Re: [rules-users] Ascending sort by salience results in NPE

rule "process Token" salience - $prio // by ascending x25No values when $token: Token( $x25No: x25No ) // match on int x25No $elem: ElemType( $prio: x25No == $x25No ) then retract($token); end All versions 5.[2345].0 crash. Using "0 - $prio" is a workaround.
