Re: [rules-users] Double

Hi Scott, My understanding is that the rule will only fire twice regardless because there are only two "SheetTotal" objects in working memory which is stopping the rule from going into infinite recursion. The no-loop attribute is also behaving correctly as it is not letting the engine add it back onto the Agenda. What is interesting however is that in this case the modify is behaving exactly as if I were to retract and then assert the DutyHourTotal object. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Scott Reed Sent: Wednesday, 30 May 2007 11:48 AM To: Rules Users List Subject: Re: [rules-users] Double Matthew Shaw's message received 5/29/2007 9:39 PM: > ok point taken.

The rule should just keep firing. If there were some condition on the DutyHourTotal that eventually was false it would stop but I am surprised you only see it fire twice and not forever. Perhaps there are side effects of setNrHours() that cause one of the other conditions to fail. > * > > end > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users This correspondence is for the named persons only.
