Hello,
i am a newbie at JBoss Rules and have a problem with a ruleset. Here are my
rules:
rule "1.CallsPerDay" --> Modifies the "CallsPerDayOfWeek" objects.
salience 35
when
$dayObj: CallsPerDay( $day: dayOfWeekS != null, $calls:calls > 0
)
$dayInWeek: CallsPerDayOfWeek( day == $day )
then
$dayInWeek.addCalls($calls); --> Changes call variable.
System.out.println("Drools: "+$dayObj.getInfo()+" /
"+$dayInWeek.getCalls());
End
//Output: Drools: On Mo 02/19/2007 12:00:00 AM 97 calls came in. / 104
rule "2.ProcessAgents" -> Should only process on changed "CallsPerDayOfWeek"
objects (calls must be 104 but seem to be still 0)
salience 35
when
$dayInWeek:CallsPerDayOfWeek ($callsTMP: calls==0, sum == 0)
then
System.out.println("Sum = "+$dayInWeek.getSum()+" for
"+$dayInWeek.getDay()+" CallTMP: "+$callsTMP+" /CallReally:
"+$dayInWeek.getCalls());
end
//Output= Sum = 2 for Mo CallTMP: 0 /CallReally: 104
Why is the "calls" variable still 0 at the beginning of rule
"2.ProcessAgents", although it was modified by the rule "1.CallsPerDay"?
with kind regards
Martin
