error using datastore with composite _id

[GoogleCodeExporter]

I have a class with another class as an _id field.
when doing save/insert via the BasicDAO, i get the following exception.
doing save insert via the collection itself works just fine.

What version are you using? (Morphia/Driver/MongoDB)
mongo 2.5 and morphia 1.0 snapshit
Please include a stack trace below:

@Embeded
public class Oid
{
 public Long x;
 public Long y;

public oID(Long x,Long y)
{
this.x = x;
this.y = y;
}
}

@Entity
public class Ent
{
  @Id
  Oid id;
  public ent(Oid id)
{
  this.id = id;
}
}
Morphia morphia = new Morphia().map(Ent.class)
new DatastoreImpl(morphia,mongo).insert(new Ent(new Oid(1l,2l)));

the object is saved just fine, but the above exception is thrown

the last line where the datastore creation is should be.
morphia.createDatastore(mongo,"test").save(new Ent....;
