container#addElement accepts objects of type Object. Betwixt needs to
know the candidate classes which may be included in that collection.  

you need to use a polymorphic mapping. read
http://jakarta.apache.org/commons/betwixt/guide/reading.html#Reading%
20Polymorphic%20Mappings. 

i haven't managed to track down the exact mapping you need but i'll try
to do that at the weekend.
