Re: RE : [rules-users] How to handle priority in a rule

you can affect a numero to salience in fact salience is used to give a priority to rule and the rule who has the numero of salience more priority rule "Price Product rule using price length" salience 500 ( for exemple ) when $s : Product (length > 0) $price : Price($length: length) then $s.setAmount($s.getAmount() + $price.getAmount()); $s.setLength($s.getLength() - $length.intValue()); modify($s); end */Maxime <mcatelin(a)perinfo.com&gt;/* a écrit : Hello, I'm trying to find how to manage priority within a rule. Let me explain the problem. I'll try to be as clear as possible but bear with me since I am new to rules. We have two objects, the Product is the object I'm trying to price and the object Price is the one that knows all the prices. Both products and prices have fields amount and length. Product amount is initialized to 0 and prices are going to determine the product amount depending on its length. Let's see an example : Product : P -> length = 5, amount = 0 Price : P1 -> length = 1, amount = 50 Price : P2 -> length = 3, amount = 100 With this configuration, after asserting the 3 objects to the WM, the amount field of Product P should have a value of 200 ( 1*100 + 2*50) because the price with the greatest length should be favored over the other ones. Here is the rule I made : rule "Price Product rule using price length" when $s : Product (length > 0) $price : Price($length: length) then $s.setAmount($s.getAmount() + $price.getAmount()); $s.setLength($s.getLength() - $length.intValue()); modify($s); end This is obviously wrong because it always takes the first asserted price object. I don't know how to make a rule which would take the amount of the price object with the greatest length in priority. Any help would be very much appreciated.
