Re: [rules-users] rule evaluation during insert

Hi, I'm using drools expert. When I insert the User object again in the session, after modifying the member variable 'trades' (details mentioned below) the rule doesn't get evaluated. It evaluate the rules only during the 1st insert. Is there a way to trigger the rule evaluation after every insert of the same object (when state is modified)? I've following declaration and rule. ------------ declare User @timestamp(datetime) name : String trades: Integer end rule "Trades" when $u:User(trades >= 3) then System.out.println("Trades > 3 for "+ $u.getName()); end ---------- Following is the piece of code: StatefulKnowledgeSession session = s.kbase.newStatefulKnowledgeSession(); String[] names = new String[]{"bob", "sam", "john"}; FactType userType = s.kbase.getFactType("com.sample", "User" ); Map<String, Object> name2user = new HashMap<String, Object>(); for( String name: names ){ Object u = userType.newInstance(); userType.set(u, "name", name); name2user.put(name, u); } userType.set(name2user.get("bob"), "trades", 1); session.insert(name2user.get("bob")); session.fireAllRules(); userType.set(name2user.get("bob"), "trades", 3); session.insert(name2user.get("bob")); // this insert doesn't evaluate the rule and hence the // condition $u:User(trades >= 3) is not checked session.fireAllRules(); Thanks & Regards, Neelesh _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
