objectify filter with ancestor not working

Objectify filter with ancestor is not working, check below code:

List<AccountGroupEntity> list = ofy().load()
                .type(AccountGroupEntity.class)
                .ancestor(Key.create(BusinessEntity.class, bid)).filter("accountGroupType=", type)
                .list();

While this is a terrible question - you should explain what you mean by "it doesn't work" - the problem is almost certainly that you are filtering by the exact literal value "accountGroupType=". You need a space before the '='.
