Best place for bugs is the Guvnor Jira. I opened a ticket for you and I'm

I forgot to answer your other question: I'm on Drools 5.2. I had tried the
Drools 5.3 Beta 1 distribution but there was no improvement- it seems
something was fixed specifically in MVEL 2.1 Beta6.
Also, to Thomas: I have to specify -Xmx512m in order to run a pretty bare
minimum unit test (this doe
I got it directly from the MVEL Web site:

Good luck! Hopefully this version, or an even better one, will be included
with Drools 5.3 final.

In Drools 5 I'm passing in two global Date objects and need to find the

Hi Rob,
Just for you to know in the back a stateless session contains a Stateful
session. The stateless session reduce the number of things that you can do
against it. Allowing you to call just the execute method and automatically
disposing the session.
In the end you will not get any performance i
Hi Rob,
another approach we're considering to version rulesets used to perform
mortgage risk assessment looks roughly as follows:
- each of the rulesets is versioned as a whole (i. e. compile all *.drl
pertaining to a ruleset into a *.pkg file and give this *.pkg a version
number).
- the scoring
Looking for best practice recommendations around the versioning of a rule. Our
application will have 50-60 rule sets comprised of up to 70 rules each. The
activation of many of the rules will be based on a processing date (inserted
fact attribute). The application processing date can be prior
We have a batch application that will have 50 - 60 rule sets, comprised of 5 -
75 rules each. We'll run a group of individuals through the rules and
potentially qualify them for various awards. We'll insert 10 facts, each
containing a unique set of attributes which will be used in the rule se

Hey,
I'm trying to utilize a "load method" for Guvnor, but I can't seem to get it
working. His is my DataHelper class (modeling it off the documentation):
I don't see a Beta6 jar. The one in Drools 5.3 is mvel2-2.1.Beta5.jar -- is
that the one you mean? Are you at drools 5.3 beta1 code level?

For the conditions where a field is tested for equality with some value, the
field name alone is sufficient. So, use [age] rather than [age==]. For other
comparison operators, add the operator, and each value is appended, as
written in a cell below. For more complicated expressions, use an expressi
Hi,
Maybe you can put something like the following in the code:
SpreadsheetCompiler xlsCompiler = new SpreadsheetCompiler();
String drl =
xlsCompiler.compile(ResourceFactory.newClassPathResource("Sample.xls").getInputStream(),InputType.XLS);
System.out.println(drl);
This should enable you to see

Thanks for the explanation Edson!
That's fine. In the meantime we will do our best to pre-compute the most
we can in accumulate() ;-).
Best regards,

Yes, evaluation is incremental, so for every new fact, it will call
accumulate() and getResult().
We do want to reduce the calls to getResult(), improving performance, but
it is not easy to figure out a way, as from an engine perspective, it never

Hi,
It was something that I did not spot immediately, but you also forgot to put
$param in the cells where you evaluate an integer value
marks == $param in stead of marks == blank
But maybe that was something that you already corrected.

About the duplicated $s varaible, is because you have 2 DIFFERENT conditions
saying $s:Student (same thing for $c)
The rules you have there are translated to (when age field has a value):
when
$s:Student (age == 18) //if age value was 18
$s:Student (mark == 20")
$c:College (ranking

Hi,
While testing my custom accumulation function I noticed an unexpected
behavior (th'ats of course a personal point of view).
It seems that Drools 5.1 calls accumulate(...) and getResult(...) as
many times as the number of accumulated facts (accumulate, getResult,

Incremental change set processing might create the effect you describe.
Declared types are always replaced; rules only if they differ.
It sure would be nice if the effects of knowledge base updates were
described in a way that leaves no room for guesswork. "Gimme hope,
