Re: [rules-users] No-loop \ salience issue - could somebody explain?

Hi, I've noticed some "interesting" behaviour with the use of no-loop and salience that I wonder if anybody can explain to me? Given the following rules:- *package* drools.debug *rule* "Rule 1- (Fired)" //salience 500 *no-loop** true* *when* $m : Machine ( ) *then* System.out.println("DEBUG [Rule 1-]---> Do nothing!"); *end* *rule* "Rule 1a (Fired)" //salience 400 *no-loop** true* *when* $m : Machine ( ) *then* System.out.println("DEBUG [Rule 1a]---> Setting Attribute(\"TEST3\") on Machine"); Attribute a =* new* Attribute("TEST1", 100); $m.setAttribute(a); * modify*($m); * assert*(a); *end* *rule* "Rule 1b (Fired)" //salience 300 *no-loop** true* *when* $a : Attribute( name == "TEST1" ) $m : Machine ( attribute == $a ) *then* System.out.println("DEBUG [Rule 1b]---> Found!"); *end* Assuming only one Machine Fact is present in Working Memory and the salience lines above are commented out "Rule 1- (Fired)", "Rule 1a (Fired)" and "Rule 1b (Fired)" are activated and fired once (and once only). If however the salience values are uncommented rule "Rule 1- (Fired)" is fired twice (even though it is has the "no-loop" attribute). If the salience statements remain but have the same value then the rules only fire once as well (as I'd expect). It appears that "no-loop" only applies to rules with the same salience. Is this correct? Can somebody provide some reason as to why this occurs as it is different to what I'd expect?
