I am seeing some odd behavior where it seems that inference is not working when trying to use a flow process within a stateless knowledge session. I have tried to do the same thing in both stateful and stateless, and the behavior is different. It appears that if one rule inserts a fact in its right hand side that causes another rule in a different flow-group to become activated, the rule-flow (which should progress to the next flow group) will not allow that rule to fire if the session is stateless. It is possible I am confused about how a rule-flow evaluates or the order in which it evaluates with respect to inference, but it is working as I expected in a stateful session. An example: I have a simple rule flow with two flow-groups, group1 and group2. They are connected one after the other in a file with id TestFlow start->group1 -> group2 -> end I then have a simple rules file: declare Fact1 num: int end declare Fact2 num: int end rule "Rule1" ruleflow-group "group1" when Fact1() then System.out.print("FIRING 1"); insert(new Fact2()); end rule "Your Second Rule" ruleflow-group "group2" when Fact2() then System.out.print("FIRING 2"); end When used in a stateful session, both rules will fire and print their respective output. In a stateless, the second rule will never fire. To execute this test, I am using the same code against both a stateless and stateful session: FactType fact = kbase.getFactType("org.test", "Fact1"); Object one = fact.newInstance(); List cmds = new ArrayList(); cmds.add(CommandFactory.newInsert(one)); cmds.add(CommandFactory.newStartProcess("TestFlow")); cmds.add(CommandFactory.newFireAllRules()); // Only need this in stateful ksession.execute(CommandFactory.newBatchExecution(cmds)); Does anyone have any suggestions?
