Look carefully at the ListView's constructor arguments. It wants an IModel<List<Cheese>>, not an IModel<Cheese> which is what your current CheeseDetach provides. Depending on your goals, you can either (1) change CheeseDetach.load() to call getCheeses(), or (2) change the constructor to accept a list of cheeses and retain a list of cheese IDs, and query for those cheeses individually in CheeseDetach.load().
