Then the rule becomes more comprehensible: > > $l1 : LabResult( value < 1, eval( inLastMonth(date) ) > $l2 : LabResult( value < 1, eval( inLastMonth(date), > next == $l1 ) > $l3 : LabResult( value < 1, eval( inLastMonth(date), > next == $l2 ) > > It's also more easily extensible to longer sequences. > > GreG > > > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > -- Edson Tirelli JBoss Drools Core Development JBoss, a division of Red Hat @ www.jboss.com _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
