Summary0005531: [TJvCustomCsvDataSet] fkLookup FieldKind field not updating
DescriptionHi,
a field whose FieldKind property is set to fkLookup is supposed to update when another field pointed by KeyFields property is changing.
But it is not.
Additional InformationTo fix it, I suggest, in TJvCustomCsvDataSet.SetFieldData, not to skip the "DataEvent(deFieldChange, Longint(Field));" call
More precisely, here is a code proposal:
in procedure TJvCustomCsvDataSet.SetFieldData(Field: TField; Buffer: Pointer);
instead of:
...
    if AnsiChar(PDestination[0]) <> #0 then
      Move(Buffer^, PDestination[1], Field.DataSize);
    //Result := True; {there is no return value, oops}
    Exit;
  end;
...

it should be:
...
     if AnsiChar(PDestination[0]) <> #0 then
      Move(Buffer^, PDestination[1], Field.DataSize);
    //Result := True; {there is no return value, oops}
  end else begin
...
  end;
  // Notify controls of a field change:
  DataEvent(deFieldChange, Longint(Field));

I've solved it a little bit different, but it's now in svn.

Please verify.
