IW15-Incorrect filelist in IWFileUploader

[v.lasquibar@telefonica.net]

Hi,
I'm using Delphi 10.2 update 3, and recently installed version 15.1.0  of IW. I also use last version of TMS Intraweb controls.
In an application I have a IWFileUploader control, with default values in properties (unless the name, of course).
When I run my application, I drag an drop several files (they appears as "uploaded"), and after the user performs some operations, I will try to copy to another location, using this code:

if CargarFicheros.FileList.Count > 0 then
  begin
    for I := 1 to CargarFicheros.FileList.Count do
    begin
      FormaNombreFicheroDestino(I, FicheroDestino);
      CargarFicheros.SaveToFile(CargarFicheros.FileList[I - 1].FileName, FicheroDestino, True);
    end;
  end;


FormaNombreFicheroDestino is:

FicheroDestino := RutaFicheros_Presupuestos + 'P' +
                      Serie_Presupuestos + '_' +
                      CabPresupuestoCliente.cpr_nro.ToString + '#' +
                      I.ToString + '_' +
                      CargarFicheros.FileList[I - 1].FileName;



I have 2 problems:
a) FileList has only one element, regardless the number of files I've uploaded
b) When I refer to FileList [0].FileName, I get an Access Violation (whilst the element 0 of the list is not nil)

Could you please help me with this error?

Best regards,
