I can add new records to the business object (and underlying table) but when I try to update one of the existing records I get the following error.  The problem table only was one column as the primary key and it is not an identity column (auto generated).  Looking at the partial BO class, it appears that the correct column is being used as the primary key.

BusinessLayerException

  An error occurred while saving an the data to the server.

DataLayerSavingException

  Cannot create UPDATE command because the updating DataTable does not contain columns for all PrimaryKeyFields.
