Guys - think this is bad news for me... I need to use 'contains' keyword as List comparison against several variables from the primary Fact and possibly against several Lists. Without the ability to bind variable names to specific ArrayList objects I don't know how I can do this type of comparison in my rules - I hope there is a work-around to my problem, otherwise this may be a deal killer for my project... What I dont understand is that Edson's example seemed to get me so close - he gave this example some time in the past, which seems to illustrate that variable binding to List object is possible. How is his example different from what I'm trying to do in my code? Again, this is what I need: Several Lookup list objects each with many String elements asserted into memory. One main Fact (GATEIN) asserted into memory as well, the GATEIN fact has CustNumber, shipper_code, forwarder_code, cosignee_code, etc). Rule needs to check for existence of one of these codes in ONE or MORE lookup lists. Something like this: if (CustomerNumber = "293" and (ShippersList contains shipper_code or ShipperList contains forwarder_code, or ShipperList contains cosignee_code) ). Is this possible given the syntax constraints? BTW, I'm using 3.1.0M1 James Edson's prvious example: ------------------------------------------------ > rule "retrieving the list" > when > Customer( $custCode : customer_code ) > then > List codes = lookupDAO.getLookup( $custCode ); > assert( codes ); > end > > rule "doing something" > when > Customer( $custCode : customer_code ) > $list : List() > SHIPMENT_MOVE(customer_code == $custCode, $sc : ship_code, > $dc : deliver_code, $pc : port_code, > ( $list.containts($sc) || > $list.containts($dc) || $list.containts($pc) ) ) > then > // do something > end ------------------------------------------------ -- View this message in context: http://www.nabble.com/Struggling-with-Rule-syntax---please-help...-tf3408727.html#a9619455 Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list [email protected] https://lists.jboss.org/mailman/listinfo/rules-users
