Hello Raphaele,
As the ObjectRepresentation wraps another Representation to deserialize,
and because the 2 distinct formats are supported, you should help the
objectRepresentation to know which deserializer is going to be used.
If you are using the following constructor, juste set the media type of the
wrapped representation
public ObjectRepresentation(Representation)
best regards,
Thierry Boileau
