[rules-users] Getting Error while using Drools 5.3.0

Hi, My application works fine with Drools v 4.0.7. However, when I run my application using Drools 5.3.0, I am getting the following error: org.drools.rule.InvalidRulePackage: Evaluator '>' does not support type 'ValueType = 'String' : [Rule name='VIN required for newer vehicles'] at org.drools.rule.Package.checkValidity(Package.java:478) at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:481) at org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:458) at org.drools.reteoo.ReteooRuleBase.addPackage(ReteooRuleBase.java:465) Here is the condition I am using in my .dsl file: [condition][]request contains no VIN and the car was built after year {value}=info: CarRulesInfo(quoteRequest.VIN == null, quoteRequest.modelyear Any suggestions on how to fix this problem. Thanks in advance. -- View this message in context: http://drools.46999.n3.nabble.com/Getting-Error-while-using-Drools-5-3-0-... Sent from the Drools: User forum mailing list archive at Nabble.com.
