Objekte in TreeView

[CalganX]

Hi,
ersteinmal der Source (das mit try...finally kommt noch):

Delphi-Quellcode:

// ------ Fileoperations -- start -----

//Erweiterung entfernen
function GetToken(aString, SepChar: string; TokenNum: Byte): string;
var
  Token: string;
  StrLen: Byte;
  Num: Byte;
  EndofToken: Byte;
begin
  StrLen     := Length(aString);
  Num        := 1;
  EndofToken := StrLen;
  while ((Num <= TokenNum) and (EndofToken <> 0)) do
  begin
    EndofToken := Pos(SepChar, aString);
    if EndofToken <> 0 then
    begin
      Token := Copy(aString, 1, EndofToken - 1);
      Delete(aString, 1, EndofToken);
      Inc(Num);
    end
    else
      Token := aString;
  end;
  if Num >= TokenNum then
    Result := Token
  else
    Result := '';
end;

function getAllFiles(path: string): TStringList;
var
  tempResult: TStringList;
  s: string;
  i   : integer;
  stl : tstringlist;
  lastindex: integer;
begin
  tempResult := TStringList.Create;
  s := path;
  stl:=tstringlist.Create;
  lastindex := -1;
  try
    for i := 0 to tempResult.count - 1 do
    begin
      stl.Add(GetToken(tempResult.strings[lastIndex], '.', 1));
      inc(lastIndex);
    end;
    tempResult.CommaText:=stl.commatext;
  finally
    stl.Free;
  end;
  result := tempResult;
end;

// ------ Fileoperations -- end   -----

procedure updateList(TreeView: TTreeView);
var
  langs: TStringList;
  entries: TStringList;
  newMainNode: TTreeNode;
  newLangNode: TTreeNode;
  i, j: integer;
begin
  langs := TStringList.Create;
  langs.LoadFromFile(MAIN_PATH+'languages.clf');
  langs.Sorted := true;
  TreeView.Items.Clear;
  newMainNode := Treeview.Items.Add(nil, 'CodeLib');
  for i := 0 to langs.Count-1 do begin
    newLangNode := TreeView.Items.AddChild(newMainNode, langs[i]);
    entries := TStringList.Create;
    entries := getAllFiles(MAIN_PATH+langs[i]+'\*.*'#0);
//    ShowMessage(IntToStr(entries.count)+#13#10+MAIN_PATH+langs[i]+'\*.*'#0);
    for j := 0 to entries.Count do begin
      TreeView.Items.AddChild(newLangNode, entries.Strings[j]);
    end;
    entries.Free;
  end;
end;

So, wenn ich nun in der FormCreate-Methode "UpdateList" schreibe, dann kommt der Fehler "ListIndex out of bounds(0)".
Das kann aber nicht sein, da das Verzeichnis nicht leer ist... Was isr falsch?
