RE: [rules-users] Plz reply : Descending order rule

Are you sure you only have three facts? Your original resultset showed "Order value=5" which is not in the dataset shown in your most recent email. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Barath Sent: 21 February 2008 10:34 To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] Plz reply : Descending order rule Hi, Let me say my understanding about this rule... 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 let this be A 2. Order value=2 let this be B 3. Order value=3 let this be C Case 1 : $a : Order($value : 1) not Order(2 > 1) So this rule is True. Case 2 : $a : Order($value : 1) not Order(3 > 1) So this rule is True. Case 3 : $a : Order($value : 2) not Order(2 > 3) So this rule is True. Case 4 : $a : Order($value : 2) not Order(2 > 1) So this rule is False. Case 5 : $a : Order($value : 3) not Order(3 > 1) So this rule is False. Case 6 : $a : Order($value : 3) not Order(3 > 2) So this rule is False. 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. Plz do help me..... Barath.
