Hi,
Are you suggesting to maintain a list of B values in A?
Like A { list<B>();}
// inside my A
And then to populate the list and iterate through that list??
Is that not too much extra data storing?
Thanks
M

If B has a getA() method, you could do something like this:
rule "XX"
when
$list: List(size > 0) from collect B(a.name = "x")
then
someGlobalList.addAll($list);
end
best,

Hi,
Thanks. Sorry for not being clear.
I have the following:
A = new A(); A1 = new A()
B b1 = new B(A)
B b2 = new B(A)
B b3 = new B(A1)
Each of the B above have a parameter "name"
I am setting the name in one of my rules which works properly.
I want to create an output list which:
Checks that all B objects pointing to a single A object (eg. A1 or A in
this case) have same name. If they don't I don't want to have them on my
output list.
I tried using forAll for the rule but that checks forALL B's in genral
having same A object which is not what I want.
Could you give me a starter / hint to create the rule.
I even thought that I could maybe populate a list for each A object:
When $a : A()
b : B(a : $a , name == "x")
Then
Modify($a){
setAList(b) // adding all b's to a list contained in a
};
But that does not help me achieve the second part as I cant traverse
through a list inside rules.
Any idea??
Please help.
Thanks

You were right the first time - I am sharing the environment between
multiple sessions. That is easy for me to fix.
Can I share the EntityManagerFactory, or should I create one for each
session?
Thanks,
Rob

oh.. sorry.. you are creating a new env per each session.. but the problem
is related with that..
I will review that and let you know.

yes the problem is the environment.. I saw that problem in the past..
you need to create a separate environment object per each session.

The idea of the tests is to ensure that our implementation is thread-safe.
Each thread in the test creates its own Drools session and executes its own
workflow (which contains actions and work items that involve user
interaction that is simulated by the unit test).
This scenario tests the real-world case of our server handling sessions
from multiple users. There should NOT be cross-talk between these sessions.
Without persistence, everything works as expected. With persistence enabled,
two sessions running in parallel are enough to fail 100% of the time.
Each thread creates a session like this:
session =
JPAKnowledgeService.newStatefulKnowledgeSession(getKnowledgeBase(), null,
getEnvironment());
The calls to getEnvironment() return the same value each time it is called
called. Is this right?
The environment is created like this:
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
Any idea where I messed up?
Thanks,

What kind of thread safe tests are you doing?
if multiple threads modify the status of the process, only one of them will
commit the new status, and the other ones will rollback the transaction
because of a bad state.
Is that what you are looking for?

We are using version 5.1.0.M1. We have long-running processes (flows). They
are long-running because we have work item nodes that involve the user of
our application to do something. We are in the development cycle of our
product and everything is going well. I am trying to configure persistence
and running into some issues.
I am to the point where our basic unit tests appear to be running fine with
persistence enabled both in the container (tomcat6) and in our unit testing
environment (ServletUnit).
We have unit tests that run the same test in multiple threads in parallel
(the idea is to try to expose thread safety issues), and these tests always
fail. At the end of this message, I have pasted a few of the different stack
traces I have seen.
I expect that I have done something silly in the configuration, and I could
use some help in finding it. I am not sure if the problem is my
configuration of JPA, Hibernate, the DataSource, or if it is an interaction
between what Drools is expecting and the details of my configuration.
Thanks,

If you can do it in Java, you can do it in a rule.
Asking questions in this very general way will only (if at all) give
you very general answers.

New subject: deleting records using rules
No. If B class has a reference to A, then *$list: List(size >0) from collect
B(a.name = "x") *will collect all B fact having a.name == "x" into a
new
List
You could read the documentation about *from collect *for further
information.

Hi,
Are you suggesting to maintain a list of B values in A?
Like A { list<B>();}
// inside my A
And then to populate the list and iterate through that list??
Is that not too much extra data storing?
Thanks
M

If B has a getA() method, you could do something like this:
rule "XX"
when
$list: List(size > 0) from collect B(a.name = "x")
then
someGlobalList.addAll($list);
end
