by GPatel＠tsys.com
Is there a way to set the rule-flow group of a rule via the guvnor UI?
Thanks

Unable to validate package configuration (eg, DSLs, models) for [package name]
by John Peterson
Hi,
We recently upgraded from Drools/Guvnor 5.0.1 to 5.1.1 (early December).
We had an existing package we had developed in 5.0.1 that we had not
done much with since the upgrade. This morning, we tried to open one of
the rules in that package and we get the following messages:
<<Picture (Device Independent Bitmap)>>
Unable to validate package configuration (eg, DSLs, models) for [package
name]. Suggestion completions may not operate correctly for graphical
editors for this package.
<<Picture (Device Independent Bitmap)>>
Unable to get content assistance for this rule.
<<Picture (Device Independent Bitmap)>>
Unable to get content assistance for this rule.
I've tried to re-upload the 3 jar files (I saw this post as a possible
solution: http://comments.gmane.org/gmane.comp.java.drools.user/23407),
but I get "Unable to upload the file". New packages seem to be okay
(e.g. packages created since the upgrade). Does anyone have any
thoughts on what's going on here?
Thanks.

Upload an existing .drl for the Guvnor dynamically
by Vandewilly
Is there any api available that allows me to load an existing file drl for
the Guvnor repository. In my case, I can not upload through the web
interface, only in a dynamic way through a java class.

StatefulKnowledgeSession.startProcess not thread-safe ?
by OptimusPrime
Hello,
I wrote a micro benchmark in order to test the performance of Drools Flow
5.1.0 in single and multi-threaded environments.
And I noticed that, when 2 threads call startProcess() at the same time
(Intel Core 2 Duo CPU), the returned process instance IDs are the same.
I checked the code and it seems there is no locking mechanism in the
org.drools.process.instance.impl.DefaultProcessInstanceManager class for the
id creation.
Is this a bug or am I missing something ?
Thanks

Exception while loading session from JPA store
by jawa
Hi,
I've got a drools application running with EJB3 and JBoss 5.1. It works fine
but most of the times it throws exception while trying to load drools
session from JPA. My flow has got user tasks so it stops at places and get
stored in db using JPA. Then I try to load it by providing the session id
which does exist in database but it fails to load with following exception:

Deploying Guvnor 5.1 on Glassfish v3
by alim
Hello,
I downloaded Guvnor, web based BRMS (WAR) Version 5.1 and tried to deploy it
on Glassfish v3.
Unfortunately without success.
To be more specific:
I put "drools-5.1.1-guvnor.war" into
{glassfish_home}\domains\{configuration}\autodeploy and started Glassfish
within Eclipse 3.5, using Java 6.
I get following error:
Exception while invoking class org.glassfish.ejb.startup.EjbDeployer load

I've already tried the hints I found on Google such as changing the web.xml

Hope someone can help me.
Thanks a lot!
