             Summary: Model#orElse behavior is inconsistent!
                 Key: WICKET-6412
                 URL: https://issues.apache.org/jira/browse/WICKET-6412
             Project: Wicket
          Issue Type: Improvement
            Reporter: Jarosław


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?
