Im sure people have seen this before ive searched high and low for an answer but no luck, fairly new to using drools so any advice would be much appreciated. Here is a sample of my rules: rule "Gender Desirability" salience 400 no-loop true when $broker : Broker(brokerName=="bah") Proposer(gender == "F") then int desirability = $broker.getDesirability() + 10; $broker.setDesirability(desirability); update($broker); System.out.println("Gender Hit"); end rule "Age Desirability" salience 200 no-loop true when $broker : Broker(brokerName=="bah") $proposer : Proposer($dob : dateOfBirth) $rulesrequest : RulesEngineRequest($inception : inceptionDate) eval(age_desirability_flex.isInRange($proposer.getAge($dob,$inception))==true) then int desirability = $broker.getDesirability() + 20; $broker.setDesirability(desirability); update($broker); System.out.println("Age Hit"); end rule "Check Desirability" salience 190 when $broker : Broker($des : desirability,brokerName=="europa") eval($des < desirability_Index) then $broker.setInclude(false); retract($broker); end Ok basically all the 'when' bits work. But what seems to happen is that when the update happens and the rules are evaled again and it ping pongs between the two rules as they both update the Broker object. Resulting in the 'Check Desirability' never being hit and for debug spewing 'Gender Hit' 'Age Hit' in a infinite loop till te JVM runs out of memory and it crash and burns. Any help in this would be much appreciated. If you need any more information let me know as well.
