KnowledgeAgent exception while migrating from 5.4 CR1 to 5.4 final
by sumatheja
Hi,
I've a drools application running on drools 5.4 cr1. It was working fine
until I migrated to 5.4 final. Now When I try to get the
StatefulKnowledgeSession from the Guvnor(5.4 final) I get the following
exception

However, when I replace the drools-core-5.4 final jar with
drools-core-5.4-CR1 jar (just the one jar, leaving the remaining jars as it
is) everything works fine again. Any idea If I'm missing something here?
I'm using
1> Drools-guvnor 5.4 final
2> Drools Expert 5.4 Final
3> jbpm 5.3 final
Any help is much appreciated.Thanks in Advance.

Accumulate function
by Matteo Cusmai
Hi all,
i am going to use a custom accumulate function like that:
rule "CrowdInAreaEvent-event"
no-loop
when
$RFIDReader : SensorFixed(type == Sensor.SENSOR_TYPE_RFID,
$coverageArea : areaOfInterest )
not CrowdInAreaEvent( sensor == $RFIDReader, this meets[ 5s ] $obs )
$count : Integer( intValue > 10 )
from accumulate( $obs : RFIDObservation( $tagid : tagid, sensor
== $RFIDReader )
over window:time( 60s ) from entry-point lowLevelSensorStream,
countDistinct( $tagid ) );
then
insert( SituationManager.createCrowdInAreaEvent( "Crowd, number
people: " + $count, Event.THREAT_LOW, $coverageArea, $RFIDReader, $count,
60, 10 ) );
end
I need to refer $obs object in order to compare timing of new observation
with last event. Is it possible to do that?
Thanks a lot,
Matteo.

[Planner]Sudoku solver
by Qchevalier
Hi everybody,
In order to understand better Planner, I did a sudoku solver. I was inspired
by Queens example.
I need 3 minutes to solve a sudoku with localSearch .
*I have 2 issues :*
1- Construction Heuristic doesn't work at all : I don't understand why.
2- I use FROM_PLANNING_ENTITY_PROPERTY for my @PlanningVariable. The
@ValueRange is a collection of Value : [value1, value2, value3, value4,
value5, value6, value7, value8, value9]. => But this range isn't used in the
localSearch. Instead I think localSearch uses the value list
FROM_SOLUTION_PROPERTY.
I share my code on GitHub : git@github.com:qchevalier/Sudoku-solver.git
*[To understand my code]*
Firstly I use the API configuration : you will have to change the path of
the drl file in App.java(line 36), and put away the xml configuration file.
A sudoku is composed by 81 digits : each digit has 1 value, 1 column, 1 row
and 1 block.
1 value has a value between [1-9] (Value can be initialized; in this case
they can't be changed during solving. 0 is undefined value and has to be
changed).
1 column has an index with a value between [0-8].
1 row has an index with a value between [0-8].
1 block has an index with a value between [0-8].
http://drools.46999.n3.nabble.com/file/n4005002/sudoku_how_to.png
In order to initialize the sudoku I use methods initTab* from
NDigitsGenerator.java .
After get it on github (git@github.com:qchevalier/Sudoku-solver.git ):
In order to run the application : import it in eclipse, modify the path of
the DRL file, and then run as java application "App.java".
*A sample of the execution can be as this : *

Guvnor - support for custom file extensions
by anchi
Hi!
I need to extend Guvnor to support custom file extensions for BPMN
processes. So instead of using "/.bpmn/" or "/.bpmn2/" we need to use our
own file extensions. At the moment Guvnor just assumes them the to be /Other
assets/ and ignores them when building a package.
I plan to change Guvnor source to achieve this. I would appreciate if I get
some guidelines from dev-team, what classes do I have to change. Since you
have recently been adding support for "/.bpmn2/" extension, I guess you
could give me some hints.
I found out that I have to add my extensions to
/org.drools.guvnor.client.common.AssetFormats/, change
/org.drools.guvnor.server.builder.AssetItemValidator/ and
/org.drools.guvnor.server.verification.AssetVerifier/ . Is there something
else?
Thanks!

Object activiates same rule many times
by Christina Lau
Hi all,
I find an odd pattern in the audit log. When an Object is inserted to the
working memory, activation is created many times on same rule. The more
objects are inserted, the duplicated activations are growing exponentially
which degrade the performance a lot.
Here attached part of the audit log:
http://drools.46999.n3.nabble.com/file/n4000630/rule-DOCSEP-1337325521971...
rule-DOCSEP-1337325521971.log
In the log,
- when object (130) is inserted, rule "C020 - Gate charge (Out M)-B" is
activiated 129 times.
- when object (131) is inserted, rule "C020 - Gate charge (Out M)-B" is
activiated 130 times.
Here is the rule of "C020 - Gate charge (Out M)-B",
The "insert" in RHS only add ChargeDetailRefSeqEntity to working memory that
I don't think it causes the recursive activation.
And I'd already set no-loop to true. Does anyone offer some help here?
Thank you very much,
Christina

Drools verifier - redundancy detection
by bitter
I would like to use drools-verifier to detect redundancy in my drl files. But
drools-verifier can not detect redundancy even in simple drl. Maybe I do
something wrong ;/.
*Simple drl file:*
rule "rule 1"
when
$person: Person(age==16, name=="Anna")
then
retract($person);
end
rule "rule 4"
when
$person: Person(age==16, name=="Anna")
then
retract($person);
end
*And my test:*
@Test
public void verifyRules() {
//given
VerifierBuilder vbuilder = VerifierBuilderFactory.newVerifierBuilder();
Verifier verifier = vbuilder.newVerifier();
verifier.addResourcesToVerify(new
ClassPathResource("qualityVerification.drl", getClass()), ResourceType.DRL);
if (verifier.hasErrors()) {
for(VerifierError ve : verifier.getErrors()) {
System.out.println(ve.getMessage());
}
throw new RuntimeException("ERRORS ");
}
//when
verifier.fireAnalysis();
//then
VerifierReport report = verifier.getResult();
System.out.println(">>>>>>>>> ERRORS: ");
for(VerifierMessageBase vmb : report.getBySeverity(Severity.ERROR)) {
System.out.println(vmb + ". Type: " + vmb.getMessageType());
}
System.out.println(">>>>>>>>> WARNINGS: ");
for(VerifierMessageBase vmb : report.getBySeverity(Severity.WARNING)) {
System.out.println(vmb + ". Type: " + vmb.getMessageType());
}
System.out.println(">>>>>>>>> NOTES: ");
for(VerifierMessageBase vmb : report.getBySeverity(Severity.NOTE)) {
System.out.println(vmb + ". Type: " + vmb.getMessageType());
}
System.out.println(">>>>>>>>> MISSING RANGE: ");
for(MissingRange mr : report.getRangeCheckCauses()) {
System.out.println(mr);
}
}
*OUTPUT:*
>>>>>>>>> ERRORS:
>>>>>>>>> WARNINGS:
Warning id = 0:
faulty : LiteralRestriction from rule [rule 4] value '== Anna'
Rule base covers == Anna, but it is missing != Anna
Cause trace:
. Type: MISSING_EQUALITY

Warning id = 3:

>>>>>>>>> NOTES:

Gap: (Field 'age' from object type 'Person') Operator = '<' 16 from rule:
[rule 1]
Gap: (Field 'age' from object type 'Person') Operator = '>' 16 from rule:
[rule 1]
Is it a bug or I do something wrong?
