[rules-users] Without salience

[Vincent LEGENDRE]

If it works with salience, why change ? 
And why is the order so important ? Still trying to get the first occurence of an event of a given type/value ? 
It remembers me some not-so-old post ...

Hi All, 

For the below use case i have implemented the rule. Please suggest other way 
of doing without salience. 

scenario 

ITEMS AMOUNT OCCNO 

PASS 10 1 

FAIL 10 2 

PASS 15 3 

PASS 25 4 


rule "HelloWorld_14" 
salience (65522- $list.indexOf( $transdet1 )) 
when 

$p1:Passes($list : transaction) 
$trans1:Transaction(items in ("PASS")) from $list 
$p2:Passes() 
not(exists($transdet5:Transaction(items in 
("FAIL"),value==$transdet1.getVaue(), occno>$trans1.getOccno()) from 
$p2.transaction)) 
then 
System.out.println($trans1.getOccno()); 
end 

The above will return 

3 

4 (not 4,3) 

Kindly suggest other way of doing this without salience. 


Thanks 
Salt
