Re: [rules-users] [rules-dev] [BAD Bug] incorrect evaluation of LHS using Integer/Number intValue
I just fixed this bug on the master and backported it on the 5.5.x branch.
Wolfgang, thanks again for your help.

This is a self-contained DRL demonstrating the erroneous handling of

but works correctly with 5.4.0 and previous versions.

I am new to Drools and am trying to get the sample program to work.
This
sample is given in the drools documentation
http://docs.jboss.org/drools/release/5.5.0.Final/drools-expert-docs/html_single/index.html#d0e9542
.
This drool rule is expected to sort integers. I just changed the
numbers
from what are given in the sample and they do not get sorted as
expected.
Tried using drools version 5.5.0, 5.5.1 and the master 6.0.0, but got
the
same wrong results.
Following is the main code:
package com.sample;
public class Example2 {
public static void main(String[] args) throws Exception {
Number[] numbers = new Number[] { wrap(5), wrap(6), wrap(4),
wrap(1), wrap(2) };
new RuleRunner().runRules(new String[] { Example3.drl },
numbers);
}
private static Integer wrap(int i) {
return new Integer(i);
}
}
The RuleRunner class is the same as given in the example and I do not
think
I should give that here, since it will clutter the question. It simply
creates the KnowledgeBase, stateful session, inserts the facts as
given
in
the 'numbers' array above and then calls fireAllRules method on the
session.
The rule file (Example3.drl) is:
rule Rule 04
dialect mvel
when
$number : Number()
not Number(intValue $number.intValue)
then
System.out.println(Number found with value: +
$number.intValue());
retract($number);
end
The output I get is as follows:
Loading file: Example3.drl
Inserting fact: 5
Inserting fact: 6
Inserting fact: 4
Inserting fact: 1
Inserting fact: 2
Number found with value: 1
Number found with value: 4
Number found with value: 2
Number found with value: 5
Number found with value: 6
Not the correct expected ascending sorted order.
What might I be doing wrong? I cannot imagine that the drools rule
engine
would be broken at this basic level.

Re: [rules-users] can't copy files to guvnor using webdav
Thanks Jervis, In that case, it sounds like the issue might be with the use of the default JAAS authenticator. In which case, does using a custom authenticator fix the issue?

One red-light flashing is by using problemStatisticTypeBEST_SOLUTION_CHANGED/problemStatisticType http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/index.html#d0e7101 I 'd like to automate detection of it: https://issues.jboss.org/browse/PLANNER-120 If you see this, you probably have a score trap: https://issues.jboss.org/secure/attachment/12359971/badBecauseScoreTrap.png Then run the solver again, but terminate it in the middle of that first flat line and write the solution. Then examine that solution for score traps. Just pushed a new image and some docs explaining score traps better, as several users might have encountered it: https://github.com/droolsjbpm/drools-planner/commit/e9034f4ac60e7a4bd65f7223c5a3dd47e0d7b903 Thanks, Michiel - http://www.codessentials.com - Your essential software, for free!

Re: [rules-users] solution equals and hashcode are never called.

It is easily to see the solution on sight and if I feed it with the prepared solution (in a custom solver phase) it "finds" the optimal solution right away. If you can easily see the solution on sight, you should also be able to easily see which move it should do to reach that optimal solution. What does logging with level TRACE print? Can you find the move it should do in that log? What score does the log say that move has? I'm trying everything and try to review everything I have written. It is during that review that I noticed that the equals and hashcode methods of my solution implementation class are never called. Obviously the solutionEquals and solutionHashCode methods of my planning entity are never called either. solutionEquals/HashCode is only called with solutionTabuSize, which is worthless when scaling out (unlike entityTabuSize). A solution's equals/hashCode is never called. entityTabuSize should be calling the planning entity's equals/hashcode, at least in Planner 5.5-. For Planner 6.0 I am looking into stop relying on the entity's equals/hashcode, in case users have overwritten the default java.lang.Object behavior in a way that's incompatible for Planner. What should I conclude out of that? Is this a crucial issue? If so, what should I check/change? I am running Drools Planner 5.5.0.Final on java 1.7.0 on a Windows 7 64bit machine.

