Any clue..look like its a permission issue....

Migrateduser

Hi

I am not much sure,but check weather user initiating the WF has permission to change/modify file extended attributes(meta-data of a file).
You can check it as follows--
1.Identify the role of user.
2.Go to Administration Pannel
3.Then Select Mange Roles Under Teamsite Admin-->Configuration-->Roles and Permissions.
4. Edit the required Role(that's you user role)
5.Under The Heading
Files, Forms and Folders
Essential file, form and folder manipulation operations.
6.Their should be check on the permission property
Modify File Extended Attributes *

7. If its uncheck,then check it and try .

Hopefully it would work in your case.
As this permission property sets the metadata previlege for user.
