Re: [rules-users] [drools-planner] eval check doesn't provide the expected output
The statements inside eval() are java statements, not DRL statements.
In java "!=" means "not the same instance" (while in DRL
"!=" means "not
equal").
Try eval(!$roomCurriculumCode.equals($currCode))
HTH :)
With kind regards,

Hi,
I have the following rule and roomCurriculumCode and currCode are of
type String. If the check is equals "insertLogical" never happens, but
if the the codes are not equal as expressed below the "insertLogical" is
performed even if the strings are equal. What am I missing here
rule "RoomAndCurriculum"
when
$room : Room($roomCode : code, $roomCapacity : capacity,
$roomCurriculumCode : curriculumCode);
$curriculum : Curriculum($currCode : code);
eval($roomCurriculumCode != $currCode)
then
insertLogical(new IntConstraintOccurrence("RoomAndCurriculum",
ConstraintType.NEGATIVE_HARD, 1, $roomCapacity, $room, $currCode,
$roomCurriculumCode));
end
