  private void RunScript(object x, object y, ref object A)
  { 
    var field = new Grasshopper.Kernel.Types.GH_Field();
    var elem = x as List<IGH_FieldElement>;
    field.Elements.AddRange(elem);
    Print(field.ToString()); //returns a valid field.

    var name = "TEST";

    try
    {
      var arc = new GH_Archive();
      var res = arc.AppendObject(field, name);
      var xml = arc.Serialize_Xml();

      var field2 = new Grasshopper.Kernel.Types.GH_Field();
      var arc2 = new GH_Archive();
      res &= arc2.Deserialize_Xml(xml);
      res &= arc2.ExtractObject(field2, name);
      A = res;
      Print(field2.ToString()); // returns an empty field.
    }
    catch(Exception e)
    {
      Print(e.ToString());
    }
  }

I need to recover a GH_Field from xml but its deserialization doesn’t work or I don’t know how. I tried with the Data Input and Data Output components and it doesn’t work either, so it seems to be a bug.
