Hello,
I need some help to understand how to enforce dependency rules with Drools.
Suppose you have two objects - A and B - and two business rules that say:
if A is selected, unselect B and if B is selected, unselect A.
How can I be sure that Drools unselects B when user selects A and
Yeah, its in the classpath.. and to be doubly sure just before the code I do
a
Message s=new Message();
and that works.. so jvm can find the Message object.
I have created https://jira.jboss.org/jira/browse/JBRULES-2348
I would love to know if any workarounds are possible, this has ground my
Ok, i have looked at the drools source and I see the following:
TypeDeclaration lastType = null;
try {
// Add the type declarations to the RuleBase
if ( newPkg.getTypeDeclarations() != null ) {
// add type declarations

Hi,
We are running Guvnor on two machines, out of which one is used for
developing and testing rules, say test environment, and another is
used for providing rules for production application. Our test
environment typically contains more than one package and each in turn
contains multiple

I implemented the following listener for my bean and I am calling .update()
directly on the StatefulKnowledgeSession.
QUESTION 1: Is there a better way? The old API supported
.insert(fact,boolean). The new one does not. I am not finding any
documentation that explains the new API (version
Hi Geoffrey,
I'll check that out today for you and let you know what I find out
with my case. I'm using the following solver dependency:
dependency
groupIdorg.drools.solver/groupId
artifactIddrools-solver-core/artifactId
version5.1.0.M1/version
I 'm using Drools flow 5.1m1 and have created a simple Timer test flow.
It has a simple Action node after the timer that Prints out Hello.
I have set the timer delay to 5000 and the Timer Period to 2000. What I
expect to happen is I get Hello printed after 5 seconds, then followed
by Hello
Here is a twist.
If I call update($fact) explicitly in the rule, the rule is NOT called twice.
Can someone point me to the code used by update($fact)? Maybe I can figure
out what I did wrong to cause the rule to fire incorrectly a second time.

The Update command appears to be processed in
org.drools.process.commands.UpdateCommand. It's doing the update the same way
I am.
Why does this code work when Drools uses it, and it doesn't work for me?
package org.drools.process.command;
import org.drools.reteoo.ReteooWorkingMemory;
I think I've solved this. You have to fire the property change event *AFTER*
you change the underlying property. As long as session.update() is called
*AFTER* the value has changed, things seem to work correctly.
Does this sound like a reasonable solution? I think I saw in the documentation
Hi Geoffrey,
My bad; when I migrated to the new Score implementation I failed to
update my code to properly clone scores in my cloneSolution()
implementation. Thanks for letting me know where to look!
best wishes,
