[rules-users] Problem with update(fact)

I know I already asked this in a previous email, but no answer and diferent subject... so I'll ask again I have an issue using update in 2 rules that update the same object... a loop is created even when I try to avoid the loop adding an extra condition to each rule... Im inserting an ArrayList as a fact too, so I can check the extra condition... Can anyone tell me how to fix this? Consider this: //-------RULES----------------------------- package cl.bluesoft.test #list any import classes here. import java.util.List import java.util.ArrayList import cl.bluesoft.test.rules.Fact #declare any global variables here rule "test update A" salience 699 no-loop when $f : Fact($n: number > 0) $list: ArrayList( this excludes "key1") then System.out.println("A-fact number1:"+$f.getNumber()+" list 1:"+$list); $list.add("key1"); $f.setNumber($n + 1); update ($f); update ($list); System.out.println("A-fact number2:"+$f.getNumber()+" list 2:"+$list); end rule "test update B" salience 699 no-loop when $f : Fact($n: number > 1) $list: ArrayList( this excludes "key2") then System.out.println("B-fact number1:"+$f.getNumber()+" list 1:"+$list); $list.add("key2"); $f.setNumber($n + 1); update ($f); update ($list); System.out.println("B-fact number2:"+$f.getNumber()+" list 2:"+$list); end //-------FACT----------------------------- public class Fact implements Serializable { private static final long serialVersionUID = 331627137981862975L; private int number; public Fact(int number){ this.number = number; } public Fact(){ this(0); } /** * @return the number */ public int getNumber() { return number; } /** * @param number the number to set */ public void setNumber(int number) { this.number = number; } } //------TEST--------- public class TestUpdateFact implements Serializable { private static final long serialVersionUID = -574789596641083743L; /** * @param args */ public static void main(String[] args) { RuleBase ruleBase = RuleBaseFactory.newRuleBase(); Package pkg = builder.getPackage(); .... WorkingMemory session = ruleBase.getStatefulSession(); ...etc etc... List list = new ArrayList(); Fact fact1 = new Fact(1); session.fireAllRules(); ....etc, etc... } } //--------OUTPUT------------ A-fact number1:1 list 1:[] A-fact number2:2 list 2:[key1] B-fact number1:2 list 1:[key1] B-fact number2:3 list 2:[key1, key2] A-fact number1:3 list 1:[key1, key2] A-fact number2:4 list 2:[key1, key2, key1] B-fact number1:4 list 1:[key1, key2, key1] B-fact number2:5 list 2:[key1, key2, key1, key2] A-fact number1:5 list 1:[key1, key2, key1, key2] A-fact number2:6 list 2:[key1, key2, key1, key2, key1] B-fact number1:6 list 1:[key1, key2, key1, key2, key1] B-fact number2:7 list 2:[key1, key2, key1, key2, key1, key2] A-fact number1:7 list 1:[key1, key2, key1, key2, key1, key2] A-fact number2:8 list 2:[key1, key2, key1, key2, key1, key2, key1] B-fact number1:8 list 1:[key1, key2, key1, key2, key1, key2, key1] .... for ever..... So I have a loop... only when I use update and both rules... condition about the list not containing "key1" and "key2" seems not properly chequed... I dont know... Can somebody help me? Am I missing something here? Thanks. Felipe Piccolini M. felipe.piccolini(a)bluesoft.cl
