Hi,
I'm using UIPAB v 2.0 in a Windows application. Following the UIP
documentation I'm trying to "nest" two tasks. As I need to pass data between
those two tasks, I;m using the OnStartTask method. This is what the
documentation say about nesting tasks, using that method:
"When the Add New Shipping Address process is ready to return, retrieve the
TaskId for the Purchase Product process, which is stored in the current
task's state, and invoke the OnStartTask method, passing the name of the
navigator, the new address, and the original TaskId. If the task state for
the specified task is found, the current view for that task is displayed."

The problem is that the OnStartTask method requires an Itask implementation
as its third argument and not plainly the TaskId. Should I implement the
ITask just for the sake of resuming a suspended task?

Thanks,
Gwenda

Hi Gwenda,

Sorry for letting you wait for so long.

Based on my understanding, you want to pass the TaskID to the OnStartTask
method through the third parameter of this method with ITask type. You want
to know if we have to implement this interface ourselves.

Yes, we should implement a ITask ourselves to provide the ability, this is
document in the following "Note":

Note The task and taskId parameters are required only when you start a
previously suspended task. These parameters are relevant only if you have
implemented the ITask interface to provide the ability to suspend and
restart tasks. For more information about implementing the ITask interface,
see "Implementing the ITask Interface," in Appendix A, "Extending the UIP
Application Block."

Just as the document stated, you should refer to "Implementing the ITask
Interface," in Appendix A, "Extending the UIP Application Block." to get a
guide about how to implement ITask.

Hope this helps.
