a : A( modified == "false" ) ==> here "false" is a String and a.setModified( true ); ==> here true is a boolean from your use of modified, I presume that modified is of boolean type. If it is, you'd probably want to do something like rule "Rule3" dialect "mvel" when a : A( modified == false ) then a.setModified( true ); update( a ); end because, modified will never be equal to "false" in your file cause it"s a String ________________________________ De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de Fnu Mahalakshmi Envoyé : mardi 15 juin 2010 16:03 À : &#39;rules-users(a)lists.jboss.org&#39; Objet : [rules-users] Error with executing rules Hi guys, I have few .drl rules and 1 .brl rule (which I converted into a .drl rule as guided by the documentation online) All my rules get created and fired. But the converted .brl rule does not get executed only. I am unable to understand why. Anyway I can check how it is working?? I put in the most basic rule which should work: The coverted .drl file looks like this: rule "Rule3" dialect "mvel" when a : A( modified == "false" ) then a.setModified( true ); update( a ); end // A being my fact with attribute modified set to false in the beginning. The import statements are in a rule.package in the same folder. Please help me. I do not understand why this rule doesn't get executed. All others do!
