Thanks Edson. I don't why but when i am using the below rule in my drl it's failing to compile.
Not sure if i am doing something stupid or this is an issue with environment or the drl. I am attaching the drl file with the mail. The error that i get is : - testTestsRulesEngine( at suitability.RulesEngine.<init>( at suitability.TestsRulesEngine.<init>( at suitability.TestsRulesEngineTest.setUp( Caused by: suitability.TestsRulesEngineTest)suitability.RulesEngineException: Could not load/compile rules file: testAccumulate.drlRulesEngine.java:39)TestsRulesEngine.java:13)TestsRulesEngineTest.java:72)java.lang.NullPointerExceptionat org.drools.common.AbstractRuleBase.addPackages( at org.drools.reteoo.ReteooRuleBase.addPackage( at suitability.RulesEngine.<init>( ... 14 moreAbstractRuleBase.java:434)ReteooRuleBase.java:388)RulesEngine.java:36) Regards, Manav ________________________________ From: Edson Tirelli <tire...@post.com> To: Manav <manav7...@yahoo.com>; Rules Users List <rules-users@lists.jboss.org> Sent: Mon, August 16, 2010 7:46:54 PM Subject: Re: [rules-users] Accumulate in Drools You can't use the cast and the method call in a regular constraint. You can use it as part of an expression. So: $min_score : Number () from accumulate (Client (productTypeExperience.keySet contains $name, $score : productTypeExperience[$name], min ( ((ExperienceLevel)$score).value() ) ) We are working on the support of free form expressions on constraints for Drools 6 (not sure we can make it for 5.2).
