[rules-users] WG: Second Rule does not recognize changes from first rule?

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
