Disabling a button in 2.0.2

From the 2.0.2 new features list I understood we can now disable all controls. Does anyone know how to enable/disable a button? I tried the following:

var obj = new AW.UI.Button;
obj.setControlText("Button1");

obj.onClick= function() {
alert("Button clicked");
}

obj.setAttribute('disabled', 'true');
document.write(obj);
----
This however disables the button text but still allows you click on it. In addition it still highlights when you move the mouse over it.

Please advice.

Should be

obj.setControlDisabled(true);

see also /examples/controls - all/disable.htm

Sometimes life is easy.

Thanks a lot
