Re: [rules-users] Drools 6.0.0 activation-group + salience bug or feature?
Thanks for answer,
well I thought that the activation-group and salience applies only on
the rules with the same LHS, I mean exact match by equality. But there
it cancels different ones. Nevermind.
The game doesn't exist (yet). It is for my diploma thesis coordinated by
Red Hat. I have to implement game logic of civilization-like game.
As for my project, I started blog a while ago, but lately I'm busy
writing my diploma thesis, so I haven't updated it for a while. Here it
is: http://civilization-mmo.blogspot.com/ . Also you can visit my github
account where again there are some projects concerning the game, but
current version is to be added in short time. Hopefully by 26 may it
shall be updated.

That’s what an activation-group does. The first rule (with the highest
salience) fires, the others are cancelled.
Out of interest, what’s the game? Something online we can look at? I have an
interest in games development for Drools, and have been slowly adding
examples. Space invaders was my latest one:

Hi,
I came across in my view strange behaviour of rules defined with

priority of exclusively fired rules Democracy City Tiles Production

Their definitions:
rule Democracy City Tiles Production
dialect mvel
ruleflow-group manageProductions
activation-group cityProduction
salience 5
when
PlayerDTO($owner:id, government==democracy)
$city:CityDTO(

,$sumFood : sum($foodProd)
,$sumResources : sum($resourcesProd)
,$sumTrade :
sum(($tradeProd1)?$tradeProd:($tradeProd+1))
)
UpdateCityProduction(cityId==$cityId)
then
modify($city){

}
end
and
rule Basic City Tiles Production

ruleflow-group manageProductions
activation-group cityProduction

$city:CityDTO(

)
UpdateCityProduction(cityId==$cityId)
then
modify($city){
setFoodProduction($sumFood)
,setResourcesProduction($sumResources)
,setTradeProduction($sumTrade)
}
end
But problem occurs when two CityDTO objects are in the session. I would
like to fire one rule for each CityDTO, but the activation-group cancels
all the activations after first is fired. So only one activation in
place of two fires. Here is the log:

Re: [rules-users] KieScanner not working
Hi Alex, sorry but I am not fully understanding your use case. You wrote that “drools_jar” is a kjar (i.e. is a project containing a kmodule.xml file) but project_jar” isn't. Nevertheless in your code snippet you're creating a KieContainer against project_jar” that actually isn't a kproject. Of course this couldn't work so I am pretty sure I am misunderstanding the description of your use case. Can you please better clarify what is a kjar and what isn't (i.e. which project contains the kmodule.xml file). It would be even better if you could open a ticket on our Jira and attach your samples projects there, so we can be sure that I am reproducing exactly your use case.

Re: [rules-users] KieScanner not working
Alex, sorry but what you're saying is just NOT possible and it doesn't depend on kie-ci. If your project_jar doesn't contain a kmodule.xml file, you CANNOT do something like: ReleaseId releaseId = ks.newReleaseId( com.study, project_jar, 0.0.1-SNAPSHOT ); KieContainer kContainer = ks.newKieContainer( releaseId ); If you try to you should get a RuntimeException saying: java.lang.RuntimeException: Cannot find KieModule: com.study:project_jar:0.0.1-SNAPSHOT I suggest you to open a ticket on our Jira and upload your sample projects there so I could reproduce your actual issue.

The rule is using

So, if a MyObject with val==0 is inserted, then after 5 seconds no MyObject
with val==1 is found the rule will fire.
This works in Drools 5.5.0
In 6.0.1 the rule doesn't fire.
Please help. I want to use drools 6 but cannot with this problem.

Re: [rules-users] KieScanner not working
However I confirm that it is not possible to create a KieContainer out of a project that doesn't contain a kmodule.xml file. Sorry, Mario, I didn't make myself clear. My project_jar is indeed a kjar. I just not looking to have any rules in project_jar dynamically updated. What I'm focusing on is drools_jar, for which I want the rules to get updated. project_jar depends on drools_jar: dependency groupIdcom.study/groupId artifactIddrools_jar/artifactId version0.0.1-SNAPSHOT/version /dependency Initial version of rules runs just fine when project_jar is deployed. However, KieScanner is not picking up any updates in drools_jar.

[rules-users] How to implement immovable planning entities for vehicle routing problem?
I am implementing a vehiclerouting like solution with OptaPlanner 6.0.1.Final. According to the documentation for continuous planning, the way to 'lock' parts of the solution is by declaring a movableEntitySelectionFilter on the planning entity: Section 14.3.1. Immovable planning entities. However, this does not work well with chained entities where parts of the solution is calculated, like in the vehiclerouting example. For example, let's assume the following chains, where [Customer A] and [Customer C] are immovable: [Vehicle 1] - *[Customer A]* - [Customer B] [Vehicle 2] - *[Customer C]* - [Customer D] Even if we filter immovable entities, a move to set the variable [Vehicle 2] as previous standstill to [Customer B] can be selected with the following result that changes the immovable entity [Customer C]: [Vehicle 1] - *[Customer A]* [Vehicle 2] - [Customer B] - *[Customer C]* - [Customer D] A workaround is to filter moves with immovable entities as well as moves with immovable variables (variables are also entities). However, this can only work when immovable entities are placed at the beginning of chines before any movable entities. Is there a better way to implement immovable planning entities for vehicle routing problem? -- View this message in context: http://drools.46999.n3.nabble.com/How-to-implement-immovable-planning-entities-for-vehicle-routing-problem-tp4029467.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools 6.0.1 Negative Patterns in Stream Mode not working
Can you try 6.1 beta2? And if there is still a bug, please open a jira:
http://mvnrepository.com/artifact/org.drools/drools-core/6.1.0.Beta2
Ideally please submit a self contained unit test, as a pull request. As
explained here:
