.defineStatus(fact); assertThat(fact.getStatus()).isEqualTo("DONE"); } } } with rule definition as : public class StatusRuleImpl implements StatusRule { @Setter private StatelessKnowledgeSession ksessionStatus; @Override public void defineStatus(MyFact myFact) { ksessionStatus.addEventListener(new DebugAgendaEventListener() ); ksessionStatus.addEventListener(new DebugWorkingMemoryEventListener()); ksessionStatus.execute(myFact); } } It uses a statelessSession, with sequential mode and ACTIVATION-GROUP column. I also posted more details and more logs here : http://stackoverflow.com/questions/21585666/drools-2-identical-calls-to-t... <http://stackoverflow.com/questions/21585666/drools-2-identical-calls-to-t... >From what I checked, it might be coming from the negative BigDecimal (If I change it to 10 in both of the code and the Excel, it seems to work) If someone has an Idea, I will be pleased to read it !
