MessageType deserialization issue

[arsenalol1]

Hi !

I encoutred a problem with deserialization of the attribute ResponseMessage.type . When I deserialize a Json like this one :
"fulfillment": { "speech": "Howdy.", "messages": [ { "type": 0, "speech": "Howdy." } ] },
the attribute 'type' of ResponseMessage.ResponseSpeech is null.
Here is my code :
ResponseSpeech re = (ResponseSpeech)GsonFactory.getDefaultFactory().getGson().fromJson("{ \"speech\": \"Hey!\",\"messages\": [{\"type\": 0,\"speech\": \"Howdy.\" }]}", Fulfillment.class).getMessages().get(0);

Thanks !

The field ResponseMessage.type is private and not supposed to be used outside of the class.

How do you use it?

I checked the value with the debugger ^^.
