4:42 p.m.
Here is my drl file: It seems LHS of all rules executed first irrespective
of salience or focus. What am i doing wrong? Appreciate your help.
rule "Eval Window"
salience 10
agenda-group "Eval Window"
// activation-group "Eval Window"
auto-focus true
when
$data : AirTravelPolicyData($reqDep : fareRequest.requestedDeparture,
$reqRet : fareRequest.requestedReturn,
$itr : itinerary,
$evalWindow : policySettings.evaluationWindow,
$depart : departureFlight.departure,
$retrn : returnFlight.departure
)
eval ((DateUtil.subtractHours((Date)$reqDep,
((Integer)$evalWindow).intValue()))
.before((Date)$depart))
then
// modify block sets $itr.discardable to true
modify($itr) {
setAsDiscardable()
}
// update ($data);
drools.setFocus("Eval carrier");
end
rule "Eval carrier"
salience 5
agenda-group "Eval carrier"
// activation-group "Eval carrier"
when
$data : AirTravelPolicyData($prefCarrier : policySettings.preferredCarrier,
$carrier : departureFlight.carrier,
$discard : itinerary.discarded
)
// Eval Window rule changed discarded flag to true so this condition
should fail but it dose not ???
eval(((Boolean)$itr).booleanValue() == false)
then
// But.. when i print out the discard flag here it show as true.. In that
case how eval condiation is passed?
System.out.println("*********Current Itr in Eval carrier: " +
$discard );
end

This is wrong:
$data : MyFact( $anotherObj )
Is the parser accepting it without any error???? If so, it is a bug.
I can't even imagine what is the parsing result for such expression.
This is also wrong:
eval ($anotherObj.isDiscard() == true)
There is no previous binding for "$anotherObj". Only possible scenario
is
you defined it as a global.
So, whatever you are doing and seeing, I have no idea how you can
execute
rules.
Can you show us the whole DRL file you are using? Can you show the
snippet of code you are using to execute it?
