RE: [rules-users] Double
Hi Scott,
My understanding is that the rule will only fire twice regardless
because there are only two "SheetTotal" objects in working memory which
is stopping the rule from going into infinite recursion.
The no-loop attribute is also behaving correctly as it is not letting
the engine add it back onto the Agenda.
What is interesting however is that in this case the modify is behaving
exactly as if I were to retract and then assert the DutyHourTotal
object.

ok point taken. I have modified my rule so that it looks at an object
and I modify a property on that object instead as follows: But still
the same issue.
* *
*rule* "sum higher rate totals"
*salience* 970
*no-loop* *true*
*when*
timesheet : TimesheetTransferObject( )
total : SheetTotalTransferObject($ihrisType : ihrisType ->
($ihrisType.equals(ihrisType.getDutyHourTotal())), $payRate : payRate
->
($payRate.equals(timesheet.getOfficer().getSubstantiativeRate()) ==
*false*))
*eval*(total.getValue().doubleValue() > 0)
higherDutyTotal : DutyHourTotal( )
*then*
higherDutyTotal.setNrHours(DateUtils.addElapsedTimes(higherDutyTotal.g
etNrHours(),
total.getValue().doubleValue()));
*modify*(higherDutyTotal);
This modify call tells the rule engine to "look at
this DutyHourTotal
object again." The rule should just keep firing. If there were some
condition on the DutyHourTotal that eventually was false it would stop
but I am surprised you only see it fire twice and not forever. Perhaps
there are side effects of setNrHours() that cause one of the other
conditions to fail.
