problem with CachedUpdates and appending records
Posted: Fri 09 Jan 2009 09:19
Hello,
I have installed ODAC 6.70 in Delphi 2006 and noticed the following
problem: if I use VirtualTable component with CachedUpdates then
new appended records will never be applied.
It seems that records appended in cache mode will always get urFail flag
thus they will never be committed and disappear after CancelChanges.
here is the code demonstrating the problem:
Could you please fix it?
Thank you and regards

Code: Select all
VirtualTable1.CachedUpdates := true;
VirtualTable1.Open;
for i := 1 to 3 do
begin
VirtualTable1.Append;
VirtualTable1.Post;
end;
VirtualTable1.CommitUpdates;
Assert(VirtualTable1.RecordCount = 3);
VirtualTable1.CancelUpdates;
// after CancelUpdates RecordCount will be 0
// but it should be 3, as we already committed updates
Assert(VirtualTable1.RecordCount = 3);Could you please fix it?
Thank you and regards
