[rules-users] Ruleflow and persistence

[vdelbart]

Hello,

I have a problem with this ruleflow :

http://www.nabble.com/file/p12593732/ruleflow.jpg 

This two rules package doesn't work in the same way :

First package :

#created on: 29 août 2007
package reductionExample1

import model.*

rule "global rule"
	ruleflow-group "WorldReduction"
	#include attributes such as "salience" here...
	when
		 $p:Product(year == 2006)
	then 
		#actions
		System.out.println("Global rule");	
		System.out.println("$p.getPrice() : " + $p.getPrice());	
		$p.setPrice($p.getPrice()*1.1);			
end
rule "local rule"
	ruleflow-group "StateReduction"
	#include attributes such as "salience" here...
	when
		$p:Product(year < 2007, $price: price)
	then 
		#actions
		System.out.println("Local rule");
		System.out.println("$price : " + $price);		
		System.out.println("$p.getPrice() : " + $p.getPrice());				
		$p.setPrice($price * 1.2);
end

I have : 
Before : Product(name=Adidas, year=2006, price=100.0)
Global rule
$p.getPrice() : 100.0
Local rule
$price : 110.00000000000001
$p.getPrice() : 110.00000000000001
After : Product(name=Adidas, year=2006, price=132.0)


Second package :

#created on: 29 août 2007
package reductionExample1

import model.*

rule "global rule"
	ruleflow-group "WorldReduction"
	#include attributes such as "salience" here...
	when
		 $p:Product(year == 2006, $priceGlobal: price)
	then 
		#actions
		System.out.println("Global rule");
		System.out.println("$price : " + $priceGlobal);		
		System.out.println("$p.getPrice() : " + $p.getPrice());	
		$p.setPrice($p.getPrice()*1.1);			
end
rule "local rule"
	ruleflow-group "StateReduction"
	#include attributes such as "salience" here...
	when
		$p:Product(year < 2007, $price: price)
	then 
		#actions
		System.out.println("Local rule");
		System.out.println("$price : " + $price);		
		System.out.println("$p.getPrice() : " + $p.getPrice());				
		$p.setPrice($price * 1.2);
end

I have :

Before : Product(name=Adidas, year=2006, price=100.0)
Global rule
$price : 100.0
$p.getPrice() : 100.0
Local rule
$price : 100.0
$p.getPrice() : 110.00000000000001
After : Product(name=Adidas, year=2006, price=120.0)


What is the normal execution (for me the first way) and why is different ?

thanks,

vdelbart
