Could you not change your rule? rule "An item is in the office" salience 0 when $item : Item( ) $container : Container(location.name = "office", items contains $item) then System.out.println("item in office"); end
[I think] this would only require an update to the Container. If a object represented by a patten changes you always need to update the working memory's knowledge of the object. The above requires that Container exposes an Items collection. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Edson Tirelli Sent: 24 October 2007 00:58 To: Rules Users List Subject: Re: [rules-users] Rules firing with an update of another object Hi Fabrice, That is how it is supposed to work... no "automatic" way of doing it in another way. []s Edson 2007/10/23, Fabrice Granzotto < [EMAIL PROTECTED]>: Hi everybody! Here is my code and my rule. The problem is that the rule doesn?t detect that my item ?chocolate? contained in the container has moved to the ?office?. I know that if I update the item instead the container it?s working, but I was wondering if there is a solution to detect this movement by this way? Do you have a solution? Thanks! *******CODE ******* session = ruleBase.newStatefulSession(); Location kitchen=new Location("kitchen"); Location office=new Location("office"); Container container1=new Container("container1",kitchen); session.insert(container1); Item chocolate=new Item("chocolate", container1); session.insert(chocolate); session.fireAllRules(); //No rules fired => OK container1.setLocation(office); session.update (session.getFactHandle(container1), container1); session.fireAllRules(); //Once again, no rules fired => Not OK... I want detect this movement *******RULE ******* rule "An item is in the office" salience 0 when $itemA : Item($cont : container, $cont.location.name=="office") then System.out.println("item in office"); end _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users <https://lists.jboss.org/mailman/listinfo/rules-users> -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com
