Dear Dmitry

I have the following problem with MemTable:
I use a TmemTableEh Component with Property CachedUpdate=True, connected to a DatasetDriver Component with DataProvider a TQuery Component. In my program the code is as below:

MemTable.open;
MemTable.Edit;
...
< After Editing >
if MemTable.FieldByName('fieldname').OldValue<>MemTable.FieldByName('fieldname').NewValue then
<do something>
else
<do something else>

The problem is that MemTable.FieldByName('fieldname').OldValue allways return Null and not the old Value of the Field.

EhLib V5.6
Best regards

Nicholas
