We have some workflows that are generating tasks for the users. We would like them to be able to completed from a centralized form in addition to answer them from emails or the Workflow task list.
We've tried a number of options thus far including trying to complete the task from the workflow through powershell or C# Service. While we've successfully got the task to say completed, other tasks are not marked as completed.
(The scenario is that multiple user can complete a given task. In the normal course if one of the users completes the task, the rest of the tasks are completed by the system.)
