Question
by Heng hh
Hi all
I would like to ask how drools run . I found that they can run in two
different drl file. What is salience for ?.
rule " Teting 571"
salience 4200
when
root:AdjudicationDTO(type=="PRIORAPPROVAL_LINE",t:type);
pa:PriorApproval();
pal:PriorApprovalLine($pb:productBenefit);
cct:PriorApprovalTreatment(id!=null,$c:clinical);
then
System.out.println( "571= PASS ");
if(
root.getAppliedUcr($pb.getBenefit(),pa.getProposedDateOfTreatment(),pal.getClinicalUcrs(),$c)!=null&&
root.getAppliedUcr($pb.getBenefit(),pa.getProposedDateOfTreatment(),pal.getClinicalUcrs(),$c).getUcrType()!=null&&

root.getAppliedUcr($pb.getBenefit(),pa.getProposedDateOfTreatment(),pal.getClinicalUcrs(),$c).getMinChargeLimit()!=null&&

||
root.getAppliedUcr($pb.getBenefit(),pa.getProposedDateOfTreatment(),pal.getClinicalUcrs(),$c).getMinChargeLimit()!=null&&
root.getAppliedUcr($pb.getBenefit(),pa.getProposedDateOfTreatment(),pal.getClinicalUcrs(),$c).getMinChargeLimit().compareTo(pal.getAllocatedAmount())<0
)
){
registerPALineStepStr(pal,571+cct.getId().toString(),
"571 Clinical treatment UCR validation",

whern to remove persistent stateful drools session
by Stephan.Koops＠We4IT.com
Hi,
I use drools with JPA peristence. It also persists the sessions. If I want
to load them back, I got an exception. So I create a new session every
time a need one. Is this a bad (or not good) strategy?
When can I remove the persisted session from the database? Directly after
closing it? Or can I disable the persistence of session, so only the other
things are persisted?
Thanks in advance.
Mit freundlichen Grüssen/Best regards
i. A.

Ruleflow "stalling" in stateless session - no events, workitems, etc
by drdaveg
I apologize if this is covered elsewhere, but I am not sure of the keywords
to search that would not return 1000 posts.
I have ruleflow running from a rule that starts it in a
StatelessKnowledgeSession. I am doing this to avoid inferencing, which is
present in the stateful version of this application. I am starting the
ruleflow from a rule with no ruleflow-group.
The ruleflow seems to run until it executes a rule in the first rule
RuleflowGroup node. The subsequent node, included for debugging, just
displays a message to the console and is never reached. There are no
parameters to the ruleflow, no events in the ruleflow, no workitems (as this
is simply a ruleflow) so I am wondering how processing has stalled before a
node with no conditions for entry.

drools flow - why after reloading some process previously completed workItems gets executed once again?
by gs76pl
hi,
i've a simple drools flow process with one workItem (its execute method
simply prints some text) and one human task. I'm using
drools-persistence-jpa to save my process status and load it when
process/server crashes.
What i've noticed is that:
1. after starting process my processinfo table gets updated with a new
process status (P1)
2. my workItem (W1) runs correctly and prints a text
3. a human task gets created
----- when i stop my server at this point and restart my server executing
below steps
1. load the session using
JPAKnowledgeService.loadStatefulKnowledgeSession(myPreviousSessionId,....)
2. start the process
At this point previously completed workItem (W1) gets executed once again
and the same human task gets created !!
I thought that perhaps the issue is with my transactionManager not
committing steps but since i'm using local transaction (commit happens after
any process step) its very unlikely.
Is it a bug that the same workItem gets executed or is it intentional and
it's up to the developer to check somewhere else whether specific step has
been already finished or not..?

[Drools Flow] Stop a timer event
by JAMAL Moundir (EXT)
Hello,
I'm using Drools Flow 5, I have N Message events waiting for a signal to be started, I want to launch a Timer in the beginning of my WorkFlow, if one of the event is received, then I want to stop the Timer and execute my workflow, else I want to execute another branch of my workflow.
For example :
1- Start
- Launch the Timer of 30s
- Wait for a Message (external event)
2- Case 1 : External event received before 30s
- Execute SubProcess 1 and stop the Timer
Case 2 : Timer reached 30s
- Execute SubProecss 2 and ignore the external event
How can I stop the Timer when the case 1 is verified ? Can I do such as thing with Drools Flow ?
In my current implementation even when the case 1 is verified, after the 30s the subProcess2 is also executed !
Did someone implement such us thing
Thanks,
Regards

> I've executed several times the SampleAlarmRules scenario and found that
> the problem in that scenario is the existence of a JoinNode (Node 18) which
> feeds two nodes, a JoinNode (Node 20) and an AccumlateNode (Node 25, the one
> in which NPE occurs). I've seen that the child tuples of a join node are
> interconnected via pointers and that those connections must be updated every
> time a parent tuple of the join node is modified, via reAddLeft and
> reAddRight tuple methods. When a JoinNode feeds two or more nodes, the child
> tuples are interconnected in a ordered way that mixes tuples with different
> sinks.
>
> In the SampleAlarmRules scenario, when JoinNode18 is right modified, the
> CompositeLeftTupleSinkAdapter processes several child tuples, but only the
> last one is returned and reAddLeft'ed, hence breaking the child tuple
> relations which it seems necessary to keep rete coherence. After this right
> modify, the next left modify fails because a child tuple related to one node
> of the composite sink is used to check the next operation to do in another
> sink node different from the first one. This leads to a chain of incorrect
> assertions which ends in the AccumulateNode NPE.
>
> I've rewriten my rules in order to JoinNode18 feeds only AccumulateNode25
> thus avoiding the NPE and returning to my user role. However I am not sure
> if any CompositeSink starting at a JoinNode will have this or other problems
> when being left or right modified. I hope this information helps to solve
> this problem.

KnowledgeAgent Issue
by Steven Williams
Hi all,
I am trying to use a Knowledge Agent in 5.1.1 with a change set with a few
different packages and resource types in it, and I am running into a problem
where it is not adding all the packages. Looking at the code I can see that
KnowledegeAgentImpl.createPackageFromResource has the following code when it
loads a resource:
if (kbuilder.getKnowledgePackages().iterator().hasNext()) {
return (KnowledgePackageImp)
kbuilder.getKnowledgePackages().iterator().next();
}
and KnowledgeBuilderImpl.getKnowledgePackages does the following:
Package[] pkgs = pkgBuilder.getPackages();
List<KnowledgePackage> list = new ArrayList<KnowledgePackage>( pkgs.length
);
and PackageBuilder.getPackages does the following:
for ( PackageRegistry pkgRegistry : this.pkgRegistryMap.values() ) {
Package pkg = pkgRegistry.getPackage();
// add package to array
}
pkgRegistryMap is implemented as a HashMap however so the order the packages
are returned in is not guaranteed. I seem to be hitting this problem.
This is a hard one to create a unit test for so I wanted to check that my
analysis is correct before raising a bug. Perhaps using a LinkedHashMap or
similar would fix it?
thanks
