Hi all,
Anyone knows how to reassign a task to group when the task is in states Ready, Reserved or InProgress?
In our scenario this can happen when a user has a reserved task but the business administrator at some point can change the assignment to a group.
I tried with the following methods:
* *delegate:* produces the following error: Error java.lang.RuntimeException: Command OperationRequest faild due to org.jbpm.task.Group cannot be cast to org.jbpm.task.User. Please contact task server administrator.
* *nominate and forward*: produces: unexpected end of subtree [select new org.jbpm.task.query.TaskSummary( t.id, t.taskData.processInstanceId, name.text, subject.text, description.text, t.taskData.status, t.priority, t.taskData.skipable, actualOwner, createdBy, t.taskData.createdOn, t.taskData.activationTime, t.taskData.expirationTime, t.taskData.processId, t.taskData.processSessionId) from org.jbpm.task.Task t left join t.taskData.createdBy as createdBy left join t.taskData.actualOwner as actualOwner left join t.subjects as subject left join t.descriptions as description left join t.names as name, org.jbpm.task.OrganizationalEntity potentialOwners where t.archived = 0 and ( potentialOwners.id = :userId or potentialOwners.id in () ) and potentialOwners in elements ( t.peopleAssignments.potentialOwners ) and ( name.language = :language or t.names.size = 0 ) and ( subject.language = :language or t.subjects.size = 0 ) and ( description.language = :language or t.descriptions.size = 0 ) and t.taskData.status in ('Created', 'Ready', 'Reserved', 'InProgress', 'Suspended') and t.taskData.expirationTime is null]
Do you have some advices?
P.S. I'm using JBPM 5.4.0-SNAPSHOT.

[jBPM] - Form with multi-select yields single String instead of Collection
by Martin Müller

"Form with multi-select yields single String instead of Collection"

--------------------------------------------------------------
Hey,
when a user starts a process instance in the jBPM Console I'd like to display a form with a select input allowing multiple selection.
I've got the form displayed properly with the multi-select box. However, when submitting the form the corresponding process variable only gets filled with a String containing the first selected value. Any other selected value is discarded, and I would have expected some Collection type instead of a String.
The form is a basic HTML form inside the <process_id>.ftl file:
<form action="complete" method="POST" enctype="multipart/form-data">
<select name="list" multiple="multiple">
<option value="value1">Option 1</option>
<option value="value2">Option 2</option>
<option value="value3">Option 3</option>
</select>
</form>
If I select "Option 2" and "Option 3" in this example and then start the process the list variable is set to a String "value2".
How do I make it return a Collection with all selected values instead?
Thanks in advance,
Martin

[Beginner's Corner] - SSO with Kerberos in JBoss-6.0.0.Final

--------------------------------------------------------------
Hi,
I'm trying to enable kerberos SSO on my JBoss-6.0.0.-Final.
To this purpose, I have created the following:
1. a simple webapplication in jsf
2. linux server has a keytab file and is part of ms active directory
3. added an application policy (see below, named "SPNEGO") that uses Kerberos Module
4. the jsf contains a jboss specific deplyoment descriptor that refers to the security domain defined at 3.
5. in the jsf's web.xml, I've set the auth-method and the realm-name
I stil can access the JSF from a PC without kerberos ticket.
Where am I doing wrong?
web.xml

[jBPM] - Could not load org.jbpm.task.event.TaskCompletedEvent

To whom it may concern,
I'm confused to pinpoint where the cause occured. I have started my web app successfully but when I'm about to invoke my method which creates a task in the jbpm,
this exception appears:
Sep 7, 2012 6:07:25 PM org.apache.catalina.loader.WebappClassLoader loadClass
INFO: Illegal access: this web application instance has been stopped already. Could not load org.jbpm.task.event.TaskCompletedEvent. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

[Beginner's Corner] - Session invalidation not happening at the right time

"Session invalidation not happening at the right time"
To view the discussion, visit: https://community.jboss.org/message/758914#758914
--------------------------------------------------------------
Hi,
Am using Jboss AS 5.1.0 GA. I have JSF 1.2 servlet running on it.
I have a Customised session listener which extends PortalSessionListener (am running Liferay 6.0)
In web.xml, I have configured session-timeout to be 3 minutes. When I hit my JSF servlet, and dont do any thing for 3 mins, then my customised session listener gets invoked and sessionDestroyed(HttpSessionEvent httpSessionEvent) is called.
Before 3rd minute if I carry out some activity on my servlet then the session gets extended. Then I wont do anything. This time if I watch the logs, my customised session listener is getting called at around 2nd minute instead of 3rd minute and its invalidating the session by calling sessionDestroyed(HttpSessionEvent httpSessionEvent).
*My first question is why is that session invalidation not happening at the right time* in the scenario described above?
Also, I have configured a session-timeout in web.xml of my Servlet. Am using httpServletRequest.isRequestedSessionIdValid() method to check if the session is valid or not. In the above scenario
when session got invalidated at around 2nd minute, this time after the session invalidation log got printed, if I click on any page on my Servlet it still finds that session is not invalidated yet.
But, its finding the session got invalidated only exactly after 3rd minute.
*My second question is why is this difference between session-timeout configured in Jboss AS web.xml and the one configured in Servlet's web.xml?*
Regards,
Vikas
