Re: Using generics with some non-generic classes in Wicket

[Jonathan Locke]

well, unless this:

  public class Label<T> extends WebComponent<T>

  public class Label extends WebComponent<String>

not saying this is the right thing to do as it might break a lot of code,
but it would be more precise.
