Without changing the rules: you might also use a WorkingMemoryEventListener
to collect the inserted new Fact objects.
A StatefulKnowledgeSession provides the method getObjects(), with or without
a filter, so you might consider using that.

Hi All,
Is there a way in which we can use a collection in the condition of a rule
(to be used in contains, memberof) , which can be managed by a Guvnor User
containing big list of elements (may be 10,000).
Having this in a Database is an option but considering the maintenance of
the list where
Option 1 is to just use a stateful session - from my understanding there is
pretty much no difference in terms of overhead.
The other option is to insert a 'ResultsAccumulator' object containing a
resultList. I
If you don't need to reason over your new Facts than rather than inserting them

You need a way to differentiate between policy's that have been updated and
that haven't been updated.
If you have control of your model then you could add an extra field, either as
a flag or containing the new value - if this field is null you know you need to
update it.
If you can't change
HI Deepak,
You never did answer my question:
Can you create new rules when configured to use Oracle? If so your
configuration, I'd assume, to be correct. AFAIK the repository folder is
only relevant if you're using JCR's file-system storage - if configured to
use a database I doubt it has much
There is no provision in Guvnor to build lists of facts to be used by rules.
Please feel free to raise a JIRA requesting such an enhancement for
consideration though.

HI,
I'd just like to clarify, for others who come across this thread, that it's
not a Guvnor issue, but a Drools Expert (that does the compilation).
Anyway, here's two solutions for you:-
(1) Add the typesafe annotation to your DRL
declare Test
@typesafe( false )
end
rule prueba2

The correct form for this kind of constraint in 5.1.1 is
UNB.size 0
(5.2.0 is more lenient.)

I think normally setGlobal variables are only used when you want to be able
to call back out to the java code again. (I'm not an expert by any stretch
so please take that with a grain of salt.) So you might be able to just

I'm going to assume the List is really

This is how to do it - although it's not recommended to use globals in rule
conditions. (For one thing: the list must be complete before you call
fireAllRules().)
global List list

Perhaps a more fully constructed question might be advantageous?

I think that you have to access the property id of the matched System object
and use this for constructing the new System facts:
id $system.getId()

Ok I will describe it again:
We want to administrate some objects in guvnor. Every object has one id, one
name and one description. We have round about 100 objects.
One use case is, that all objects (id, name and description) should be
displayed in a drop down box in our web frontend.

Guvnor provides for the means to author rules, not consume them.
There's no capabilities to insert your objects (other than when writing test
scenarios for your rules). This would be the realm of KnowledgeSessions and
*your* application.

Quoting from the original post:
Our customer want that we use drools to administrate some objects. The

Thanks Swindel.
The eligibilityScore is updated on 3 different rules by decrementing the
value if the condition is satisfied. Finally the eligibilityScore value is
used in the downstream. Is there any pattern available for these types of
use cases.

Add a name into the policyUpdated type - each type of rule which should operate
separately only references policyUpdates of that given name so you stop those
from retriggering while allowing the others to trigger.

There are many ways of doing unit testing in DROOLS - with or without
Eclipse. My last client is using JUnits with the Eclipse JUnit plug-in
where the tests examine the firing of individual rules and the values set on
domain objects. One advantage of this approach is that you can run any

Your issue looks like a persistence issue, not a DROOLS issue. If you do
more metering and experimentation people may be able to solve this for you.
You may want to check posts from about a year ago; there were MANY people
asking about JPA workflow persistence.

Thank you Michael for your quick answer :) I certainly hope there will be
somewhere some answer to the other points as well.
You can use a predicate within a pattern by selecting Predicate as the
Condition Column type. These compile to inline evals. It is not however
