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,
Edson
2007/7/3, Felipe Piccolini < [EMAIL PROTECTED]>:
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.
