[rules-users] Double

Why is it seeing it as a new object? I am asserting it into the working
memory before hand.

highDutyTotal is a new fact inside of your consequence, so when you call
modify, it's actually working as an assert - you are not doing a modify
there at all.

	Hi there,
	 
	seeing some very strange behaviour from the following rule
	 
	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)

	highDutyTotal : Double( )

	then

	highDutyTotal = new
Double(DateUtils.addElapsedTimes(highDutyTotal.doubleValue(),
total.getValue().doubleValue()));

	modify(highDutyTotal)

	end

	In my test the rule fires twice when I don't call modify. Which
is the expected behaviour because I have two unqiue
SheetTotalTransferObject objects.

	However when I call modify on the Double object the rule only
runs once. This is incorrect behaviour.

	 

	Can anyone offer any clues as to what may be happening here. Is
it to do with my use of the Double type?
