Hello,
Recently i started playing out with Drools Guvnor GUI and created couple of
rules based on DecisionTable
GUI Editor and also ruleflows in eclipse.
Then integrated Drools with Java Custom Web Application and tried out
executing rules on front end by changing rules on the drools guvnor at
Hi All
When I dispose the Knowledge Agent still using knowledge base i am able to
get the session and fire the rules.
I there any way to dispose the Knowledge base.
Who will take care of dispose of the Knowledge base.
Can u please suggest me.

In response to a couple if your questions:-
1) Guvnor uses an optimistic lock at the asset (e.g. decision table) level.
We do not provide for merging as you describe.
3) Guvnor uses Apache Jackrabbit for persistence. Jackrabbit can be
configured to use a database however the schema Jackrabbit
Hello,
about your point #1, you can use status of rules and therefor only build in
production if a rule is in special case, but is is tricky and there is no
merge facility and possibility in Guvnor. The only way is to do it from
whithin eclipse with the the guvnor plugin over webdav.

Hello,
Are you using a Rule Template or Decision Table? Your post states template
(decision table) but these are two different things entirely.
That aside, it does sound like a bug - you should either not be able to
define invalid column names in Guvnor or we should provide a means to
protect
There must be something in WAS's log indicating a problem of some sort.
Have you tried with a completely clean repository, i.e. delete the
repository.xml and repository folder entirely?
Since the problem only occurs in your DEV environment (I assume a DEV
server somewhere, not your local IDE DEV

Hi folks,
I'm happy that I recently discovered both the Eclipse debugging views for
Drools (working memory, agenda) and the FIT for rules framework. Since our
development project itself can't be tested as Drools-Application I'd like to
use FIT for acceptance-tests and debugging. Might be a smooth
Thanks for your inputs..
#1. it means if multiple users update same record (in this case decision
table ) then other one changes will be overwritten, as it shouldn't be i
believe.
#3. is it way to import this repository into eclipse to see data by using
some plugin ?

#1 - Two users, (1) and (2), open the same asset. User (1) saves OK. User
(2) will be prevented from saving as their view of the underlying asset is
out of date.
This is how the optimistic lock pattern works. It is ideal for low
con-currency usage patterns, which is how we envisage Guvnor
Hi Nicolas,
Thanks for your valuable inputs.
#2, did you observered how much memory was consumed while building such huge
rules ?
do we need to consider memory consumption in this case?

If you have a StatelessKnowledgeSession (or StatefulKnowledgeSession)
object, you'd call its method setGlobal () to assign an object to a
global variable.
If you don't have the session object, you can acquire it in some other
way, e.g., in consequence (RHS) code. You'd use the predefined
variable
Hi everybody,
might be that I found the solution myself.
Is it possible that FIT uses an abstraction-layer (like e.g for persistence
JPA-Annotations instead of original Hibernate annotations), which prevents
Eclipse from applying breakpoint functionality?
FIT imports:

In 5.4.0.CR1, to not have the exception, I put
ValueRange.excludeUninitializedPlanningEntity on false (That also works if
I dont use this attribute, its default value is false). The solver seems
doing the right moves.

Hi,
I have nested classes in the domain model and I imported these nested
classes in order to use them in the guided editor. Things are ok except
when one of the rule required a custom java function, then I would get an
error at 'build' package time (the error is 'not able to resolve
Hi,
This was a bug, but has been fixed for 5.4.0.Final.
The only workaround is to move the enumerations to their own class, rather
than nest in another Class.

I don't know your data model, but I believe, what you may be looking for is;

$pt: Patient ( )
$test : LabTest( ) from $pt.labTests
not (exists (LabTest (testId == $test.testId)))

No you can't ... or I really don't know how ..
You can duplicate a ruleflow group in a ruleflow (if your rule is only
dependant of others rules in the same group), but if a rule is a subpart of
multiple groups ... well ... I think you can't avoid to write your own agenda

Hi,
I downloaded the Guvnor 5.4.0 CR1 and problem is still there (I am assuming
the fix is in this CR release too?). I would like to send this image to
show one of class in the domain model that contains nested classes.
TcItem contains Dataset contains NamedReferences
I do this.
I use a custom function to perform my inserts like this: (I also have a
property called rule in my data facts, that I store the rule name into so I can
trace the logic tree that set the fact values). This is also based on the
assumption that your facts you are created are being
You can simplify the last condition to:
not LabTest(testId == $test.testId)
I think it's faster, too.

Thanks for the feedback
Yeah.. my rules deal with data transformation. We convert vendor feed data to
internal data for making trade decisions. So we have large data sets that need
to be evaluated. So instead of inserting all data into working memory from
our lookup tables in our DB, I
I will have to play with performance testing on these conditions.
My understanding was that there is not real performance difference, because
every fact insert get evaluated at insert time for rules that reference the

Can you create a JIRA (https://issues.jboss.org/browse/GUVNOR) and attach a

I can take a look to check it's working as you require with (what will
become) 5.4.0.Final.
Otherwise, it'll be a bug and need

Tell me if I understand well :
- you have a set of lookup rules that are independant of initial data in
the WM
- you have another set of lookup rules that depends of data currently in
the WM, that should trigger in the middle of data processing. In this second
group, some business rules can

What's the best way to encode a fact that's needed in the RHS but is not
important in the LHS?
Consider a contrived example of computing total household income for single or
married persons. I can think of two ways to encode this rule, but I don't like
either of them:
Style 1: one rule for
Sorry, I wasn't clear... In the example, it's the spouse that's the optional
fact. I want the rule to fire whether or not a spouse exists, but the RHS
computes the income differently if a spouse exists or not. If a spouse is
added/removed, I want the rule to re-fire and the income should be
I was using template to build the decision table type of rule editor. I
have switched to the decision table since then.
However since the template design allows me to achieve the decision table
look and feel, it would be great to allow us to define the display name of
the column as well.
Yes,
In fact, you question is : What's the best way to define something that's

You said not important, but you want the income to be updated (I guess for
other rules' LHS) ... so it was not clear.
