[rules-users] Problems with int and Integer inside Return Value and Predicate Expression

The Solicitud object has sumaMontoLCG and sumaMontoGarantia atts as int (primitives). Im using 3.0.6 and java 1.5 I have this simple rule: rule "montos maximos y minimos" salience 888 when a: Actor(tipo :tipoActor == Actor.JefeOficina, max: limiteMaximo, min: limiteMinimo) s: Solicitud( sumaLCG: sumaMontoLCG < max, sumaGTIA: sumaMontoGarantia -> ( (sumaLCG.intValue() - sumaGTIA.intValue()) < min.intValue()) ) then System.out.println("Suma LCG:"+sumaLCG); System.out.println("Actor lim max:"+max); System.out.println("Actor tipo:"+tipo); end Fire the rule shows me this error: org.drools.RuntimeDroolsException: java.lang.ArrayIndexOutOfBoundsException: 1 at org.drools.rule.PredicateConstraint.isAllowed(Unknown Source) at org.drools.common.BetaNodeBinder.isAllowed(Unknown Source) at org.drools.reteoo.TupleSource.attemptJoin(Unknown Source) at org.drools.reteoo.JoinNode.assertTuple(Unknown Source) at org.drools.reteoo.LeftInputAdapterNode.createAndAssertTuple (Unknown Source) at org.drools.reteoo.LeftInputAdapterNode.assertObject(Unknown Source) at org.drools.reteoo.ObjectSource.propagateAssertObject(Unknown Source) at org.drools.reteoo.AlphaNode.assertObject(Unknown Source) at org.drools.reteoo.ObjectSource.propagateAssertObject(Unknown Source) at org.drools.reteoo.ObjectTypeNode.assertObject(Unknown Source) at org.drools.reteoo.Rete.assertObject(Unknown Source) at org.drools.reteoo.ReteooRuleBase.assertObject(Unknown Source) at org.drools.reteoo.ReteooWorkingMemory.doAssertObject(Unknown Source) at org.drools.common.AbstractWorkingMemory.assertObject(Unknown Source) at org.drools.common.AbstractWorkingMemory.assertObject(Unknown Source) at cl.bluesoft.jbrules.loader.solcred.SolcredRulesPoC.fireRulesSOLCRED (SolcredRulesPoC.java:85) at cl.bluesoft.jbrules.loader.solcred.SolcredRulesPoC.main (SolcredRulesPoC.java:40) Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at org.drools.reteoo.FactHandleList.get(Unknown Source) at org.drools.reteoo.TupleKey.get(Unknown Source) at org.drools.reteoo.ReteTuple.get(Unknown Source) at org.drools.reteoo.ReteTuple.get(Unknown Source) at cl.bluesoft.jbrules.rules.solcred.Rule_montos_maximos_y_minimos_0Predica te0Invoker.evaluate (Rule_montos_maximos_y_minimos_0Predicate0Invoker.java:14) ... 17 more When I change the column to: s: Solicitud( sumaLCG: sumaMontoLCG < max, sumaGTIA: sumaMontoGarantia -> ( (sumaLCG - sumaGTIA) < min) ) its shows this error: org.drools.rule.InvalidRulePackage: Rule Compilation error The operator - is undefined for the argument type(s) java.lang.Integer, java.lang.Integer at org.drools.rule.Package.checkValidity(Unknown Source) at org.drools.common.AbstractRuleBase.addPackage(Unknown Source) at cl.bluesoft.jbrules.loader.solcred.SolcredRulesPoC.readRule (SolcredRulesPoC.java:60) at cl.bluesoft.jbrules.loader.solcred.SolcredRulesPoC.main (SolcredRulesPoC.java:36) This happens in a predicate or in a value expression, so I cant use this formula... What is wrong? Thx. Felipe Piccolini M. felipe.piccolini(a)bluesoft.cl
