Pooled groups and assignments

ale_carraro — Mon, 02 Jul 2007 15:08:00 GMT

Hi, I had a problem with pooled groups, but (fortunately) I found a trick that solves. I ask what I understood badly:if I have this definition everything works fine (note that corrector and publisher are defined intentionally the same way): <swimlane name="commdirection"> <assignment

I also noted that if you return to a task that has a swimlane defined as a pooledactor for the second time, the 'error' applies, too.

ie.
A is a group,
1,2 are tasks
1 is a task with A as a swimlane.

if I do the following transitions: 0->1->2->1 at the end nobody in A see the task n.1

if I do the following: 0->1,take ownership->2->1 at the end the task is a personal (not pooled) and owned by the one that owned after step 1

I'm going to think it is a bug…

I've confirmed this is a bug - it'll be fixed in 2.1.

However, I haven't been able to reproduce your first case - I'm guessing it's caused by the same issue. Can you send your full process definition please?

I tried 2.1 and both are solved. Very good job!

Now a (I hope) simple question: is there a way to 'force' a user to take ownership before going on the next step?
When the task is on the pool, I have both the buttons <Next step> and Get Ownership. The problem is that if I click on Next Step the task does not show in the My completed tasks dashboard….

thanks for your marvelous work

Unfortunately not - that's a feature to be done in a future release.

To workaround the "My Completed Tasks" issue (yes, it's probably bug), you can extend your process definition to add the following event to your pooled task:

            <event type="task-end">
               <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                  <script>
                     <expression>
                        if (taskInstance.actorId == null)
                           taskInstance.actorId = person.properties.userName;
                     </expression>
                  </script>
               </action>
            </event>

Hopefully, that helps.

thank you! It works, but now I have to make another question: I tried to put those 2 lines in the transition script, but I got this error: "taskInstance" not defined.

Since what I know about the JBoss workflow is from the alfresco's wiki, I wonder where can I find documentation on the subject, for example a list of the variable defined in "event" tag

Can anybody address me on this? thanks

http://docs.jboss.com/jbpm/v3/userguide/

If you've attached your event to a task-node, that script should work. Can you paste your process definition xml.

is there a way to 'force' a user to take ownership before going on the next step?

BTW, a fix has gone into 2.1 Enterprise for this, it will make its way to HEAD.
