Hi Ricardo,
Yes you can store the Drools working memory / knowledge session into a
persistence storage to restore the previous state later.
The same mechanisms are used for Processes. You will see that
jbpm-persistence-jpa contains a dependency to the drools-persistence-jpa

You are using @propertyReactive. Have you read the documentation in
the Drools Introduction and General User Guide? It's too long to
repeat here...
You better not use this feature unless you are fully confident that it
meets your
If your program terminates without any new session, dispose() need
not be called.
Getting different results for different runs with the same program+data
is strange unless you use generated random test data or rules based on
time in some way.
That's all I can say given the info provided.

I only have one session during every run. So using dispose is general
correct in my case.

Hi,
As I see it , this is a big problem.
I was looking at drools about 10 months ago (5.3.0 Final) and debug worked
just fine ... ... so similar to earlier comment of Bruno here.
Today I downloaded drools 5.5.0 Final eclipse Juno and debug is broken
...
Can we expect a patch? I can't see
I suspect the version of drools and guvnor you are using are not identical.
Use of RuleAgent is most certainly not helping. Did you look at the
/droolsjbpm/guvnor/guvnor-examples demonstration using KnowledgeAgent?

Hi Kevin,
did you try the workaround I suggested; setting rule dialect to mvel? That

There is a JIRA issue for the problem with debugging Java rules here:

Hi,
I have finally gained a tiny bit of control (and maybe even some competency) in
using the DROOLs language operators 'no-loop' and 'lock-on-active' as a basis
for controlling rule set firing behavior in response to Fact mutation events
(during consequence processing).

Instead of using drl files I want to implement the rules in Java, but I

solution as fast as possible.

You cannot use an interfact (List) to instantiate an object, which
is happening due to the collect.
