Cool, that looks sensical to me. I like how I don't have to actually
have the stars in my html file. But one thing - the isEnabled() method
does not exist in the AbstractBehavior class. But I think the
following will work:
label.add(new AbstractBehavior() {
@Override public void onRendered(Component component) {
if (starIsVisible) {
Response response = component.getResponse();
response.write("<span id='foo' class='bar'>*</span>");
}
}
});
