Recursive Loop with no-loop true

[natraj.gudla]

Hi, We are trying to test a simple DRL which has 2 rules. The first rule modifies the object attribute which the second rules checks for. But it is observed that the execution is going into an infinite loop even after setting the "no-loop true" for both the rules.
We are using the Drools 3.0.6. Check the codes below....Any help?? Seems like more than one modify call on the object is forcing it into a loop. A single modification does not seem to have this problem.

DRL File:
#created on: Jun 21, 2007
package com.sample
import com.sample.LoanApplication;
#list any import classes here.
#declare any global variables here
rule "Your First Rule"
no-loop true;
when
lA: LoanApplication(ageBracket == 10)
then
System.out.println(" Cond Success ");
lA.setProductType("Product10");
modify(lA);

end

rule "Your Second Rule"
no-loop true;
#include attributes such as "salience" here...
when
lA: LoanApplication( productType == "Product10" )
then
System.out.println(" Base is 10 ");
lA.setProductType("ProductType20");
modify(lA);
end


JAVA CLASS FILE:

package com.sample;

public class LoanApplication {

public Person person;
public String risk;
public int priorClaims;
public String productType;
public int base;
public String recordReason;
public int discount;
public int ageBracket;

public int callageBracket(){
//System.out.println(" Custom method called ");
return ageBracket;
}
public int getAgeBracket() {
//return person.age;
return ageBracket;
}

public void setAgeBracket(int ageBracket) {
this.ageBracket = ageBracket;
}

public static void main(String[] args) {
// TODO Auto-generated method stub
}

public int getBase() {
return base;
}

public void setBase(int base) {
this.base = base;
}

public int getDiscount() {
return discount;
}

public void setDiscount(int discount) {
this.discount = discount;
}

public Person getPerson() {
return person;
}

public void setPerson(Person person) {
this.person = person;
}

public int getPriorClaims() {
return priorClaims;
}

public void setPriorClaims(int priorClaims) {
this.priorClaims = priorClaims;
}

public String getProductType() {
return productType;
}

public void setProductType(String productType) {
this.productType = productType;
}

public String getRecordReason() {
return recordReason;
}

public void setRecordReason(String recordReason) {
this.recordReason = recordReason;
}

public String getRisk() {
return risk;
}

public void setRisk(String risk) {
this.risk = risk;
}

}
