Order of parameters passed to the method called in accumulate function action() is unexpectedly changed in executable model. ---------------------------------------------------------------------------------------------------------------------------- Key: DROOLS-5941 URL: https://issues.redhat.com/browse/DROOLS-5941 Project: Drools Issue Type: Bug Components: executable model Reporter: Mario Fusco Assignee: Mario Fusco Priority: Major Labels: support Attachments: reproducer_model_compiler_5a.zip Executing a rule like (\*1) that uses {{action()}} accumulate function in which calls a method like (\*1-1) in executable model, the order of parameters passed to the method is unexpectedly changed and the parameters are not passed correctly. For example of the rule (\*1-1), {{$a.method(map, $bList, $cList, $dList)}} is actually called as {{$a.method(map, $cList, $aList, $bList)}}. (\*1) {noformat} package com.example.reproducer import java.util.List import java.util.Set import java.util.Map import java.util.HashMap dialect "java" rule "rule5a" when $aList : List() from collect( A() ) $bList : List() from collect( B() ) $cList : List() from collect( C() ) $dList : List() from collect( D() ) $eSet : Set() from accumulate( $a : A() from $aList, init( Map map = new HashMap(); ), action( $a.method(map, $bList, $cList, $dList); ), // ..... (*1-1) result( map.keySet() ) ) then System.out.println("***** Action of \"rule5a\" -- $aList = " + $aList + ", $bList = " + $bList + ", $cList = " + $cList + ", $dList = " + $dList + ", $eSet = " + $eSet); end {noformat}
