hi folks
We are working on a requirement that requires us to have multiple rules that
could fire for a given input and for all the rules that fire, we would want
to cumulate the consequence to reach the final consequence.
As an example, if we want to identify the credit score for a person,
Why not use a Fact that contains your result?
In DRL terms it'd look like this:-
rule one
when
$r : Result( $score : score )
Applicant( numberOfLoans 1 )
then
$r.setScore( $score + 5 );
update( $r );
end
rule two
when
$r : Result( $score :
Thanks a billion mantis!
We do think this would work; let me try it and confirm.

Good idea,
but note that it will only work properly in a stateless session (which
is most likely in his case).
In a stateful session, with multiple fireAllRules and when the
applicant's properties change between those fireAllRules call,
the trick is to do an insertLogical of a ScoreDiff

Guvnor is localised to the following locale:-

The default language for messages etc when no locale is provided (or is

Hi - I am a Drools newbie and I apologize in advance if the answer to my

Hi all,
I encountered the following issue:

Probably it is because you are using NOT (). The engine will not fire this

Hi,
If you do not want to check for all alternative cases, you might need a
showstopper to stop the firings of unwanted rules.
This can be achieved by executing insert(new ShowStopper() ); in your RHS.
All LHS of the rules will check for not( ShowStopper() )
Alternatively, you can use the new

Sorry, but I fogot about you :-(.
It does not work because both wolfgang and I did get your question wrong.
If I were you, I would try to work from the opposite direction and check

As an aside note. You may want to consider re-working your rules to never use
the || condition.
It's not that this is inherently bad, but that the any logical ORs mean that
you are actually representing more than one rule within the singular rule.
This can make mapping the logic to the

Hi,
you might try something like one of the following two variants:
a) Checking for Location only first, inserting a Fact for the respective
location and doing a second rule for each location that checks for this fact

If you know that your export is good, then you could backup the directory that

Then start guvnor with an empty repository -- this will force guvnor to
initialize the repository.
Next simply launch Guvnor, and import your

I use database as the store for assets. I was thinking of asking DBA's to
