Although not relevant to your problem: stick with the JavaBean convention: There should be private Integer maxMoney; Integer getMaxMoney(); etc. and then you write Person( maxMoney != null ) > **** > > ** ** > > $totalCost : Number() **** > > from accumulate( $trip : Trip( $cost : $trip.getCost() > ) from $person.getTrips(), **** > > sum( $cost ) **** > > ) > Again: Trip should have private Integer cost; Integer getCost() etc. and then you do Trip( $cost: cost ) ... To call an arbitrary method you should be able to do sum( $trip.getCost() ) All together: $person: Person( $maxMoney: maxMoney != null, $trips: trips != null ) Number( $spent: intValue > $maxMoney ) from accumulate( Trip( $cost: cost ) from $trips, sum( $cost ) ) -W > **** > > then **** > > // take action **** > > end **** > > ------------------- **** > > ** ** > > I have tried it with and without the $trip-variable (since I thought I > might have to use it to call its function). **** > > ** ** > > The error I get looks like this: **** > > ** ** > > Error INTERNAL_ERROR: Error: unknown:70:54 Unexpected token ')' **** > > java.lang.Exception: Error: unknown:70:54 Unexpected token ')' **** > > at > com.fluidops.coremgmt.ruleengine.PolicyTask.readRule(PolicyTask.java:489) > **** > > at > com.fluidops.coremgmt.ruleengine.PolicyTask.readRule(PolicyTask.java:419) > **** > > ** ** > > I would be very thankful if one of you could help me out here :) **** > > ** ** > > Best regards, **** > > Christian**** > > ** ** > > ** ** > > PS: I already had this question in the drools forum, it was, however not > forwarded to this mailing list, so please forgive me if it is a double post. > **** > > ** ** > > _______________________________________________ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > >
