Anyone Using Scorecards in a Spreadsheet?
by Steven Núñez
Hello Droolers,
Is anyone out there using scorecard spreadsheets? I'm trying to, ideally, import a PMML scorecard model, but in lieu of that can export a spreadsheet from the modeling tool and massage that. Trouble is I can't find anything in the 5.5 docos that describe the format that the spreadsheet is supposed to be in.
Does anyone have any pointers to the scorecard spreadsheet format?
Regards,

Re: [rules-users] Bomb when calling Drools with PKG containing a process
by David Shields OpenCDS
Problem resolved. I inadvertently left a Maven Dependency pointing to jBPM
5.3 instead of 5.4.

Subject: Bomb when calling Drools with PKG containing a process
I have been trying to upgrade our application to Drools 5.5 from Drools 5.4.
I rebuilt several knowledgeBases containing processes with Drools 5.5, but I
can't get them to run. I can get a simple DRL file that does not reference
any processes to run just fine. Both the DRL and the KBs use
statelessSessions. The program has been used for a couple years, and has
been modified to run with Drools 5.1.1, 5.3, 5.4, and now 5.5, and has been
supporting processes since Drools 5.3 / jBPM 5.2.
Here is the bomb that I get:
OpenCDS call to Drools.execute failed with error: Unexpected exception

org.jbpm.process.instance.event.DefaultSignalManager$SignalAction@5cd5a2a9
org.drools.common.AbstractWorkingMemory:executeQueuedActions:995

I have single-stepped through the code with Eclipse, but I can't quite
figure out what is wrong with my KBs. They ran just fine on Drools 5.4
(although there was a memory leak in Drools with that version), and the only
thing I changed was to populate the "probability" value on the BPMN-Diagram
(because it wouldn't validate without it).
The program builds a command list, and executes it with the following:
ExecutionResults results = null;
try {
results =
statelessKnowledgeSession.execute(CommandFactory.newBatchExecution((cmds)));
} catch (Exception e) {
String err = "OpenCDS call to Drools.execute failed with error:
" + e.getMessage();
log.error(err);
StackTraceElement elements[] = e.getStackTrace();
for (int i = 0, n = elements.length; i < n; i++) {
String detail = elements[i].getClassName() + ":" +
elements[i].getMethodName() + ":" + elements[i].getLineNumber();
log.error(detail);
err += "\n" + elements[i].getMethodName();
}
throw new DSSRuntimeExceptionFault(err);
}
Has anybody seen this error before?
Thanks for any ideas or suggestions!

Stateless session dis-associating listeners after first execute call. Bug or a feature?
by Michal Bali
Hello,
I am using a stateless session. First I add an agenda event listener. When
I first call session.execute(Itelable) all works as expected. However when
I call it the second time (without adding the listener again) the listener
does not seem to be called at all.
However note that when I call session.getAgendaEventListeners() the event
listener is always there.
IMHO I am guessing that the 'dispose' method that is called behind the
scenes possibly dis-associates the event listener.
I've tested this with 5.5.Final. BTW This worked fine with Drools 5.0. I
haven't checked later versions.
I wonder is this a bug or a feature?
Isolated test case is attached.
Thank you.
Best regards,
Michal

proble with localSearch

Hi,
I'm trying to implement a basic local search (really new to it).
When I run my project I now get:

Alert( $caseNumber : caseNumber, $alertNo: alertNo )
not Alert( caseNumber == $caseNumber, alertNo < $alertNo )
$list : List( ) from collect($alert : Alert( caseNumber ==
$caseNumber))
then
System.out.println("******Printing list******: ");
System.out.println("******List hashCode: " + $list.hashCode());
for(Object o : $list){
System.out.println(o);
}
I then declare a fact CaseList with a property with name value and type
List, each time a new List is collected, I create a new CaseList and set
this list on this intance and logically insert this intance
CaseList caseList = new CaseList();
caseList.setValue($list);
insertLogical(caseList);
end
Sample output
******Printing list******:
******List hashCode: 342532614
Alert [caseNumber=1022621, alertNo=6]
Alert [caseNumber=1022621, alertNo=6]
Alert [caseNumber=1022621, alertNo=6]
Alert [caseNumber=1022621, alertNo=2]
Alert [caseNumber=1022621, alertNo=1]
Alert [caseNumber=1022621, alertNo=2]
Alert [caseNumber=1022621, alertNo=2]
Alert [caseNumber=1022621, alertNo=8]
******Printing list******:
******List hashCode: 890817600
Alert [caseNumber=1021567, alertNo=1]
Alert [caseNumber=1021567, alertNo=2]
Alert [caseNumber=1021567, alertNo=8]
******Printing list******:
******List hashCode: -1376001294
Alert [caseNumber=1012283, alertNo=1]
Alert [caseNumber=1012283, alertNo=2]
Alert [caseNumber=1012283, alertNo=6]
Alert [caseNumber=1012283, alertNo=2]
Alert [caseNumber=1012283, alertNo=8]
Alert [caseNumber=1012283, alertNo=2]
******Printing list******:
******List hashCode: -1069600305
Alert [caseNumber=55506677, alertNo=1]
Alert [caseNumber=55506677, alertNo=2]
Alert [caseNumber=55506677, alertNo=6]
I then have a different rule that checks for any CaseList objects in working
memory and needs to interrogate each instance and collected list to see
whether the list contains an alert with alertNo == 4 or 5 or 6 and does not
contain an alert with alertNo == 7 or == 8 and then creates a new inferred
fact HighPriority if this is the case which other rules act on.
I use the following rule to be able to do this logic and expect a single
HighPriority intance in working memory but there are several, am I doing it
wrong,
rule 'Determine if High priority'
dialect 'java'
when
$a1 : Alert( alertNo == 4 || == 5 || == 6 )
$a2 : Alert( alertNo == 7 || == 8 )
$m : CaseList( value contains $a1 && not contains $a2 )
then
HighPriority hp = new HighPriority();
hp.setValue(true);
insertLogical(hp);
end

