IModel<String> m =
LoadableDetachableModel
.of(Person::new)
.map(Person::getName);
So much sexiness with lambda's and models...
IModel<Account> a = ...;
IModel<Person> p = a.map(Account::getPerson);
add(new Label("firstName", p.map(Person::getFirstName));
add(new Label("lastName", p.map(Person::getLastName));
Too bad Java doesn't have properties as a language construct. That
would make this even better:
IModel<Account> a = ...;
IModel<Person> p = a.map(Account::person);
add(new Label("firstName", p.map(Person::firstName));
add(new Label("lastName", p.map(Person::lastName));
