Serialize data from ListDataProvider?

Hi,

I just tried serializing data using ListDataProvider.getData();
Which returned a RPC exception, because this would return a ListWrapper implements List<T>.

And as the gwt ListWrapper does not implement Serializable itselft, this fails.

Thus, what is best extracting the data to a serializable list? Create a new ArrayList > addAll() > and then serialize?

List<Foo> serializeList = new ArrayList<Foo>().addAll(listDataProvider.getData());

Could I do better?
