コントロールの2つの異なるアンダークラス（ComboBox、Textfield）を持つjavafx.scene.control.Control（ArrayList）のArrayListがあります。
そのため、両方の新しい入力(例)でリストを更新したいと考えています。
しかし、試してみると、Eclipseは次のようなエラーを出します:
Exception in thread "JavaFX Application Thread" java.lang.ClassCastException: javafx.scene.control.ComboBox cannot be cast to javafx.scene.control.TextField

編集: 2 つの区切られたリストで試すことができます。1 つはコンボボックス用、もう 1 つはテキストフィールド用です。
編集 2: 2 つの Arraylists で動作しています!! :))
