Answer 1

ErMasca正確地指出了一個錯誤。

同樣在您的ContentPart中，您將需要使用Record.SourceRecord來訪問導航屬性。

public SourceRecord Source() 
{ 
    get { return Record.SourceRecord; } 
    set { Record.SourceRecord = value; } 
} 

Answer 2

http://docs.orchardproject.net/Documentation/Creating-1-n-and-n-n-relations 儘管如此，在你的觀點下拉並不真的保持SourceId，不是嗎？ 轉到：

@Html.DropDownListFor(model => model.SourceId, 
         Model.Sources.Select(s => new SelectListItem 
         { 
          Selected = s.Id == Model.SourceId, 
          Text = s.Type , 
          Value = s.Id.ToString() 
         }), 
         "Choose a Source...") 

將允許能夠再次覈對表。
