Hi,

I am trying to persist and ArrayList, but it does not work. Everything
is great locally [M/S db], but when I deploy it [HR] then objects do
not persist. Any ideas why? It's really weird and I cannot find any
solution.

I use Guice for injections, here is required code:

@Persistent(defaultFetchGroup = "true", serialized="true")
        private ArrayList<ArrayList<Long>> colonisations = new
ArrayList<ArrayList<Long>>();

at User class


Another class, that tries to persist the data:


@Inject
        public Repository<User> userRepo;

...
...
MySession.get().getUser().getColonisations().add(colonisation);
...
...
Colonisation.this.userRepo.persist(MySession.get().getUser());
