This task is currently locked by a running workflow and cannot be edited in visual studio workflow.

Question

Hi All,

I am working on visual Studio 2010 Workflow. I am using the workflow to create the task.

I can create the first task. When I am going to change the task i.e. Approve or Reject, I am getting the following error :

Server Error in '/' Application.
--------------------------------------------------------------------------------

This task is currently locked by a running workflow and cannot be edited.

Some Points I found:

1. I can log the Workflow History which is after "OnTaskCreated" Activity.
2. I can change the task after removing the "OnTaskCreated" Activity.
3. when I am using "OnTaskCreated" Activity the Error is occurred in "OnTaskChanged" Activity. After Removing the  "OnTaskCreated" Activity the "OnTaskChanged" Activity is working fine.
4. I need "OnTaskCreated" Activity to apply/Update the Security/Permission on task and List Item.

Please help...
