[jboss-jira] [JBoss JIRA] (DROOLS-3510) Decision table unable to generate rule for row with pattern without constraint

Decision table unable to generate rule for row with pattern without constraint ------------------------------------------------------------------------------ Key: DROOLS-3510 URL: https://issues.redhat.com/browse/DROOLS-3510 Project: Drools Issue Type: Bug Components: decision tables Affects Versions: 7.15.0.Final Reporter: Andre Piwoni Assignee: Mario Fusco Priority: Minor Attachments: MissingConstraint.xls, failingDecisionTable.xlsx When second condition refers to a field of a variable bound in first condition and there exists row/rule without condition constraint than decision table compiler fails to generate rules. See attachment. Expected rules to be generated: {code:java} rule "Test_1" when $factA:FactA(hasSomething == "true") $numberOfFactsB: Number(this > 0, this <= 1) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1)) then insert(X); end rule "Test_2" when $factA:FactA(hasSomething == "true") $numberOfFactsB: Number(this > 1, this <= 2) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1)) then insert(X); end rule "Test_3" when $factA:FactA() $numberOfFactsB: Number(this > 2, this <= 3) from accumulate(FactB(x == 1) from $factA.listOfFactsB,count(1)) then insert(Y); end {code} Also, there does not seem an alternative way to generate following rule using decision table: {code:java} rule "Test" when $factA:FactA($factsB: listOfFactsB) $numberOfFactsB: Number(this > 1) from accumulate(FactB(x == 1) from $factsB,count(1)) then insert(Y); end {code}
