DropDownChoice models

[Zbynek Vavros]

Hey,

I have a DropDownChoice for list of users. I want to display user's name
but bind user's ID.
So far I have come to this (ugly) solution that can surely be improved:

// create model with Long userId...
final DropDownChoice<Long> usersDropDown = new DropDownChoice<>(
                    "userId", Lists.transform(User.getUsers(), new
Function<User, Long>() {
                @Nullable
                @Override
                public Long apply(@Nullable final User user) {
                    return user.getId();
                }
            }),
                    new ChoiceRenderer<Long>() {
                        @Override
                        public Object getDisplayValue(final Long id) {
                            return User.findOne(id);
                        }
                    }
            );

Thanks for any pointers.
