I don't think you can get hold of workItem directly from Task ---- the only reference Task has the workItemId. May be you can serialize the workItem and set to the content of the Task( I don't like it) - and then retrieve it later --- else I guess you have to get hold of WorkItemInfo and then workItem..
Also creation of knowledgesession is not process/time consuming so I don't see any harm in there ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Todd Pagni Sent: Tuesday, December 08, 2009 11:57 AM To: Rules Users List Subject: Re: [rules-users] Human Task Work Item 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.

I see the Task.getTaskData(), but I don't see any easy way to get the work item as I need the work item inparameters from the mina client side. Thanks, Todd
