I have the following rule, which is executing in the midst of a complex data set and a couple hundred other rules: rule "RS6492.1.2" when TransactionSummary ( $LTVRatioPrcnt : LTVRatioPrcnt ) PolicySet ( $maxLTVRatioPrcnt : maxLTVRatioPrcnt, maxLTVRatioPrcnt < $LTVRatioPrcnt ) then System.out.println("RS6492.1.2 fired. $maxLTVRatioPrcnt = " + $maxLTVRatioPrcnt + ", $LTVRatioPrcnt = " + $LTVRatioPrcnt); // actual actions removed ... end In the dataset, there are two PolicySets with maxLTVRatioPrcnt values of 95.0 and 80.0 respectively. The LTVRatioPrcnt in the TransactionSummary is 85.0. When my rules run, The above rule should fire only once, for the PolicySet with 80.0 as its maxLTVRatioPrcnt. However, it fires twice - once for each PolicySet - with the following outputs: RS6492.1.2 fired. $maxLTVRatioPrcnt = 95.0, $LTVRatioPrcnt = 85.0 RS6492.1.2 fired. $maxLTVRatioPrcnt = 80.0, $LTVRatioPrcnt = 85.0 How is this possible? Why is the comparison of maxLTVRatioPercnt < $LTVRatioPrcnt succeeding in both cases, causing the rule to fire on both PolicySets? I'm running Drools 5.0.0 with jars dated 15 Jan 09.
