Hi Steve,
Could you let some other value represent no car? (e.g., _.None?).
untested...
WITH CompanyCars.getCar(self.car_id) or NOT_FOUND COMPUTE car=RESULT, car_registration=registration OTHERWISE LET car=_.None car_registration="no car"
WHEN OBJECT CHANGED CALL HAS_CHANGED('car_id') and (self.car_id and CompanyCars.getItem(self.car_id).decommission(), ORIGINAL['car_id'] and (OLD['car'] and OLD['car'].commission())) SAVING car
Would that work?
Sure, that would work. The workaround I've chosen is to use CompanyCars.getItem(ORIGINAL['car_id']).commission() in place of OLD['car'].commission() Oh, and I jsut noticed, I had commission and decommission the wrong way around in the example :-) I'd still prefer SAVING to tolerate not-found attributes, though. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
