RE: [rules-users] Not looping the rule when more then 1 valid match is found

I wonder if you can use a Global (or a static variable) to do the same without really changing your rule. Something like this. Global Integer ruleFired; rule "try not to loop" when $a : A($code : code) $b : B(parentCode == $code) then if(ruleFired != 1) { addResult($a, $b); Drools.getWorkingMemory().setGlobal(“ruleFired”,1); } end From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Maxim Veksler Sent: Monday, January 26, 2009 5:52 PM To: Rules Users List Subject: [rules-users] Not looping the rule when more then 1 valid match is found Hello group, Assuming I have the rule: rule "try not to loop" when $a : A($code : code) $b : B(parentCode == $code) then addResult($a, $b); end and the classes: public class A { int code; } public class B { int parentCode; } I insert into the WM 4 objects : A(code = 1), A(code = 2); B(parentCode=1), B(parentCode = 2); I would like that after calling fireAllRules() only 1 match will be returned. I have no preference regarding which one, in the current situation 2 matches are returned. Anyone could suggest a method to enforce this ? Thank you, Maxim. MASTEK LTD.
