Impossible to open Screen.

Hi, i have a strange problem:

I have an app with several screens. Now i need a new screen. Then i doubled a file "index.js" and name the new "calefaccion.js", doubled "index.xml" and name the new as "calefaccion.xml". My problem is to open the new screen "calefaccion" from "index". In "index" i can open another screen but "calefaccion" is imposible.

I tried it on Android, (emulator and my smartphone).

The code is

index.js

var programacion = Alloy.createController('programacion').getView();
 
function AbreProg() {
    cierroMenulateral();
 
    $.BProg.setOpacity(0.3);
    setTimeout(function () {
        $.BProg.setOpacity(1);
    }, 200);
 
    programacion.open();
}
 
var calefaccion = Alloy.createController('calefaccion').getView();
 
function AbreCalefaccion() {
    cierroMenulateral();
 
    $.BCalefaccion.setOpacity(0.3);
    setTimeout(function () {
        $.BCalefaccion.setOpacity(1);
    }, 200);
    Ti.API.info('Abro la cale ' );
    calefaccion.open();
}

calefaccion.js

Ti.API.info( "Estoy en calefaccion.js 00");
 
 
function PosicionaBotones(){
 
    Ti.API.info( "Estoy en calefaccion.js PosicionaBotones");
 
}
 
 
$.calefaccion.open();

calefaccion.xml

<Alloy>
    <Window class="container" backgroundColor="#000" onOpen="PosicionaBotones" >
        <Label id="LConsumos" top="95%" center="87.5%" >Consumos</Label>
    </Window>
</Alloy>

When i run "AbreProg", then "programacion" is open. When i run "AbreCalefaccion", then "calefaccion" in don't open.

Why???

Or am I going crazy or Friday the 13th.

Any suggestions??

Thanks