Guvnor only: NullPointerException AfterEvaluator.evaluateCachedRight
by kappert
Version 5.5.0.Final (Guvnor and libraries)
We are seeing the NPE with the stack trace given below, but only when
loading rules through Guvnor. Same rules file and code runs fine without
Guvnor, but error with Guvnor.
*With Guvnor:* KnowlegdeBase from KnowledgeAgent using changeset.xml,
scanner running for on-the-fly rule updates in Guvnor.
*Without Guvnor:* kbuilder.add(new ClassPathResource("Rules.drl",
getClass()), ResourceType.DRL);
I have only little experience with Drools and would appreciate advice on how
to approach this problem.
Could it be something in the rules file itself?
But why would it make a difference whether the rules came from Guvnor or a
file?
Could the error point to something missing from the POJO model in Guvnor? I
am still in the process of determining what should go in the JAR file
exported from Eclipse and what not. The rules validate OK in Guvnor though,
and the package can be built.
What else to consider?
A similar problem was discussed here
<http://thread.gmane.org/gmane.comp.java.drools.user/15285> , but the
solution seems to have been an upgrade to version 5.

Purpose of difficultyWeightFactoryClass in @PlanningEntity annotation.
by Michiel Vermandel
Hi,
I am struggling with the purpose of difficultyWeightFactoryClass in the @PlanningEntity annotation.
I thought it was used to indicate which PlanningEntities to handle first in order to get faster to a solution.
Though it seems that it also has impact on whether or not to get to a zero-hardscore solution.
I mean I have a testcase that resolves to a zero-hardscore solution.
Then I change something small in how the difficultyWeightFactoryClass calculates the weight and all the sudden I get a negative-hardscore solution.
I thought it would still get to the same zero-hardscore solution but in a shorter solving time.
My solver termination is as follows:
<termination>
<terminationCompositionStyle>OR</terminationCompositionStyle>
<maximumSecondsSpend>3600</maximumSecondsSpend>
<scoreAttained>0hard/0soft</scoreAttained>
</termination>
and constructionHeuristic:
<constructionHeuristic>
<constructionHeuristicType>BEST_FIT_DECREASING</constructionHeuristicType>
</constructionHeuristic>
I do not reach a zero-hardscore and the time spent is about 2.8 seconds...
If I read the best solution I get:
.isEveryProblemFactChangeProcessed(): true
.isTerminateEarly(): false
Any idea why I do not get a zero-hardscore solution anymore when only making a small change to the difficultyWeightFactoryClass logic?
Thanks
Michiel.

How do you use packages in Guvnor?
by dunnlow
I've been using Guvnor for a while (on v5.4) now. However, I've always had
everything in one "package." As my project grows however I am looking to
improve the organization of my assets - it is getting harder and harder for
me to find in Guvnor the rule I am looking for. As I looked into this it
occurred to me that I don't really understand the concept/purpose of a
package.
For example, I have a main package, "Auto" that contains generic
rules/assets for automobiles. I have assets specific to types of autos, so
I created packages "Auto.Compact" and "Auto.Sedan". Those packages are
created neatly under the Auto Package. However, when I looked at the source
for Auto, I expected to see the source for assets in Auto, Auto.Compact and
Auto.Sedan, but it only contains the source for Auto (rather than having
them rolled up).
I'm a java developer, so I expected the same sort of "package"
functionality; all of the sub packages being contained within the main
package.
FYI, I have a drools server that connects to Guvnor to obtain/create the
most recent rule base.
I have Drools Dev Cookbook, and looked through the online guide, but didn't
really find anything to help.
Can anyone explain to me the purpose/intention of a package (or point me to
some good documentation about it).
Any best practices out there on how to organize assets.
Thanks very much,
-J
