Application didn't start !!!

Hello everyone, I am testing this Titanium code:

Titanium.UI.setBackgroundImage("#000");
 
 
var tabGroup = Titanium.UI.createTabGroup();
 
var myWindow = Titanium.UI.createWindow({
 
    title:"Tours",
    backgroundColor:"#FFFFFF"
 
});
 
var myTab = Titanium.UI.createTab({
 
    icon:"KS_nav_ui.png",
    title:"Pays et capitales",
    window:myWindow
});
 
 
var myData=[
{title:"First picture",leftImage:"images/pic1.png",className:"tableRow",hasDetail:true,js:"css.js",datatoPass:"Original Data"},
{title:"Second picture",leftImage:"images/pic2.png",className:"tableRow"},
{title:"Third picture",leftImage:"images/pic3.png",className:"tableRow",hasDetail:true},
{title:"Fourth picture",leftImage:"images/pic4.png",className:"tableRow",hasDetail:true},
];
 
 
var myTableView = Titanium.UI.createTableView({
 
    data: myData
 
});
 
myWindow.add(myTableView);
 
myTableView.addEventListener("click", function(e){
 
    if (e.source.hasDetail){
        //Load new window
        if(e.source.js){
            var m = Titanium.UI.createWindow({
                title:e.source.title,
                backgroundColor:"#FFFFFF",
                dataToPass:e.source.dataToPass,
                url:e.source.js
            });
        }
        else{
            var m = Titanium.UI.createWindow({
                title:e.source.title,
                backgroundColor:"#FFFFFF",
 
            });
            var myLabel = Titanium.UI.createLabel({
 
                text:"New label created from the "+e.source.title,
                width:"auto",
                height:"auto",
                textAlign:"center"
            });
 
            m.add(myLabel);
        }
        myTab.open(m,{animated:true});
    }
    else
    {
        alert("No window to open :(")
 
    }
 
});
 
tabGroup.add(myWindow);
tabGroup.add(myTab);
 
tabGroup.open();

The problem is that the application didn't show up... the emulator start but not my application!

what's wrong with it?

thanks in advance!

it didn't work ... :(

I thought that I have made a mistake into the code itself, because I didn't get the application started, here is the code, can anyone tell me what's wrong with it?

Titanium.UI.setBackgroundImage("#000");
 
 
var tabGroup = Titanium.UI.createTabGroup();
 
var myWindow = Titanium.UI.createWindow({
 
    title:"Tours",
    backgroundColor:"#FFFFFF"
 
});
 
var myTab = Titanium.UI.createTab({
 
    icon:"KS_nav_ui.png",
    title:"Pays et capitales",
    window:myWindow
});
 
 
var myData=[
{title:"Picture1",leftImage:"images/pic1.png",className:"tableRow",hasDetail:true,js:"css.js",datatoPass:"Original Data"},
{title:"Picture2",leftImage:"images/pic2.png",className:"tableRow"},
{title:"Picture3",leftImage:"images/pic3.png",className:"tableRow",hasDetail:true},
{title:"Picture4",leftImage:"images/pic4.png",className:"tableRow",hasDetail:true},
];
 
 
var myTableView = Titanium.UI.createTableView({
    data: myData
});
 
myWindow.add(myTableView);
 
myTableView.addEventListener("click", function(e){
 
    if (e.source.hasDetail){
        //Load new window
        if(e.source.js){
            var m = Titanium.UI.createWindow({
                title:e.source.title,
                backgroundColor:"#FFFFFF",
                dataToPass:e.source.dataToPass,
                url:e.source.js
            });
        }
        else{
            var m = Titanium.UI.createWindow({
                title:e.source.title,
                backgroundColor:"#FFFFFF",
 
            });
            var myLabel = Titanium.UI.createLabel({
 
                text:"New label created from the "+e.source.title,
                width:"auto",
                height:"auto",
                textAlign:"center"
            });
 
            m.add(myLabel);
        }
        myTab.open(m,{animated:true});
    }
    else
    {
        alert("No window to open :(")
 
    }
 
});
 
myWindow.add(myTableView);
tabGroup.add(myTab);
 
tabGroup.open();

Thanks
