Hi guys, Thanks for the response. When I store data as a collection the rules don't seem to get fired. I think the data is not being read. I tried everything suggested. So broke down the data storing them as individual java bean objects. Is this a possibility?? Rule When $fire : Fire(room != null, status == true) $sprinkler : Sprinkler(room != "") Eval($sprinkler.getRoomId == $fire.getRoomId) //this doesn't work. Anyway I can compare 2 values in my rules???? Then Modify($sprinkler){ setSprinklerStatus(true); } I am trying to check if the fire for the room 1 is true then if sprinkler for that room exists then that is also set true. -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] On Behalf Of rules-users-request(a)lists.jboss.org Sent: Thursday, June 10, 2010 4:57 AM To: rules-users(a)lists.jboss.org Subject: rules-users Digest, Vol 43, Issue 53 Send rules-users mailing list submissions to rules-users(a)lists.jboss.org To subscribe or unsubscribe via the World Wide Web, visit https://lists.jboss.org/mailman/listinfo/rules-users or, via email, send a message with subject or body 'help' to rules-users-request(a)lists.jboss.org You can reach the person managing the list at rules-users-owner(a)lists.jboss.org When replying, please edit your Subject line so it is more specific than "Re: Contents of rules-users digest..."

If you do that, you should not take care of salience. The objects insertion order is not relevant (or, at least, marginally). To notify the session of an object change, you should either put your modifications inside a 'modify' block (see the docs) or let your java beans include a 'PropertyChangeSupport' field (see dynamic facts). In your sample, when the room gets the 'fire' status, the session should be notified of the change, and the sprinkler rule will fire.

Sometimes you can't do this because of constraints on the environment you are work within but in your case you I think you have two options: Each room conceptually has its own sprinkler therefore each Sprinkler object contains a single room field. If a Sprinkler has the concept of operating over multiple rooms then have a Sprinkler object containing its ID and status, then have multiple SprinklerHeadLocation objects containing a reference to the Sprinkler and a single room each. Rule " if fire in room start sprinkler if room has sprinkler" No-loop true when Fire($room : room) SprinklerHeadLocation(room == $room, $sprinklerId : sprinklerId) $sprinkler : Sprinkler(sprinklerId == $sprinklerId, status == false)?? then modify($sprinkler){ setStatus(true) }; End Thomas From: rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] On Behalf Of Esteban Aliverti Sent: 09 June 2010 20:28 To: Rules Users List Subject: Re: [rules-users] depicting array in rules One way could be: when Fire($room : room) $sprinkler : Sprinkler(room contains $room) Room (this == $room, someField == "SomeValue") then modify($sprinkler){ setStatus(true) }; End If you dont have the Room as a Fact Type, then: when Fire($room : room) $sprinkler : Sprinkler(room contains $room) Room (someField == "SomeValue")from $room then modify($sprinkler){ setStatus(true) }; End I'm not 100% sure about this, but at least you can start from here Best 2010/6/9 Fnu Mahalakshmi <FMahalakshmi@nyx.com<mailto:FMahalakshmi@nyx.com >> Hi, Is there any way I can represent an array of values in my rules?? I want to do this: Fire{ Room, Status} Sprinkler{ Object [] Room = new Room[]{new Room(),new room()} Status } Room{ Name, Number} Rule " if fire in room start sprinkler if room has sprinkler" No-loop true when Fire($room : room) $sprinkler : Sprinkler( room == $room) # how can I search through the array of room values here??????? then modify($sprinkler){ setStatus(true) }; End Any Idea if that is possible to implement in rules??? I could do it with adding different instances of sprinkler and rooms. But I want to minimize the amount of repetition in data stored and loaded into the working memory. Any idea??
