Potential Bug in Guvnor with usage of "from collection" and "Any of the following are true"
by Sean Su
I found that the statement generated from "from collection" is not correct
when it is used in combination with "Any of the following are true"
feature. There is ">" being generated in frond of the statement which is
causing the compilation error.
Here is the code being generated from the guided editor:
java.util.Collection( size >= 1 ) from collect ( ProcedureEvent( elements
contains 4658 ))
( >java.util.Collection( size == 1 ) from collect ( ProcedureEvent(
elements contains 7788 , eval( contiguousDays.createNewWithPaddedTime(1,
DateTimeUnit.DAY).intersectsButNotAdjacent($diagnosticEvent.contiguousDays)
)))
or >java.util.Collection( size >= 2 ) from collect ( DrugEvent(
elements contains 4146 ))
)The code above was from the item 8 and 9 in the attached screen. As shown,
the collection statement is correct when there is no "any of the following
are true" involved.
This seems to be a bug in Guvnor.
Please let me know if this needs to be reported.

Guvnor error when compiling imported process
by pritispin
guvnor-error.png
<http://drools.46999.n3.nabble.com/file/n4025853/guvnor-error.png>
Hi Guvnor Team,
I am having a process definition in Eclipse and it runs fine. But we want to
use Guvnor as the repository so I imported the process definition from
Eclipse to Guvnor but I get following error when trying the build the
package.
Can someonep lease give me some clues based on the attachement. I have no
logs as it does not write anything to serbver.log
I'm runnnig latest jbpm-full installer 5.5 which starts the jBoss AS 7.0
server. The process definiton has tns:defaultPackage and I also included
some of the jars (business related classes that are used in the script task)
in the drools-guvnor.war->lib and repackage it and restarted the server but
I still keep getting the same error.
I don't know is it not finding the business classes/jars or is this error
related to something else?
How can I see more logs related to guvnor in jBoss.
Thanks,
Priti

What is the defect tracking process for Drools Community Edition
by adarsh.chaini＠hsbcib.com
All,
We are using drools as our rule engine in one of our mission critical
application which is distributed in nature .
Recently we have found a very bad memory leak with in the drools that does
not clean the some of the listeners after the execution of the
session(stateless in our case).
This caused our distributed JVM's to grow quite rapidly in and we had to
fix this by manually removing those listener which we never added as users
of the API.
What is the process to track this and find if this is already known and
fixed in a later version.
We are using the following components and dependencies where ${drools.ver}
is <drools.ver>5.3.1.Final</drools.ver>

Compatability between Eclipse jBPM5 5.5 Editor and Designer 2.4?
by kawest173713
I had implemented a process in Designer 2.4 (thru Guvnor), using the Workflow
pattern "Arbitrary Cycle" that is provided out of the box with the designer.
Basically just created a new process within Designer, then placed the
Arbitrary Cycle pattern into the process, and saved it - without making any
changes to it. I was able import it into Eclipse (Kepler) and bring it up
from within Eclipse with no issues.
Because the out of the box Arbitrary Cycle pattern had validation errors, I
went back into Designer to fix all the validation errors and modify the
tasks, which included:
- made all the tasks script tasks
- Changed all of the paths out of the XOR gateways to have a "50%"
probability
- added a start and end event
- added a flow out of task E to the end event
- added a flow out of G to the end event
- created a png of the process
I then selected the validate process button, and everything validated fine.
Switching back to Eclipse, I imported the process using the File -> New ->
Resources From Guvnor.
When I then tried to bring the process up in Eclipse, I got the following
popup error:
An exception occurred while reading the Ruleflow XML: this type of node
cannot have more than one incoming connection!
In the Eclipse log for the worspace, it had the following exception:
java.lang.IllegalArgumentException: This type of node cannot have more than
one incoming connection!

at
com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(Unknown
Source)
...
Given this, it seems to me that the designer is creating processes that the
Eclipse editor is unable to parse/render. Is this expected behavior - i.e.
is the designer a superset of the Eclipse editor capabilities?
If so, what capabilities are in Designer that aren't supported in the
Eclipse editor - if such a list exists? I just don't want to spend much time
implementing in the Designer if I never know what will/won't import to
Eclipse.
Thanks,
Keith

DSL statement in Guvnor too long
by Sean Su
Does anyone know if we can force the DSL statement in Guvnor to be
displayed with multiple lines when it is too long to fit into one screen. I
believe the default behavior is that it keeps expanding with the horizontal
scroll bar, instead of wrapping to fit the screen.
Thanks

Expected Transaction Rollback Behavior of Drools 6
by Alexander Herwix
Hey guys,
I have a question regarding the expected transaction rollback behavior of drools 6 in an JTA-Environment. It looks like I have successfully configured drools within my app, however when I create a KieSession within a Transaction and roll it back, there is still some data persisted to the DB.
e.g. session info (the last record should be rolled back)
