Re: users, please give us your opinion: what is your take on generics with Wicket

You could use Java's covariant return types to override getModel() to
return a specific type. Which would mean that you would need to subclass
to "simulate" generics (with a new subclass for each type). Also, when
using anonymous subclasses it becomes rather pointless and you'd be back
to casting.
