Sorry, No change,

Small TIBOQuery called TEST hookedup to Grid

'select * from test for update'

CREATE TABLE TEST (
A INTEGER NOT NULL
, b INTEGER
, c INTEGER
, d INTEGER
,
PRIMARY KEY ( A )
)

1. 'Delete from test'
2. TEST.IB_Transaction.Commit;

3. TEST.Prepare;
4. TEST.Open;
// Grid shows an empty data set
5. TEST.Append;
6. TESTA.value := 1;
7. TEST.Post; // Grid shows A = 1


8. TEST.IB_TRansaction.RollBack;
9. if TEST.IsEmpty then
ShowMessage('Empty'); // Never gets displayed

10.TEST.Refresh; // if this statement is not executed the
grid will not refresh and show an empty
dataset


Hope this helps.
Best regards,
Hans
