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 ... ----- Mail original ----- De: "salt" <writemesaltworth(a)gmail.com&gt; À: rules-users(a)lists.jboss.org Envoyé: Mardi 4 Septembre 2012 06:17:16 Objet: [rules-users] Without salience 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.