[rules-users] multi-tier decision application in drools server
Hi Everyone, I am trying to use drools 5.5.0 to provide approval/denial for a case. The best way to represent our business logic is through a workflow where the user-inserted facts get processed in a particular step, and the RHS of the rules in that step insert new facts for the next step in the flow, until, at the end, a decision fact is generated. Looking at the Drools Expert tutorial, this is very similar to the driver license application, except that mine has a jbpm flow. As such, I have been using a stateless session to get my rules to work. Until recently, I have been working on this problem as a local drools expert solution, referencing the rules engine and the rules package directly. However, the final step was going to be to move this solution to drools server so that the business logic could be accessed through a RESTful interface. I assumed that the main functionality available in the drools rules engine would remain in drools server. However, when I saw the following post, I became concerned that perhaps the functionality I took for granted in Drools Expert does not exist in Drools Server. The post was recent and has not gotten a response, but if the response is indeed that stateless sessions do not work with rule flows in drools server, I was wondering if anyone had a suggestion for how I would tackle my workflow problem. Is there another way in drools server (other than salience) to get different sets of rules to execute in a particular order and come up with an answer at the end of the work flow? http://drools.46999.n3.nabble.com/Ruleflow-not-working-with-stateless-session-in-drools-server-5-5-0-Final-td4021624.html Best, Yuri PS.

[rules-users] hot deployment behavior
Would someone be so kind to describe exactly what happens when we hot deploy a rule change to a stateful session. It looks like the old version of the rule is deleted, in turn forcing a retraction of any RHS that was logically inserted (all our inserts are logical) as a consequence of this rule (and any cascading effects) that has no other LHS to support its existence. Then the new rule is inserted, the agenda is rebuilt based on the current working memory contents, and the rule is automatically fired (in our case recreating everything it just deleted) Do I have this right? Is there a way to change the behavior to be less invasive? This rebuild can take minutes, and I am not running at high volume yet. For example what if the updated rule logically has no impact on existing working memory contents, let's say it's a maintenance change for future facts or new conditions? If the operation did not delete and rebuild everything, rather if it determined the impact of the change, and only replaced retracted/deleted what is affected by the logic change, would this be faster? Bottom line it would be highly desirable for this to be minimally invasive. thanks [cid:image001.gif@01CDF7F0.4B5CB130] Bill Guinn | Sr. Vice President, and CTO SUMMUS Software, Inc. 3179 Skyway Court, Fremont, CA 94539 510.780.3895 office | 916.715.6433 mobile @summussoftware twitter william.gu...@summussoftware.commailto:k...@summussoftware.com [cid:image002.png@01CDF7F0.4B5CB130] [cid:image003.jpg@01CDF7F0.4B5CB130] http://www.summussoftware.com/pdfs/EMA_NGITM-Q4-2012_Radar_Summus-Profile.pdf NOTICE TO RECIPIENT: THIS E-MAIL (INCLUDING ANY ATTACHMENTS) IS MEANT FOR ONLY THE INTENDED RECIPIENT OF THE TRANSMISSION, MAY CONTAIN CONFIDENTIAL INFORMATION, AND IS PROTECTED BY LAW.

Re: [rules-users] hot deployment behavior
You have it right. If any rule is modified, it's effective removed and added. Removal of a rule, remove's all it's matches, activations and logical inserts. There is no way to preserve this information for a rule that modified. It would be very hard to determine what information is or is not safe to preserve. If the rule is a very minor change then add a new rule instead, it will re-use all the available sharing (matched information). It can build up a second set of justifiers for the logical insertions. Then you can remove the old role.

[rules-users] Implementing Refraction with Drools
I believe we can inject in Refraction capabilities into Drools Rule Engine
using a simple Agenda Filter. I have tested this with test cases against
JRules and Drools and get similar results. Without the Refraction Agenda
Filter it loops infinitely as expected.
Please try it out and tell me what you think. I believe refraction is a much
needed feature of a forward chaining rule engine for commercial purposes.
Any feedback is deeply appreciated.
Here is what the code looks like
-Agenda Filter---
package test;
import java.util.ArrayList;
import java.util.List;
import org.drools.runtime.rule.Activation;
import org.drools.runtime.rule.AgendaFilter;
/**

public class RefractionAgendaFilter implements AgendaFilter {
private List encounteredActivations = new ArrayList();
@Override
public boolean accept(Activation act)
{
//Check for a Refraction
if (encounteredActivations.contains(act))
{
//Remove from encountered activations for future firing
encounteredActivations.remove(act);
//return false so the rule is not selected as part of the refraction
return false;
}
//Otherwise add the rule to check for potential refractions in the future
encounteredActivations.add(act);
//select the rule to be part of the agenda
return true;
