Thanks for your reply but this does not do what I want to do because I
don't want to put more priority to a rule over another one, I want this
rule to fire with the price object that has the highest length field,
considering there are more than one Price objects in the WM.
Any other ideas?? Am I trying something impossible or should I take
another approach?

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

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.
Cheers,
Max
