Question

Below is the rule:

---

rule "RelStatusUpdateCalcCheck"
salience 55
no-loop true
when    
$evt : UpdateRateStatusReq(statusID == RateStatusEnum.READY.getValue() || == RateStatusEnum.HOLIDAY_ROLL_FORWARD.getValue() || == RateStatusEnum.ROLL_FORWARD.getValue()) from entry-point RequestStream
$rr : ReliableRate(rateId == $evt.getRateID())
$dr : DerivedRate(holidayFlag == false, grfLock == false, $lr : listInputRateId, $lr.contains($evt.getRateID()))    
then
cepService.relStatusUpdateCalcCheck($evt, $rr, $dr);

end**

---

The last condition states that if ‘holidayflag’ is false and other conditions are satisfied as well then only execute the the java method. But the method gets executed even when the holidayflag is true. Only when I restart my app server the method doesnt get executed when holidayflag is true. Why is this so?

Thanks for the reply. I got the root cause of this issue. Actually when I update the holidayFlag to 'true',the DerivedRate object is updated but the Drools session is never updated as the result of which when the rules gets executed it still refers to the old value. When I restart my app I load the Facts again that's why this issue gets resolved after restart.

Below is the code that i added in order to resolve this issue::
DerivedRate dr = (DerivedRate) qd.iterator().next().get("dr");
FactHandle fh = session.getFactHandle(dr);  --> new code
dr.setHolidayFlag(true);
session.update(fh, dr);      --> new code
