リストビューがあり、そのリストビューの中に
EnumdropDrop - テキストフィールド - DropdownChoice - Ajaxbutton | すべてのアイテムに
最初のドロップダウンは通貨で、2 番目はアカウント オブジェクトです。アカウント ドロップダウンの選択肢の 1 つは、通貨にちなんで名付けられた新しいアカウントを作成することです。
新しいアカウントが作成されると、アカウントのドロップダウンで選択された値になります。
これは最初のアカウントでは正常に機能しますが、2 つ目以降の新しく作成されたすべてのアカウントは正しく作成され、可能性のリストに追加されますが、それらは選択されたアカウントではありません。ajaxを更新するたびに、新しく作成されたすべてのアイテムで選択されたアカウントが最初に作成されたアカウントとして設定されます。面白いのは、フォームを送信すると、アカウントの選択が正しいことです。
