I have a custom MVC app that presents worklist to a user and allows the user to action their tasks. The requirements I'm trying to fullfil is to provide the ability for (1) a flow originator to cancel a workflow and (2) an admin group to edit or cancel a request/flow. I was thinking about creating an "Admin" task right off of START which would create the task for admin folks, and the MVC app could provide the admin functionality from there. However, that task may never get completed because it may be uneccessary for that flow. I have a similar situation where a group of people may be given a "survey" task where I don't really care if they action the task or not. I do however want the flow to continue through another critical path - to completion. Is there a way to create an activity/task that doesn't NEED to be completed for the flow to ever complete? With me?
