Hi, Can u explain me the rule flow for the below rule ?. This will help me to get some clear idea about rules. rule "Descending order" when $a : Order( $value : value ) not Order( value > $value) then System.out.println("value :"+$value); retract($a); end I am having the following , 1. Order value=1 2. Order value=2 3. Order value=3 4. Order value=4 5. Order value=5 Can u explain the flow(when part) for this 5 object ? Note my understanding(in when) : 1st line take one order object 2nd line check for any other object with grater 'value' But i dont know sequence in which the objects are taken. Plz do reply...... Thanks in advance, Barath. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

This indicates the rule should fire for three times but its not the case.

This indicates the rule should fire for three times but its not the case.

Hi, I apologize for my logic fault i made in previous post. The correct logic as follows, rule "Descending order" when $a : Order( $value : value ) not Order( value > $value) then System.out.println("value :"+$value); retract($a); end 1. Order value=1 2. Order value=2 3. Order value=3 Case 1 : $a : Order($value : 1) not Order(2 > 1) So rule is False. Case 2 : $a : Order($value : 1) not Order(3 > 1) So rule is False. Case 3 : $a : Order($value : 2) not Order(1 > 2) So rule is True. Case 4 : $a : Order($value : 2) not Order(3 > 2) So rule is False. Case 5 : $a : Order($value : 3) not Order(1 > 3) So rule is True. Case 6 : $a : Order($value : 3) not Order(2 > 3) So rule is True. This indicates the rule should fire for three times but its not the case. I know i going wrong some where but i couldn't figure out.
