[rules-users] Can get "not equal" (!=) to work but not "equal" (==) in LHS

Background: I’m a business user. Dev wrote the fact model and the initial rule set. I can’t configure the fact model, the agenda groups, or the java code that fires the rules. I can change the rules within the .drl file. My question has to do with those rules. The application is run as a web service. Each call has just one Autopolicy in its own stateless session. An Autopolicy has one or more Vehicles, and a Vehicle has one or more Package of insurance coverages. Autopolicy objects come in with a random float (RandomGenId) between 0 and 1. Based on that random float we assign the object to an experiment group (RuleFlowId). Based on the experiment group we then set the value of the packages. (See the code below.) Below, rules 0A and 0B work when I use ruleFlowId != “test” and ruleFlowId !=“control” respectively, but they don’t work with the much more straightforward approach of ruleFlowId == “control” and ruleFlowId == “test” (respectively). Does anybody have an idea why? Thank you! ------------------------------------------- rule "control group" agenda-group "Rules-Recommendation" salience 999998 no-loop true lock-on-active true dialect "mvel" when $autoPolicy : Autopolicy(randomGenId < 0.5) then modify($autoPolicy) {setRuleFlowId("control")}; // Default ruleFlowId is “1” logger.debug("control group set"); end rule "test group" agenda-group "Rules-Recommendation" salience 999997 no-loop true lock-on-active true dialect "mvel" when $autoPolicy : Autopolicy(randomGenId >= 0.5) then modify($autoPolicy) {setRuleFlowId("test")}; // Default ruleFlowId is “1” logger.debug("test group set"); end rule "Rule 0A: Set Packages for Control Group" agenda-group "Rules-Recommendation" no-loop true lock-on-active true dialect "mvel" when $autoPolicy : Autopolicy(ruleFlowId != "test") $vehicles : Vehicles() $packages : Packages() $vehicle : Vehicle() from $vehicles.Vehicle then // set $packages logger.debug("Rule 0A fired"); end rule "Rule 0B: Set Packages for Test Group" agenda-group "Rules-Recommendation" no-loop true lock-on-active true dialect "mvel" when $autoPolicy : Autopolicy(ruleFlowId != "control") $vehicles : Vehicles() $packages : Packages() $vehicle : Vehicle() from $vehicles.Vehicle then // set $packages logger.debug("Rule 0B fired"); end -- View this message in context: http://drools.46999.n3.nabble.com/Can-get-not-equal-to-work-but-not-equal...
