If inviter is a required information then make it a constructor arg:
private final AsyncCallback<List<User>> loadUsersCallback;
public InvitationForm(final int inviter) {
loadUsersCallback = new AsyncCallback<List<User>>() {
void onSuccess(final List<User> users) {
fillList(users);
select(inviter);
}
}
}
@Override
protected void onLoad() {
super.onLoad();
service.getUsers(loadUsersCallback);
}
That's what I would have done, but maybe I don't get your use case
correctly ;-) So far I never really needed this
scheduleDeferredWhenServerCallReturned feature, as I already have it.. its
the onSuccess() method and I would rethink what I am doing until I can
implement onSuccess() the way it should be.
