[rules-users] Same rules applies twice

Hi I use Drools 5.01 I have the following rules: rule "Reload test" salience 10000 when $result: Result( $resultId:resultId) not (exists Test(resultId.technicalId==$resultId.technicalId)) then Test test = createTest($resultId); insert(test); end When I insert two results with the same identifier, rules is applyed 2 times. One for each result. I do not understand why. Do you have an idea of what's happen and how to guratantee that myl rules will not be applied twice. Here order is not important ... Thanks
