Bad IWModalWindow.ButtonIndex in version 15.1

[v.lasquibar@telefonica.net]

Hi,

I've installed today version 15.1.0 of Intraweb and recompiled TMS components, and my applications. I have an application that shows a ModalWindow with 2 fields and 2 buttons (OK and Cancel), and check return using this code:

if Login_Modal.ButtonIndex >= 0 then begin   
  case Login_Modal.ButtonIndex of
      1: // Conectar
          ValidarUsuario;
    end;
  end;


The problem is that regardless the button I press, the value of ButtonIndex is always 2 (Cancel).
How can I do to know the button really pressed by the user?


Best regards,
