Hi, I have a problem when updating fields in rules : Here's the rule : when t : Bill($amount : totalAmount, totalAmount > (new Double(150.0).doubleValue())); then System.out.println("tot : " + $tot); end The original totalAmount is 200. A fact update sets the totalAmount at 100 (with an update of the facthandle that I can see in the debugger of the working memory) so the condition of the rule does not be true. Nevertheless, the System.out is made and prints 100. I use Statefull session and set shadow facts to true. Thanks for helping me ! _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Not addressing your stated problem, but I have one question: why are you using this expression: "new Double(150.0).doubleValue()" Why not just use "150.0"? --- On Mon, 3/16/09, thomas moncieu <thomas.moncieu(a)gmail.com&gt; wrote: > From: thomas moncieu <thomas.moncieu(a)gmail.com&gt; > Subject: Re: [rules-users] Problem with updated facts > To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; > Date: Monday, March 16, 2009, 9:39 AM > Hi, these are the rules : > > Rule A : > > rule "ID_15202" > ruleflow-group "RG_A" > when > i : Item(name=="cheese") > t : Bill(anItem==i); > then > t.setAmount(t.getAmount() - 100); > update(t); > end > > Rule B: > > rule "ID_15203" > ruleflow-group "RG_T" > when > t : Bill($amount : totalAmount, totalAmount > (new > Double(150.0).doubleValue())); > then > System.out.println("tot : " + $tot); > end > > It gives the correct result if shadow proxy is turned on. > > But all the rules are re-evaluated with the update(t).

You lost the rest of the thread, i.e. original questions, Thomas. What was the original problem again? Also, Which ruleflow-group comes first, A or T? And if u don't want the same rule to re-activate itself, you no-loop true. If u don't want a rule within the same ruleflow-group to re-activate others, use lock-on-active true 2009/3/16 thomas moncieu <thomas.moncieu(a)gmail.com&gt; Hi, these are the rules : > > Rule A : > > rule "ID_15202" > ruleflow-group "RG_A" > when > i : Item(name=="cheese") > t : Bill(anItem==i); > then > t.setAmount(t.getAmount() - 100); > update(t); > end > > Rule B: > > rule "ID_15203" > ruleflow-group "RG_T" > when > t : Bill($amount : totalAmount, totalAmount > (new > Double(150.0).doubleValue())); > then > System.out.println("tot : " + $tot); > end > > It gives the correct result if shadow proxy is turned on. > > But all the rules are re-evaluated with the update(t).
