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?
Any help is appreciated greatly.

Try setting the second rule with a higher salience value?

How do we do that? Since we are using the rules server, all we are doing is
calling with an HTTP call with the object and the rules flow we want to
call. We then receive back the results as the HTTP response.

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.

Did you read any of the Drools Expert documentation? The necessity of
informing the inference engine about changes of fact objects is indeed
discussed, and all three techniques of doing that are covered.

Did you read any of the Drools Expert documentation? The necessity of informing the
inference engine about changes of fact objects is indeed discussed, and all three
techniques of doing that are covered.

Can you please provide the syntax or point me in the direction of an example?

It's done in the rule action of the first rule. If you don't inform the engine
that the object has updated the second rule can't know about it.

How do we do that? Since we are using the rules server, all we are doing is calling with
an HTTP call with the object and the rules flow we want to call. We then receive back the
results as the HTTP response.

Did you notify the engine that your data has been updated?

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?
Any help is appreciated greatly.
