[rules-users] Salience not working

[sridhar123]

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
