StartersProcess - task assigned to null, null

[jstachera]

I deployed the StartersProcess from jBPM Getting Started and after the state 'Receive Return' I got a message:

New tasks have been assigned to: null, null.

(the next step in the process is fork node).

My question is why I don't have information about next users which were assigned to the task (bert, ernie) ?

I have looked into the code and I found that next assigned user is retrieved by: taskAssignLog.getActorId()

if (assignmentLogs.size() > 1) {
 String msg = "New tasks have been assigned to: ";
 Iterator iter = assignmentLogs.iterator();
 while (iter.hasNext()) {
 TaskAssignLog taskAssignLog = (TaskAssignLog) iter.next();
 msg += taskAssignLog.getActorId();
 if (iter.hasNext())
 msg += ", ";
 }

unfortunatelly that method returns null, but if I use

getTaskNewActorId()

instead, it would be ok:

so another question is what is the difference between following methods:

taskAssignLog.getActorId()
taskAssignLog.getTaskNewActorId()
taskAssignLog.getTaskOldActorId()

??

Check the jbpm_id_user table to make sure the users are in it. I believe you will see that message if the users do not exist in the table.

All the users are in the JBPM_ID_USER table.

I see you have:

 <swimlane name="Shipping">
 <assignment expression="user(sors)"></assignment>
 </swimlane>

Is the user "sors" in the user dropdown? Does it work correctly if you use "grover" instead?
