Hmm,
Am i doing something wrong here then,
I have this code on the RHS:
--
(bind ?effRate (ognl-get ?pdLocation "getEffectivePerDiemRate(#date)" "date"
?pddate))
(if (eq ?effRate nil) then
;;(dts-log-error "No effective rate found for " (call
com.ngc.dts.util.DateUtils formatDateTime ?pddate))
return )
(bind ?expense (get-pde-expense ?entObj "mealsAndIncidentalsExpense"))
(set ?expense allowedCost (?effRate getCommercialMealRate))
--
But I am still getting this error:
--
Exception: JessException
Message: Can't call method on nil reference: getCommercialMealRate
In Class: jess.de
In Method: call() : null : -1
Jess reported an error in routine call
while executing (call ?effRate getCommercialMealRate)
while executing (set ?expense allowedCost (call ?effRate
getCommercialMealRate))
while executing defrule MAIN::assign-cmr.
--
The (if (eq ..)) test does not seem to resolve to true, and the (call) on the
nil ?effRate variable is still executed.
Am I doing something wrong here ?
