Titanium gradient for buttonbar

Doesn't seem that the gradient works for the buttonbar either. So here is the workaround:

myButtonBar = Ti.UI.createButtonBar({
id:'buttonbar',
height:40,
backgroundColor:'#663399',
style:Titanium.UI.iPhone.SystemButtonStyle.BAR,
labels:['Close Keyboard >']
});

Just use a background color and the Titanium.UI.iPhone.SystemButtonStyle.BAR as the style -- and the app will create a gradient for you -- from lighter to darker.
