Developers: it would be *very nice* to have a clarifying statement as to whether the triplex relational expression is valid or not, so that a proper issue might be raised. Status in 5.3.0: accepted by the DRL parser and resulting in unknown semantics.

To: Rules Users List <rules-users(a)lists.jboss.org&gt; The Drools documentation states that the left side of any binding pattern of any conditional element must be a read-only property of the element (or nested property). As such you must rewrite your rule. Try this: rule "rule_Name" when per: Person(age >= 50 && < 100, income >= 10000 && < 50000, occupation == "Business", category == "Military", location == "Bangalore", custype == "Individual") pri: Price((price >= 20 && < 30) || price == 1) then System.out.println("Success"); end -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of shanmuga Sent: Sunday, February 05, 2012 3:33 AM To: rules-users(a)lists.jboss.org Subject: [rules-users] How to write rules in two fact's fields?
