Csla.DataPortalException: DataPortal.Fetch failed (DataPortal.Fetch failed (An item with the same key has already been added.))
Possible causes / fixes:
* Check Employee Custom Properties to see if there are two properties with the same name.
* This is the result of someone leaving a note at the same time someone else did, and Terry will need to remove the note from the database.
* Two tracking levels with the same name
* If the error message is generated during export, check export IDs for duplicates.
