My experience says sort handler (i.e. ListHandler) is sensitive to the List, which ListDataProvider has, when you are creating it.

So I recommend not to delete or set new List for ListDataProvider (of course I think it should has at least an empty (not null) list when you are creating).

Just use ListDataProvider.getList() and do your jobs on it.

For example for removing all current rows and setting new data, just call ListDataProvider.getList().clear() and then ListDataProvider.getList().addAll(yourNewData); do not call setList() or the sorting becomes not working.
