    Description

      The behavior of binding of a boolean unary expression in executable model is different from the one in plain drl.
      Concretely, when executing a rule (*1) that uses binding of a boolean unary expression in executable model and in plain drl respectively, the binding works as also a constraint in executable model while it does only binding in plain drl. The behavior between both should be the same.

      (*1)

      package com.example.reproducer

dialect "java"

rule "rule19aT"
  when
    $bus: Bus( $flag : Boolean.valueOf("TRUE") )
  then
    System.out.println("***** Action of rule19aT: $flag = " + $flag);
end

rule "rule19aF"
  when
    $bus: Bus( $flag : Boolean.valueOf("FALSE") )
  then
    System.out.println("***** Action of rule19aF: $flag = " + $flag);
end

          • 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.
