Hi Jeffrey,
We did some investigation on our development system regarding this issue. When you update a column and return to a saved view, it may appear that the data has been lost because the column is missing but we would be very surprised if the data was actually gone in the underlying table. What may be happening in this case is that the column was renamed correctly and the data is retained but the existing view still references the old column name which is not displayed. To check for this, look in customize view for your table. You may then re-add the new column.

If you would like us to look into this issue further, please let us know.

Greg
