Changing Task Workflow version or task status

Oct 2, 2012 at 1:02 PM

Hi,

I actually have a problem where I have a WF designed by SPD. I created tasks in it using collect data from user activity.I currently faced a problem where a task shows an error on editing. "This task is currently locked by a running workflow and can't be edited". I searched the internet and found that I should check task[SPBuiltInFieldId.WorkflowVersion] as if isn't equal to 1 , then I can change it to 1 to solve the problem so I downloaded SP Manager and navigated to the task list and to the specific item but I can't see a field/property called "workflow version" so kindly advise If I can change it using SP Manager or not and how to access it or kindly inform me if I can change the status of the task to be completed.

Thanks in advance.
