Crie un Form y solo puzo componentes en el. Que passa, es simpre que me voy abrir el Form me viene un error de Access Violation. Y abre una Unit llamada dxBar. Esta es la funccion que se abre en el error:

Código Delphi [-]
function TdxBarManager.BarByComponentName(const AName: string): TdxBar;
var
  I: Integer;
begin
  Result := nil;
  for I := 0 to Bars.Count - 1 do
    if Bars[i].Name = AName then
    begin
      Result := Bars[i];
      Break;
    end;
end;

Yo no tengo ninguno BarManager o algo parecido.
Mi Form:

unit uCadClie;
