Imagine you have updatable local view with optimistic buffering (5). When you want to save changes to involved table, all you would to do is to issue TABLEUPDATE(.T.) on the view. But...
The table musn't be buffered. If not, you have to issue second TABLEUPDATE on the updated table.

The question:
How to force the table to be not buffered in DE?

Answer 1 (wrong):
Set the form's BufferMode to '0-None'
Set DE.table's BufferModeOverride to '1-Use Form Setting'

Answer 2 (working):
Ignore form's buffering setting - set '0-None' directly to DE.table.

Do you know any other solutions?
