Getting an error message when trying to view an approval workflow

  Asked By: Kiel    Date: Sep 25    Category: MOSS    Views: 2405

I am getting an error message that states,

System.Xml.XmlException: 'ows_TaskStatus' is a duplicate attribute name.

This is for a MOSS installation.

This is what happens when a user starts the "collect feedback" workflow for a
document.

The tasks gets assigned, the user that the task was assigned to gets an e-mail,
and milliseconds later gets the same task e-mail again causing a conflict in
Outlook. If the user chooses to keep one item and then complete the task as
usual, everything seems okay, until trying to view the comments on the server.
An error message comes up saying that "There was an error while loading the
form." And the user is given the option to try again, or close the message.
Trying again only brings up the same error message dialog. The user also gets
the option to "Show error details." What is posted below are the results of
that. Hopefully someone can figure out what happened.


'ows_TaskStatus' is a duplicate attribute name. Line 35, position 277.
