var win1 = Titanium.UI.createWindow({
	title : 'Tab 1',
	backgroundColor : '#fff'
});

var g_backgroundGradient = {startPoint: {x:0, y:0}, endPoint: {x:400, y:600}, colors:['blue', 'orange'], type: 'linear'};

var backview = Titanium.UI.createView({
	backgroundGradient : g_backgroundGradient // <<< COMMENT OUT THIS LINE TO FIX PROBLEM
});

var view1 = Titanium.UI.createView({
	backgroundColor : 'red',
	width : '300',
	height : '400',
	left : 15,
	top : 15,
	zindex : 10,
});

var view2 = Titanium.UI.createView({
	width : '100',
	height : '70',
	left : 5,
	top : 5,
	backgroundColor : 'green',
	zindex : 1
});
backview.add(view1);
backview.add(view2);

win1.add(backview);

win1.open();
