Fwd: [rules-users] syntax question

Hi Bruce, From my experience (with 3.1-M1) you can reference bound Facts/Columns in subsequent patterns; like:- $m : Manufacturer ( name == "Honda" ) $c : Car ( manufacturer == $m ) $c : Customer ( cars contains $c, age > 18 ) $cars.contains("Honda") requires an eval statement as your requirement is equivalent to "Customer ( cars.contains("Honda") )" which does not use a zero-parameter field accessor and is not compliant with the Java Beans specification). With kind regards, Mike ------------------------------ *From:* rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] *On Behalf Of *Bruce leroy *Sent:* 23 March 2007 18:20 *To:* rules-users(a)lists.jboss.org *Subject:* [rules-users] syntax question Hi, I have a question regarding rules syntax particularly with left hand side. Suppose I have the following condition .. when Customer ( $cars : cars, age > 18 ) ... How can I use the bind variable "$cars" in subsequent statements without using eval(), like so ... when Customer ( $cars : cars, age > 18 ) eval( $cars.contains( "Honda" ) ) .... Basically I would like to know what the alternatives for doing something like so this without having to use eval function. I know this might not be the best example for this question, but please I'm just learning this system right now. Thanks in advance, Bruce. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
