    Description

      After upgrading RHDM from 7.10.1 to 7.12.1, when using non-executable model, if the capitalized property is updated in modify block of RHS, it behaves as class reactive and then unexpected rules gets executed.

      Here are example rule which caused the issue.

      rule "Target_Rule"
        when 
                $temp : TempObject(id == "1", $id : id, $MyList : MyList)
		$target : TargetObject(id == $id) 
        then
		delete($target);

		$MyList.remove($target);
		modify($temp){
			MyList = $MyList;
		}

		System.out.println("▼▼▼ Rule [Target_Rule] fires!!!");
end

      This is caused by RHDM-1639 which is fixed in 7.11.0.
      In addition, this does not happen when using executable-model.

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-7088 Property reactivity discrepancy between executable model and non executable model with a capitalized property

          • 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.
