[rules-users] Hibernate session and 'from'

2011-04-07 Thread Gareth Evans

Hello,

I am using Hibernate lazy loading in the facts I am inserting and am
noticing some odd behaviour when I use 'from'.

Here is a simplified example of my problem. In the first rule I just
want to populate the working memory with the Child objects, it uses
Hibernate lazy loading fine and inserts the facts, however in the
second rule I get an exception when accessing the GrandGrandChild
saying that the object does not have a session. If I add some debug
code to the first rule to access the GrandGrandChild I get the same
error.

This is using session-per-request and the Parent object was inserted
in the current session.

rule "get children - broken"
   when
   $parent : Parent( )
   $child : Child( ) from $parent.children
   then
   insert($child);
end

rule "do stuff"
   when
   $child : Child( )
   then
   GrandChild grandChild = $child.getGrandChild();
   # it blows up on the next line
   GrandGrandChild grandGrandChild =
grandChild.getGrandGrandChild();
end

If I replace the first rule with the following everything works as
expected and I can match on Child objects and access whatever I wish,
so I know there should be a session available in the "do stuff" rule.

rule "get children - working"
   when
   $parent : Parent( )
   then
   for(Child child : $parent.getChildren()) {
   insert(child);
   }
end

I am able to use the "working" version in my code however the "broken"
version seems like the more correct way to do this in Drools. I'd like
to understand what is going on in case it is my fault or an issue I
need to be aware of. Could it be something to do with the from keyword
or the "cast" to Child( )? Is there some "magic" done in Drools which
could remove/invalidate the Hibernate proxy?

Thanks,
Gareth

@FrankVhh

Entry-points are used with CEP; you'll find details in the Fusion
documetation.

With kind regards,

Re: [rules-users] Combination of conditions doesn't work

2011-04-07 Thread FrankVhh

Hi Sariman,

The trick with "from entry-point", is quite unfamiliar to me. There might be
some problem with that, but I cannot tell by looking at it.

However, there are a few problems with the rules that you have printed out
for us.

1) The way I understand it, they do not do what they should be doing. You
said you do NOT want an action when all sensors evaluate to true. In your
case, you are evaluateing whether all sensors are false. This is pretty
useless if you already have a rule which evaluates the existence of at least
1 "true" sensor. The way I would put this is like this:

rule "Myrule"
when
#conditions
sensorEvent1: SensorEvent(booleanValue == true)
exists( SensorEvent(booleanValue == false) )
then 
#actions
end

2) There are some errors in your rule. No idea whether this is a copy/paste
or a read/type, so I will just point them out.
- ";" is usually not needed in a LHS, I am not familiar with the from
entry-point syntax, but I assume it wouldn't be needed
- There is a ")" in excess in one of your conditions

3) I don't think it makes sense to put your rules as you did in the second
example. Even if you are trying to examine whether those three sensors are
false.

On a personal note: what does from entry-point do? I must have overlooked it
in the documentation.

Regards,
Frank

Re: [rules-users] difference between jBPM and drools?

2011-04-07 Thread Esteban Aliverti

Drools Flow was separated from drools trunk and re-branded (with additional
modifications) to jBPM5. So, drools code 2 will not contain Drools Flow. If
you want to use Flow, then just go to jBPM5.

Re: [rules-users] Help with Accumulate function

2011-04-07 Thread Dwipin C

Thanks Wolfgang. 

The issue here is that the accumulation has to happen at a higher level in
the object hierarchy, "Position" in this case. However, this is no direct
link between Position and PostitionPnlAttributionAmount ( which is being
accumulated). How do I tackle such a scenario?

$attibAmtType will be just one for the condition given, but there could be 
multiple $posPnlAmt within a Position. 

Thanks,
Dwipin

Well, this explains it - you'll have to find the selecting combination
of $posPnlAmt and $attibAmtType in a unique way, assuming there is
just one such combination.

One way to exclude siblings for a fact X is to use a constraint such
as "there is no other X with an identifying, comparable id < than the
only one I want".

  X( $id: id, $interesting: interesting )
  not X( id < $id )

So to clarify, does Drools 5.2 contain Drools Flow any longer, or has this 
been superceded by jBPM 5? If I wish to submit feature requests, bugs 
etc., is there a separate issue tracker for jBPM 5?

Thanks,

Hi, 

I don't find much about the difference between jBPM and drools flow, only 
that jBPM is the official one (
http://www.jboss.org/drools/drools-flow#Drools_Flow_and_jBPM, first 
paragraph of the section) and rethinked. I'm interested for the practical 
site. 

Can anybody tell me about the advantages or disadvantages? What are the 
main points to decide which one to use? 
Maybe I missed a blog entry or something like that, but I don't find more. 
A pointer or something else would be nice. 

Thanks in advance.

$posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) 
- 2 ( with all above facts)
$posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn,

All of them together without the accumulate fires it 6 times.

Repeated firing may be due to there being more than one scope for 
accumulating
the sum, as selected by the patterns leading up to the accumulate.

If you take only the patterns preceding the accumulate - how often does 
this fire and for which elements? You need a single combination of 
$posPnlAm and $attibAmtType.

eval ($totalPnlAttibAmt > 1000)

When I do it this way, the rule gets executed 6 times, basically for every
fact that evaluated to true. How do I restrict this? The rule should be
executed only if the final eval results in true.

Thanks for any help,
