Unlock Task Due Date to be retrieved via a SmartObject
In the Task step of a workflow one can set the Due Date and then the Worklist can show the value. This Due Date property of a Task should also be available for developers via a SmartObject. This would enable users to view that relevant information about a task on their SmartForm.
In K2 Blackpearl 4.7, developers could use Expected Duration to inform end users when a task was expected to be completed by displaing the information on a SmartForm. As described in https://help.k2.com/kb002726, the old Expected Duration is now Due Date for K2 Five/K2 Cloud but the new prperty is currently not available for developers.

Ross also requested the addition of Worklist SmartObject properties "Due Date" and "Proc Inst Id".
