        if( ((Boolean)value).booleanValue() ) {
            setText("Yes");
        } else {
            setText("No");
        }
        return this;
    }
    public Component getListFocusComponent(List list) {
        return label;
    }
}
Form f = new Form("ListRenderer", new BorderLayout());
List<Boolean> lst = new List<Boolean>(Boolean.TRUE, Boolean.FALSE);
f.addComponent(BorderLayout.CENTER, lst);
