<p class=MsoNormal><span style='color:#1F497D'>Thanks for the info. I was
hoping there was a way to get the work item via mina. We have a client
application that is communicating with the TaskServer via mina and it would be
nice if you could easily get a work item that is associated with a task
instead of creating a separate knowledgesession. <o:p></o:p></span></p>

with a human task?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I see the Task.getTaskData(), but I don’t see any easy way
