> Dear Wicket Devs,
> I was very confused by Model#orElse method.
> Model and Optional have similar methods and these methods behave the same:
> {code}
> Optional<Integer> _optional = Optional.ofNullable("1").map(Integer::parseInt);
> IModel<Integer> _model = Model.of("1").map(Integer::parseInt);
> {code}
> Unfortunately "orElse" behavior is totally confusing!
> {code}
> Integer integer = _optional.orElse(0);
> IModel<Integer> integerIModel = _model.orElse(0); //WRONG!
> {code}
> It should return a Model's Object instead of Model itself!
> This definitely break the least surprise rule, so can you please change that before Wicket8 final release?
