    Description

      Executing a rule like (*1) in executable rule model, the rule is evaluated repeatedly. In this rule, re-evaluation occurs in executable model though @watch(!*) annotation is specified to the pattern like (*1-1). @watch annotation containing !* as below does not work as expected, as well as @watch(!*).

      • @watch(!*, point2)
      • @watch(!*, point1)
      • @watch(point1, !*)

      On the other hand, @watch not containing !*, for example, @watch(!point1, point2) or @watch(!point1, point3), works as expected.

      (*1)

      package com.example.reproducer

dialect "mvel"

rule "rule9b3"
    when
        $fact : Fact( $point1 : point1, $point2 : point2 ) @watch(!*)  // ..... (*1-1)
    then
        System.out.println("***** Action of \"rule9b3\" -- $fact = " + $fact + ", $point1 = " + $point1 + ", $point2 = " + $point2);
        $point1 = $point1.add($point2);
        modify($fact) {
            point1 = $point1,
            point3 = $point1
        }
end

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-5961 @watch annotation containing "!*" does not work as expected in executable model.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
