Well, I already suggested to you that the Drools Engine must be *informed*about changes to facts if these changes should trigger any rules. In rule "Preset" you have $d.preset($i); but this must be written as modify( $d ){ preset( $i ); } -W 2010/4/16 Ade Timi <adeyinka.timi(a)nathean.com&gt;

Thanks guys.

Just don't use ; inside the modify block: modify( $d ) { preset( $i ) } Edson 2010/4/16 Wolfgang Laun <wolfgang.laun(a)gmail.com&gt; Well, I already suggested to you that the Drools Engine must be informed about changes to facts if these changes should trigger any rules.

But now I'm having my initial number comparison problem. I am using a rule flow that runs preset 1st and then customer details. It is acting weird in that it never runs customer details with the cpointer == 2 condition. It only runs it when I change the condition to cpointer <= 2 and then its print statement returns the value 2! What am I doing wrong? rule "Joint App" ruleflow-group "customer_details" when $d : IndividualDecision(cpointer == 2) then $d.setWfResult("Yes"); $d.setJointApp(true); System.out.println("Customer pointer " + $d.getCpointer()); System.out.println("Customer Details(Joint App)? " + $d.getWfResult()); end rule "Preset" ruleflow-group "preset" when $d : IndividualDecision() $i : Individual() then $d.preset($i); System.out.println("Custpointer: " + $d.getCpointer()); System.out.println("Preset.........."); End public class IndividualDecision { . . . private int cpointer; /** * @param customerPointer the customerPointer to set */ public void setCpointer(int cpointer) { this.cpointer = cpointer; } /** * @return the customerPointer */ public int getCpointer() { return cpointer; } /** * @param ind. * Preset for Calculator */ public void preset(Individual ind) { this.setDecision("Error"); this.setCpointer(2); this.setDepositPercentage((ind.getDepositLomabard() / ind.getAmountFinanced()) * 100); this.setAssetAgeInYears(ind.getAssetAgeYears()/12); } } _____ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Edson Tirelli Sent: 15 April 2010 14:59 To: Rules Users List Subject: [rules-users] Fwd: Double Handling Sorry, I meant to send this to the list.

Meanwhile, you can rename your method or use a trunk snapshot.
