基本的な ListB へのルックアップ フィールドを持つコンテンツ タイプ TypeA を作成しました。次に、TypeA を使用する ListA を作成します。すべてがプログラムで作成されます。
ListA の「新しい項目の追加」モーダルが読み込まれるはずのときに、例外がスローされます。ListB に項目がある場合にのみ発生します。ListB が空の場合、listA の「新しい項目を追加」モーダルが読み込まれ、ListB へのルックアップ フィールドが正しく表示されます。(None)

コンテンツ タイプ、リスト、ルックアップ フィールドの作成に使用する方法:
private SPContentType createContentType(SPSite site, string typeName, string groupName, string parentTypeName, string[] fields) {
try {
SPContentType testExist = site.RootWeb.ContentTypes[typeName];
if (testExist != null)
return testExist;
}
catch { }
SPContentType parentType = site.RootWeb.ContentTypes[parentTypeName];
SPContentType contentType = new SPContentType(parentType, site.RootWeb.ContentTypes, typeName);
contentType.Group = groupName;
foreach (string field in fields) {
contentType.FieldLinks.Add(new SPFieldLink(site.RootWeb.GetField(field)));
}
contentType.FieldLinks["Title"].Required = false;
contentType.FieldLinks["Title"].Hidden = true;
site.RootWeb.ContentTypes.Add(contentType);
contentType.Update();
return contentType;
}
public SPFieldLookup createLookupField(string fieldName, string groupName, Guid listGuid, string lookupField, bool allowMultipleValues, bool isRequired) {
if (site.RootWeb.Fields.ContainsField(fieldName))
return null;
string internalName = site.RootWeb.Fields.AddLookup(fieldName, listGuid, isRequired);
SPFieldLookup lookup = site.RootWeb.Fields.GetFieldByInternalName(internalName) as SPFieldLookup;
lookup.AllowMultipleValues = allowMultipleValues;
lookup.LookupField = lookupField;
lookup.Group = groupName;
lookup.Update();
return lookup;
}
public SPList createList(string listName, string description, SPContentType contentType) {
if (web.Lists.TryGetList(listName) != null)
web.Lists[listName].Delete();
Guid newListGuid = web.Lists.Add(listName, description, SPListTemplateType.GenericList);
SPList newList = web.Lists[newListGuid];
newList.OnQuickLaunch = true;
newList.Update();
newList.ContentTypesEnabled = true;
SPContentType newType = newList.ContentTypes.Add(contentType);
newList.Update();
newList.ContentTypes["Item"].Delete();
newList.Update();
newList.Fields["Title"].Required = false;
newList.Fields["Title"].Hidden = true;
newList.Fields["Title"].Update();
SPView view = newList.DefaultView;
foreach (SPField field in newType.Fields) {
view.ViewFields.Add(field);
}
view.ViewFields.Delete("Title");
view.ViewFields.Delete("LinkTitle");
view.ViewFields.Delete("ContentType");
view.Update();
return newList;
}
例
SPContentType typeB = createContentType(site, "Type B", "My Group", "Item", new string[] {"Salary"});
SPList listB = createList("List B", "my list b", typeB);
SPFieldLookup lookupB = createLookupField("B", "My Group", listB.ID, "Salary", false, false);
SPContentType typeA = createContentType(site, "Type A", "My Group", "Item", new string[] {"Name", "B"});
SPList listA = createList("List A", "my list a", typeA);
