I don't see what is the solution in @khanh's workaround, except to request a feature...
Also, thanks for the documentation and samples.
More or less, I am aware of the structure of the K2 API described in that file that you attached, but I still don't see how to set up EventInstance's expected duration in K2 Five.
EventInstance has a property ExpectedDuration, and i would like to set it from K2 Workflow Designer, so I could use it.
Thanks for the answer. As i said in the initial post, i set up Due Date, but WorklistItem in K2 API is not reflecting that value in any of the properties. Maybe, the more correct question is how to retrieve Due Date using K2 API? Any suggestion on this? The answer would be the solution for this ticket.
