@Embedded objects in NoSQL/Mongo are persisted inside array containers [message #1122454]

We are getting a result (this is conceptual code):

@Embeddable
class Address{
String street;
}

@Entity
class Person{

@Field
String name;

@Field
@Embedded
Address address
}

When we persist a Person, the Mongo object/JSON has the embedded Person wrapped in an Array, a Person instance in Mongo looks like

{
"name" : "John",
"address": [{"street": "Elm Street"}]
}

We don't want this extraneous array, any way to prevent this? We need it gone for backwards data compatibility. I.e, we want it to look like:

{
"name" : "John",
"address": {"street": "Elm Street"}
}

Thanks to anyone who has any advice on this!
