Re: [rules-users] Object updated as rules are running
Try setting the second rule with a higher salience value? 2011/2/25 Jon Gil jonsprogrammingem...@gmail.com: Hi, I have a very simple rules flow that I am getting odd results from. For now, our project is planning on using spreadsheets and a drools server. The test project we are working on accepts a movie name from an external source and creates a Movie object that is passed to the rules. The first rule looks at the movieName attribute and assigns it a movieStar using the Movie objects setMovieStar call. We have printLn statements before and after this action to confirm that it does in fact work. The second rule, where things go wrong, checks the MovieStar attribute, but no matter what we've just set it to, it always uses the value (NoStarYet) that was originally created when we create the Movie object in our Java code in the condition of our second rule. We've tried using the getMovieStar call in the condition, but it has been throwing errors when we startup the Drools Server. When we retreive the Movie object from the resultSet, the movieStar attribute is set correclty, but we can't get our flow to go as expected. This really seems like a simple issue, but we've had no luck with it. Any thoughts? Does the rules engine use the getter methods for conditions or does it use the values from the entityXML we pass in? Is there a way to make the engine update the object between running each rule?

Re: [rules-users] Object updated as rules are running
Title: CARTE DE VISITE
To notify modifications, use "update" operator. This action will
notify all rules using this object instance to re-evaluate. So the
second rule will trigger, but also the first one if you don't check
that MovieStar has its default value in your conditions. Without
this check, you will fall in infinite loop.
You should read the documentation more carefully.
Your question is on very basic concepts of a rule enine.
