Hello, Maybe a typo mistake but both of your rules have the same agenda group (Phase1) Regards, Joel ________________________________ De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de Rongala, Kanthi Envoyé : lundi 2 novembre 2009 15:54 À : rules-users(a)lists.jboss.org Objet : [rules-users] Agenda Groups basic question Hi, I am new to Drools and trying my hands out at Drools 5. I cann't figure out how to use agenda- groups. I have a small drl file with two agenda groups and one rule per agenda-group. This doesn't seem to work. However if I happen to comment out the agenda-group attribute, the results are as expected. Please let me know what I am missing. package com.mscibarra.examples.drools.controllers; import com.mscibarra.examples.drools.domainentities.*; rule "Detect and Remove Duplicate Shelves" agenda-group "Phase1" lock-on-active dialect "mvel" when $universe : LibraryUniverse() $shelf : Shelf() from $universe.shelves $shelf2 : Shelf(this != $shelf) from $universe.shelves then System.out.println("Duplicate Shelves found::"+$shelf); // without the modify(), drools is not alerted about changes // $universe.shelves.remove($shelf); /* modify($universe) { shelves.remove($shelf); }; */ end rule "Singleton Shelf Detector" agenda-group "Phase1" lock-on-active dialect "mvel" when $universe : LibraryUniverse(shelves.size > 1) then System.out.println("Multiple Shelves found::"+$universe.shelves.size); End With Regards, Kanthi Swaroop Rongala ________________________________ NOTICE: If received in error, please destroy and notify sender.
