Re: [rules-users] I want only first rule to be executed even more than one rule are fulfilling the LHS

Lindy, "my understanding is that if you have 10 rules under same activation group always the one with high salience will fire ignoring other rules. (correct me if i am wrong.)" The rule with the highest salience ***that matches (i.e., in your words: is satisfied)*** will be fired and the others will be canceled, so I guess that is exactly what you are looking for. If I misunderstood your case, please explain it further.
