The approach with
Component radio= new Radio("radio", ...);
is the right one. You can still try to add the AttributeModifier, but
probably, you'll end up fighting the Radio implementation (perhaps you'll
have to create a subclass?)
However, I don't see why you don't just use the regular wicket approach? Did
you actually measure that there is more load on the server? I highly doubt
it.
