>I have a view on a free table, buffering is set to 3, Optomistic row. The TableRevert doesn't work. Any ideas what could cause this?

Did the record pointer move in any way? If so, it was implicitly committed and TableRevert() won't work.

How did you verify the value of the record? If you used Browse, this internally moves the reocord pointer while building the browse, committing the change. Use Browse NoWait before your test so its pre-built during testing.
