Appcelerator simple textfield not showing

Greetings,

I'm trying to simply display a blank textfield (I know), but it's not working?

I must be making some simple error.

Here is开发者_开发百科 my app.js:

Titanium.UI.setBackgroundColor('#FFF');

var win1=Titanium.UI.createWindow({  
    title:'Login',
    backgroundColor:'#FFF'
});

var uname = Titanium.UI.createTextField({
    color:'#336699',
    height:35,
    top:50,
    width:250,
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED
});

win1.add(uname);

Am I missing something? The above should work, right?

I'm using Android emulator on Ubuntu x86_64

When I use tabs the uname and label appear ok:

Titanium.UI.setBackgroundColor('#000');
var tabGroup = Titanium.UI.createTabGroup();

var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});
var tab1 = Titanium.UI.createTab({  
    icon:'KS_nav_views.png',
    title:'Tab 1',
    window:win1
});

var uname=Titanium.UI.createTextField({
    color:'#336699',
    height:35,
    top:50,
    width:250,
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED
});
var label1=Titanium.UI.createLabel({
    color:'#999',
    text:'hello',
    font:{fontSize:20,fontFamily:'Helvetica Neue'},
    textAlign:'center',
    width:'auto'
});

win1.add(uname);
win1.add(label1);

tabGroup.addTab(tab1);
tabGroup.open();

But how do I get rid of the tabs???

I've tried several versions of Android (1.6 API and 2.2 API)

Many thanks in advance,

Update: the solution is: Add the following line: win1.open({fullscreen:true});

is this on the end of you app.js

win1.open({fullscreen:true});
