<p>I am using Oracle BPEL Process manager and have a task assigned to a group of users. 
I try to mark it approved using Java class oracle.bpel.services.workflow.task.ITaskService.updateTaskOutcome(). This works if the task is assigned to an individual user, but if the task is assigned to a group of users, I get an error message about the task not being acquired. </p>

<p>If I acquire the task using oracle.bpel.services.workflow.task.ITaskService.acquireTask(), I get an error message when trying to mark it approved: "The task has been acquired by some other user".</p>

<p>Can anybody point to sample code that changes status of an Oracle BPEL task <em>assigned to a group</em> programmatically?</p>

use
```
updateTaskOutcomes()
```
method instead of
```
updateTaskOutcome()
```
when it is assigned to multiple users
