Is this an appropriate approach
by ronalbury
The issue I have been struggling with is ordering rule evaluation ... which I
realize violates one of the theoretical underpinnings of a rules system. I
receive all String data. I wanted to test if the data was well formed (via
regular expressions) prior to testing the semantic values stored in the data
(e.g. numbers, etc).
However, I woke up this morning, smacking my forehead, wondering why I
didn't think of this earlier. Is there any reason I shouldn't run the rules
engine twice - once with a knowledge base containing the regular
expressions, and then (if it passes) run it through a different knowledge
base with the semantic evaluations?

Planner 5.3.Final - "presumedScore is corrupted" when using "update" on the rules working memory
by guyramirez
I am looking into Planner for a schedule assignment business case.
I created a move factory, got the local search phase set up and quicly ran
into a "presumedScore is corrupted because it is not the realScore" error.
As a work around, I changed my Move::doMove(..) implementation to "retract"
then "insert" rather than "update" the new updated planning entity and the
issue went away.
Then I worked on setting a construction heuristic and I again ran into the
same error. By applying a local code patch to the
PlanningValueWalker::changeWorkingValue(..) method to also "retract" and
"insert" rather than "update" also fixed the issue.
I also tried to correctly implement the hashCode() and equals(..) methods on
my planning entity (as mentioned in Drools Expert documentation) as well as
use the default implementation of those methods (as in the nurse rostering
example) with the same unsuccessful results.
I must mention than I am able to run the nurse rostering example without any
issues.
Could someone maybe point me to the right direction on why "update" does not
work for me? I can provide detailed information if needed.
Thanks,
Guy

XSD resource type
by Radovan Synek
Hello,
I am trying Spring - Drools integration and in the documentation I found this line:
<drools:resource source="classpath:org/drools/container/spring/model.xsd" />
(section 2.1.1.4. Define a KnowledgeBase, example 2.2)
I also realized that XSD resource type is present in the resourceTypeEnum (drools-spring.xsd).
Could I ask you where to find more information about this resource type?
Best regards,
Radovan Synek

Re: [rules-users] 'else' in rule
by Spyros Sakellariou
I fully agree with Jim K.
Writing good business rules (and in my opinion good business rules are loosely coupled) is not straightforward and intuitive at the beginning and requires from software engineers to develop a different mindset.
Having an ELSE statement could be a deterrent from writing loosely coupled rules which is a good practice IMHO. It reminds me of my early BASIC programming days (in the 80's :) where I would end up with horrible spaghetti code because of my misuse of the infamous GOTO statement.
I also vote against the ELSE statement.

Subject: Re: [rules-users] 'else' in rule
My $.02
I'm early in my use of Drools and Rules and struggled at first with the lack
of ELSE. At first I would frequently feel "an ELSE would be prefect here".
After awhile I believe that NOT having Else is a good thing. As I get
better with writing rules I find that most of the times when I think I need
an Else it usually means I should take a closer look at the rule.
If I have a true Else situation for me I put the two rules one right after
another. In these situations I think it is better to have to write the
"ELSE" rule as effectively a NOT of the WHEN rule then having an ELSE fall
through. Isn't that much extra coding and usually gives me pause to give it
one more evaluation to see if this is a true ELSE or a new rule with similar
criteria from the When.
Many times the ELSE covers too many possibilities that should be explicitly
checked and for me at least tells me I might not have fully broken the
requirements down. As another posting indicates the complexity of
implementing it I also wonder about the performance hit the logic to allow
for an ELSE would add.
With my current understanding of business rules and drools I would vote
against an ELSE.
Jim K.

Drools Ruleflow: java.lang.OutOfMemoryError!
by victorC
Hi folks,
I am getting java.lang.OutOfMemoryError while running very simple process
containing just one HumanTask node.
I cannot get what I am doing wrong. I've setup everything according the docs
(http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-flow/html...)
My setup is:
JBoss 4.2.3.GA
Hibernate 3.2.4.sp1
JBoss Seam 2.2.0.GA
Drools 5.1.1
MySQL 5.1.41 / mysql-connector 5.0.7
Drools Ruleflow persistence: JPAKnowledgeService, MySQL,
JBossTransactionManager
The stacktrace is as follows:
javax.persistence.PersistenceException: java.lang.RuntimeException:

'else' in rule
by snehils
Hi All,
I want to take action when the condition in WHEN fails. Something like as
follows:
WHEN
<Condition>
THEN
<Action>
/ELSE
<Action when Condition fails>/
Is it possible to have else part in rule? Or I have to make another rule for
failed condition?
I am using Drools 5.1.0 version.
