Thank you Mark and Edson! That's it :-) I was bemused because of the name fireALLrules. thank you for your help! From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Edson Tirelli Sent: Tuesday, February 05, 2008 12:18 PM To: Rules Users List Subject: Re: [rules-users] Dynamic Rules will not be executed Since you are (re)using a stateful session, rules that fired before will not fire again just because you changed the rulebase. This is expected behavior. []s Edson 2008/2/5, Michael Katai <mk.others(a)gmx.at&gt;: Hello! I've googeled and searched the mailing list archive, but i couldn't solve my current problem: Every time i create a new rule (while runtime) i use: PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(source); if(builder.hasErrors()) ... Package pkg = builder.getPackage(); ruleBase.addPackage(pkg); session.fireAllRules(); Every time, fireAllRules is executed, only the last, newest rule will fired. Where is my mistake? ruleBase (and factspace) is created as session = ruleBase.newStatefulSession(); factspace = new FactSpace(session); thanks in advance, michael _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli JBoss Drools Core Development Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com
