By the "solutions given" I didn't mean to tell mine was good, apparently it's not, I was talking about the other ones. -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de PAYET, Manuel Envoyé : jeudi 3 juin 2010 15:33 À : Rules Users List Objet : Re: [rules-users] Firing a rule if at least its two conditions are satified The solutions given are useable anyway, Thanks for this information GreG -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de Greg Barton Envoyé : jeudi 3 juin 2010 15:29 À : Rules Users List Objet : Re: [rules-users] Firing a rule if at least its two conditions are satified This will not work. Rules will not predictably react to changes in global variables. Use an object in working memory.

We have a rule with three conditions in this format: when Condition A Condition B Condition C then execute Action 1 Now we have a situation, in which the rule should fire if AT LEAST two of the three conditions are satisfied. Do you know how to implement this? Any ideas or hints? Many thanks and regards! skasab2s. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Firing-a-rule-if-at-l...
