[rules-users] problem in firing dependent rules..

Hi All, I don't know whether I have encountered a strange problem or my understanding of drools is wrong. I have 3 rules out of which two are dependent. Between the dependent ones one rule makes the other rule eligible to fire but I don't know why the dependent rule is not firing. Below are the rules I have written. package com.valueMomentum; import com.valuemomentum.eligibilitymodel.oo.*; import java.util.ArrayList; global java.util.ArrayList list; rule "PolicyTierClassification" no-loop true when healthInsuredbindings : HealthInsured( weight >= 134 , weight < 157 , height == "4ft 10in" , gender == "Male" ) then healthInsuredbindings.setPolicyTier("Standard I"); System.out.println("PolicyTierClassification"); list.add("To determine tier based on insured gender, height and weight(weight>=134 , weight<157 , height==4ft 10in , gender==Male ) -> (PolicyTier = Standard I)"); ;end rule "AlcoholConsumptionClassRule" no-loop true when healthInsuredbindings : HealthInsured( alcoholConsumptionFrequencyPerWeek == "2-3" ) then healthInsuredbindings.setAlcoholConsumptionClass("B"); System.out.println("AlcoholConsumptionClassRule"); list.add("To derive the alcohol consumption class based on consumption frequencyalcoholConsumptionFrequencyPerWeek==2-3 -> (AlcoholConsumptionClass = B)"); end rule "UnderwritingFactorRule" no-loop true when healthInsuredbindings : HealthInsured( alcoholConsumptionClass =="B" ) then healthInsuredbindings.setUnderwritingFactor(1); System.out.println("UnderwritingFactorRule"); list.add("To derive UnderwritingFactor from alcoholConsumptionClass==B -> (UnderwritingFactor = 1)");end this my initial fact HealthInsured healthInsured = new HealthInsured(); healthInsured.setAge(25); healthInsured.setGender("Male"); healthInsured.setWeight(140); healthInsured.setHeight("4ft 10in"); healthInsured.setTobaccoUser("No"); healthInsured.setMotorcycleRider("No"); healthInsured.setRelationToInsured("Insured"); healthInsured.setUnderwritingFactor(0); healthInsured.setPolicyTier("Preferred"); healthInsured.setAlcoholConsumptionFrequencyPerWeek("2-3"); healthInsured.setAlcoholConsumptionClass("A"); Based on the above fact PolicyTierClassification, AlcoholConsumptionClassRule are eligible to fire. AlcoholConsumptionClassRule is setting a property alcoholConsumptionClass to B based on which UnderwritingFactorRule rule becomes eligible fire but in this case the dependent rule is not firing. I think we can use update in AlcoholConsumptionClassRule but I think if we have to manage those dependencies it will be more error prone and the results are might be more inconsistent. I have tested it Using RETEOO in drools 3.x and 4.x which yields me the same results. But when I used LEAPS algorithm then i even got the dependent rule i.e UnderwritingFactorRule rule also fired. Thanks in Advance, sudhir.
