[Simple-support] Nested array list

[Ramiro d. C. <ram...@gm...>]

Hi folks I will need to serialize a nested arrayList like so:

@ElementList
protected ArrayList<ArrayList<MyClass>>

and I am getting TransformException: Transform of class java.util.ArrayList
not supported

Is there a way to implement this without having to wrap
the ArrayList<MyClass> inside a class?
My second approach was to try to use a Converter but as I need names for
the attributes, I can not figure out how to do it.

Thanks in advance
Ramiro
