Hi,
We are using JBPM5.4 with the JBPM5.4 final full installer.
We have been going through this issue:
1. We created an application to complete some human tasks in one function, so lets say it completes 20 human tasks (20 different process instances) by calling calling Task Client's completeTask(..) 20 times.
(We use HornetQ Human Task Service)
2. All the 20 task will always get completed (double checked the Task status in Database changed to "Completed")
3. The weird thing is, out of those 20 tasks from 20 different process instances that got completed, usually we got 2 or 3 process instance that does not resume
My Question are:
1. Anyone have clue about what may be the cause?
2. In the event where Human Task Service tell the JBPM Console Server that there is a task completed, and JBPM Console Server fails to get that event, how do we replay this? is it possible? When JBPM says HornetQ Human Task Service, does it mean that HornetQ Messaging used to send message between JBPM Console Server and Human Task Service? if so, can we replay failed messages?
Any Help is appreciated.
Thank you
Regards,
Thomas Setiabudi

[jBPM] - create a new boundary event

Hi guys,
I want to implement a timeout event for one of my processes. I saw an example where there's a boundaryEvent -> Script -> End flow integrated in the main flow .bpmn (it's not connected to any other process), and basically it sets a timer cycle attached to some reference, which expires after a while (in my specific case, I want to force abortion of the task if it's not completed after 6 hours). Here's the bit of code of the example I downloaded:
<boundaryEvent id="_4" name="TimerEvent" attachedToRef="_7" >
<timerEventDefinition>
<timeCycle xsi:type="tFormalExpression">500ms</timeCycle>
</timerEventDefinition>
</boundaryEvent>
When trying to implement this in my actual project, I noticed there was no editor in the eclipse .bpmn interface for setting up boundary event, only intermediateCatchEvent. When I changed the .bpmn file code, it doesn't save my custom boundary event, it just overwrites it. So my question is, how can I set a boundary event in jbpm5.4 using Eclipse?
Cheers

Is it hibernate issue or issue with BMT?
Initially I have an empty process db. When I tried deploying jBPM console but I got similar error while persisting the SessionInfo instances. Then using an application I created those instances, even process instance is also started by using an external application, the link to which is provided in jBPM console. The external application uses CMT.
Please help

[jBPM] - drools-scorecards : jaxb-generated bean property accessor names don't match what is expected in 'client' sources

hi,
i'm trying to build a 'stable' release of drools + jbpm (drools 5.5.0.Final + jbpm 5.4.0.Final) and there seems to be an issue regarding drools-scorecards : generated bean property accessors' names don't match the expected (by 'client' sources) ones.
For instance in org.dmg.pmml.pmml_4_1.descr.Scorecard there is a property 'useReasonCodes' of type Boolean with a generated accessor name 'getUseReasonCodes()', while org.drools.scorecards.drl.AbstractDRLEmitter expects 'isUseReasonCodes()'.
This results in a compilation failure.
AFAIK accessor names can be customised in bindings.xml configuration file but i'm trying to build the same stable release that is available through jbpm full installer package and don't want to make any unnecessary amendments to the code.
To obtain the stable release of drools + jbpm i have used the procedure described in {thread:id=221196} :
-- git clone mailto:git@github.com git@github.com:droolsjbpm/droolsjbpm-build-bootstrap -b 5.5.x (to clone the bootstrap repository and set active branch to '5.5.x')
-- droolsjbpm-build-bootstrap/script/git-clone-others.sh 5.5.x 5.4.x (to clone the dependent repositories and set active branches to '5.5.x' for drools and '5.4.x' for jbpm)
-- droolsjbpm-build-bootstrap/script/git-checkout-all.sh 5.5.0.Final 5.4.0.Final to checkout tagged versions 5.5.0.Final (drools with dependencies) and 5.4.0.Final (jbpm)
Afterwards i tried running droolsjbpm-build-bootstrap/script/mvn-all.sh clean install -DskipTests to build all modules - but ended up with described compilation errors in drools-scorecards.
I attached the source files metioned above (generated Scorecard and 'client' AbstractDRLEmitter).
Thanks in advance for any assistance.
