wrong value in the TSQLRecord.FillCurrentRow property

I have this code that fills a StringGrid with the list of users

u := TSQLAuthUser.CreateAndFillPrepare(Controlador.Database, TInt64DynArray(ids));
  stringgrid1.RowCount := u.FillTable.RowCount;

  while u.FillOne do
  begin                             
    sgUsuarios.Cells[0, u.FillCurrentRow - 2] := IntToString(u.id);
    sgUsuarios.Cells[1, u.FillCurrentRow - 2] := u.LogonName;
  end;


This code works well, but I think I should use "u.FillCurrentRow - 1".

The constructor TSQLAuthUser.CreateAndFillPrepare set FillCurrentRow to 1, but when I call u.FillOne the FillCurrentRow is incremented.

source code:

function TSQLRecord.FillOne: boolean;
begin
  if (self=nil) or (fFill=nil) or (fFill.Table=nil) or
     (fFill.Table.fRowCount=0) or // also check if FillTable is emtpy
     (cardinal(fFill.FillCurrentRow)>cardinal(fFill.Table.fRowCount)) then
    result := false else begin
    FillRow(fFill.FillCurrentRow);
    inc(fFill.fFillCurrentRow);
    result := true;
  end;
end;

Is that correct?

Re: wrong value in the TSQLRecord.FillCurrentRow property

This is as documented.
But naming is indeed confusing.
It stores the next row number which would be filled, not the current row number.
