If you don't want the same Object in RHS, you have to add one condition : rule "compare dates" when $f:FactObject($d1 : date) FactObject(this != $f, date == $d1) then end -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de Shyam, Pallav (MSCIBARRA) Envoyé : mardi 2 septembre 2008 18:06 À : Rules Users List Objet : RE: [rules-users] Checking facts between them rule "compare dates" when FactObject($d1 : date) FactObject(date == $d1) then end This assumes there is an object FactObject with attribute date. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Delaunay Gaetan Sent: Tuesday, September 02, 2008 9:17 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] Checking facts between them Hi all, I was wondering if it was possible to create a rule which checks if a fact is equal to another one. For example in my case i'd like to compare the date of fact with the date of fact +1. I hope you understand what i mean. What kind of rule will be suitable to do that?
