Felipe,

   Ok, this is a nasty damn bug. :(

   I'm working on a solution for it right now. May I ask you please to open a JIRA for it and attach your code bellow?

   Thank you,

2007/7/3, Felipe Piccolini <felipe.piccolini@bluesoft.cl>:

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.
