Re: [rules-users] Is there a better way to write this rule?

It only works if you do it like this: rule "Discount Egypt" salience 0 when $T : TripRequest ( destination == "Egypt" ) $dest: DiscountResult() then $dest= (DiscountResult) $T.getResult(); $dest.setDiscount(5); end Since getResult() returns an instance of the interface IResult, it needs to be cast to the proper type first. But this approach does not feel better than the previous notation. But thanks for the replies. -- View this message in context: http://drools.46999.n3.nabble.com/Is-there-a-better-way-to-write-this-rul...
