Mr. Jason... I did the fix below:



procedure TIB_BDataset.SysCancelInsertedRow;
begin
SysAdjustCurrentRow( true, true );

//cezinha - begin
FCurrentCursor.Fields.RefreshBuffers(false, true, false);
//cezinha - end
end;


Could you confirm if will I not have some problem in the future?

I'm waiting your answer anxiously!

Thanks so much

That is probably all it needs as this will reset the column buffers and
allow the blob contents to be pulled from the server so that the correct
data is shown.

I don´t what exactly is happening, but I call
qry.Fields.RefreshBuffers(true, true, true); and everything looks right.

qry.Append;
qry.FieldByName('obs_codigo').AsInteger := codigo;
qry.FieldByName('obs_nome').AsString := nome;
qry.FieldByName('obs_observacao').AsString := nome;
qry.Post;
qry.Append;
qry.FieldByName('obs_observacao').AsString := '***** SEE HERE!!!
*****';
qry.Cancel;
qry.Fields.RefreshBuffers(true, true, true);

I'll continue studing the source!

If someone knows what is happening, please, help-me!
