[jBPM Development] - DeploymentAdaptor: duplicated process deployment since commi
by SNy
Hey,
I've found a problem with the JBoss deployment code in jBPM4.
It has been introduced in commit 4753 which added forms support via freemarker .ftl template files.
A change was made in the DeploymentAdaptor's deploy() method to add all resources from the given zip input stream (instead of just the specified process descriptor .jpdl.xml given in the DeploymentMetaData).

This was apparently done to add the .ftl templates to the deployment but has the (IMHO unintended) consequence of also adding ALL processes from the archive.
In combination with the way the .bar is deployed in JBoss, this results in multiple deployments (DeploymentAdaptor called n times for n process descriptors in the .bar) each including all the processes (ie: a .bar with 4 .jpdl.xml files will result in 4 deployments each including all 4 processes).
Also, I found the deployer to not really consider the timestamp of the .bar. When starting/stopping the server, it will undeploy the processes (which suspends them as indicated in jira issue JBPM-2242) but instead of reactivating them it will redeploy them which then results in another n deployments.
I know, two issues in one post, but they are kind of related.
Regards,
Marko

[jBPM Development] - couldn't get task instances list for actor pooledTaskInstanc
by andrzejurban
Hello,
I have a problem regarding use of a pooledTaskInstanceList on my agenda. I'm using jBPM 3.2.2.GA and JBoss 4.2.2.GA server.
I create a new process instance using an annotated method:
@End
@CreateProcess(definition = "KNFExport", processKey = "#{exportId}")
public String saveExport() {
Then I access my agenda :

On my agenda I can see a newly created task on a group task list.
When I use the 'assign to me' button,
instead of a rendered page I get an error:
"couldn't get task instances list for actor 'admin'"

When I restart the JBoss server with cleaning all the data,tmp,work folders, then it works fine. I see a task on my personal list(the task was transferred from one list to another despite the exception).
But if I click the 'Assing to me' button, I get the same exception as before.
The same situation is when I have more tasks on both lists and when transfering a task from group task list to my task list.
Can anyone tell me what could be the cause?
I've searched the forum but couldn't find anything useful.
I can provide any additional info to help you solve this.
Regards,
Andrzej Urban
