Dependent rule not firing ------------------------- Key: DROOLS-1763 URL: https://issues.jboss.org/browse/DROOLS-1763 Project: Drools Issue Type: Bug Affects Versions: 7.0.0.Beta7, 7.3.0.Final Environment: Linux all versions. JDK 1.8.0 Update 144 Reporter: David Wade Assignee: Mario Fusco Attachments: 7.0.0.Beta6.txt, 7.3.0.Final.txt We have been using Drools since 2.x. Currently we use 7.0.0.Beta6 which works. We can't upgrade because since 7.0.0.Beta7 rules dependent on the consequence of another rule are not firing for some reason. This happens for us on 7.0.0.Beta7 through to 7.3.0.Final. Consider the following two rules. When run on 7.0.0.Beta6 both rules fire. From Beta7 through to 7.3.0.Final, only the SQ rule fire, despite the RC rule passing its conditions {code} rule "H2" salience -300 when segment:SegmentWithTax( containsTax("SQ") , notContainsTax("H2", "RC") ) then segment.addPercentageTaxEntry(taxCodeMap,"SQ","RC_13_PERCENT"); end rule "SQ" when segment:SegmentWithTax( !containsTax("SQ") ) then modify(segment) { addTaxEntry(taxCodeMap,"SQ_TRANSFER_TRANSIT_LESS_THAN_FOUR_HOURS") } end {code} Will attach Drools trace logging output * 2. One for [^7.0.0.Beta6.txt] , one for [^7.3.0.Final.txt] .
