Hi, I have Object of type Customer with int "field1, field2" and boolean "processed". (Example values field1 = 10, field2 = 180, not processed ) First, the condition in rule #1 was something like that: $customer : Customer (field1 ( ( > 0 && > field2) || < 0) && processed == false) ... but it doesnt work properly. So I changed it to rule "Rule #1" salience 46 when $customer: Customer ( ( ( field1 < 0 ) || ( (field1 > 0) && (field1 > field2) ) ) && processed == false) then // do it // set customer to processed end rule "Rule #2" salience 45 when $customer : Customer (field1 ( > 0 && < field2) && processed == false) then // do it // set customer to processed end The result is that both rules fired, both rules invokes "do it". Maybe somebody can put some helpfull ideas under my christmas tree. Thanks Thorsten Trägenap
