nope. you're missing the point. there's no header object involved. we save an instance of /some/ object that implements list for every form component in wicket. what's more,
when we have only one validator, there is no overhead at all.

Well, right now you're doing exactly what LinkedList does. You're
wrapping every object in a node and including two object references.
Where's the space savings? You could get rid of half the objects by
using an array and essentially reimplementing ArrayList. The downside
here is that if I add a string validator to a RequiredTextField, I
have no gaurantees that the value I get will be non-null.

I do like what you did with the booleans though. That's tight. :)
