Lock-on-active and FROM
by FrankVhh
Hello all
It has been a while since I posted on this forum as I was assigned to other
tasks for a while. Anyway, I have not forgotten about the source of
knowledge that is this user forum!
We are using Drools 5.3.0. In the expert manual, section 5.8.3.6.2, the odd
behavior of lock-on-active and FROM is highlighted.
However, we cannot reproduce this reported behaviour. See annex for .java
file and drl file.
In the documentation, it is sated that only one rule should fire, in the
example and as we run it, we can get both rule activations to execute. Could
anyone cast the bright light of explanation on this phenomenon?
It would also be helpful if someone could provide us with some additional
information about why you should expect only one rule to fire.
Thank you very much for your time and highly appreciated explanations!

Drools 6 Fusion Example
by rjr201
Hi,
Does anyone know of a simple (complete) working example of a Drools Fusion
project using Drools 6?
My kModule.xml file so far looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<kmodule
xmlns="http://jboss.org/kie/6.0.0/kmodule">
<kbase name="KBase1" default="false" eventProcessingMode="stream"
equalsBehavior="equality" declarativeAgenda="enabled"
packages="org.domain.pkg2, org.domain.pkg3" includes="KBase1">
<ksession name="KSession1" type="stateful" default="false"
clockType="realtime">
</ksession>
</kbase>
</kmodule>
However, I think I need to define an entryPoint in the kmodule.xml.. but
can't find an example of how to do this.
If anyone can point me to an example it would be greatly appreciated.
Cheers,
Rich

Guvnor on weblogic
by konsouv
Hello guys,
A little help please.
I want to deploy guvnor on weblogic version 12.1.2.0.0. I downloaded
guvnor-distribution-wars-5.6.1-20140618.143413-14-weblogic-12c
from
http://snapshots.jboss.org/maven2/org/drools/guvnor-distribution-wars/5.6...
When I deploy it I get the following stack trace.
<Error> <Console> <Souvatzop-HP> <myserver> <[ACTIVE] ExecuteThread: '1' for
queue: 'weblogic.kernel.Default (self-tuning)'> <weblogic> <> <>

After some research I think that the problem is that the beans.xml file in
WEB-INF folder is not read during deployment. It is not considered at all.
Is there any advice for me that could help me complete the deployment?
Thank you in advance.

Size and contains methods of List in Drools
by Sumit Dhaniya
Is it possible write conditions on the basis of size of a list using guided
editors (either guided decision table or guided rule) and to check if any
element is present in the list?
For eg.
User {
List of badges;
}
now I want to apply condition on number of badges and if a specific badge is
in user's list of badges.
Also can I compare to objects. For eg. condition on count of badges of two
users?
I'm using KIE Drools Workbench
Here's how source code should look like :-
import com.demo.dto.User;
import com.demo.dto.Badge;
rule "Compare two variables"
when
$user: User(name == "Sam")
$badge: Badge() memberOf $user.getBadges()
then
$user.setImpact($user.getImpact + $user.getBadges().size())

unsubscribed from the rules-users mailing list
by Wolfgang Laun
Friends,
this is to let you know that I have done as the subject says.
I'd like to thank all that have contributed for their continuing
efforts. As for myself: I think that this is a good moment to retire,
with my rapidly diminishing capability of understanding what's going
on in Guvnor, Optaplanner and other newfangled extensions. Hitting the
"delete" button on some incoming email has been the one thing I've
managed to do faithfully, and frequently.
Thanks again, and it's been *very* nice meeting you.

Optaplanner - Linking time windows of vendors and the depot
by alainb
Dear All,
I'm trying to model multiple time windows of the same vendor by multiplying
the vendors with different time windows and demand. This seems to work.
However, I can do the same with the depot but it doesn't represent what I
need.
I'm using salomon tw example, but i need certain demand to be there in one
time window of the depot, and other demand at the other time window of the
depot. In other words, I would need to link demand at a time window of a
vendor to a specific time window of the depot.
Does anyone know if there is any possibility to do this? Or can somebody
suggest me some further steps. I would be really thankful.
Thank you all in advance,
Kind Regards,
Alain

SelectionFilter<ChangeMove> question
by dBijkoo
i have a class ChangeMoveFilter which implements
SelectionFilter<ChangeMoveSelector> to sort out moves that break hard
constraints.
In the config it looks like this
<constructionHeuristic>
<queuedEntityPlacer>
<entitySelector id="placerEntitySelector">
<cacheType>PHASE</cacheType>
</entitySelector>
<changeMoveSelector>
*<filterClass>solver.move.ChangeMoveFilter</filterClass>*
<entitySelector mimicSelectorRef="placerEntitySelector"/>
<valueSelector>
<cacheType>PHASE</cacheType>
</valueSelector>
</changeMoveSelector>
</queuedEntityPlacer>
</constructionHeuristic>
However I am getting the impression that the overridden accept function is
called before anything changed in the entity. Because the (only)
planningvariable of the entity is still null, which would never be able to
happen in my understanding.
Am i missing something or is the filter move called before anything changes
in the given entity?
