It does not change as IntervalRequirement is immutable.

Yes using 5.3.0.Final from the Planner 5.3 download location.
After your suggestions, here my complete drl (you will probably recognize
some of your own code :)):
rule "intervalRequirementCovered"
when
$intervalReq : IntervalRequirement($interval : interval,
$position :
position, $staffingRequired : staffingRequired)
$matchingShiftAssignmentsCount : Number(intValue() <
$staffingRequired)
from accumulate(
$matchingShiftAssignments : ShiftAssignment(shiftStartTime <=
$interval
,
shiftEndTime > $interval, position == $position)
,
count($matchingShiftAssignments)
)
then
#actions
insertLogical(new
IntConstraintOccurrence("intervalRequirementCovered",
ConstraintType.NEGATIVE_HARD,
$matchingShiftAssignmentsCount.intValue() - $staffingRequired,
$intervalReq));
end
rule "hardConstraintsBroken"
salience -1 // Do the other rules first (optional, for performance)
when
$hardTotal : Number() from accumulate(
IntConstraintOccurrence(constraintType ==
ConstraintType.NEGATIVE_HARD, $weight : weight), sum($weight)
)
then
scoreCalculator.setHardConstraintsBroken($hardTotal.intValue());
end
Unfortunately still having the same issue, that is, updates on my planning
entity are not reflected in the engine. Drools Experts mentions the
following when updating facts:
"The update() method can only be used with objects that have shadow proxies
turned on".
Not sure how to check about those shadow proxies, but is it something worth
looking into?
Thanks,
Guy
