Auto Completing JComboBox のエラーが常に発生します。jcombobox をオートコンプリートするために、 http://w_w.orbital-computer.de/JComboBox/のスクリプトを使用しました。それらを作成するときは、次のようにします。

final Object[] elements = new Object[] {"Please refresh your list"};
comboBox[i] = new JComboBox(elements);
comboBox[i].setEditable(true);                                  
new AutoCompleteJComboBox(comboBox[i]);

新しいjcomboboxesで使用するだけで問題なく動作しますが、値を次のように変更すると:

comboBox[i].removeAllItems();    
comboBox[i].setModel(new JComboBox<>(ListWithNames).getModel());
comboBox[i].setEditable(true);
new AutoCompleteJComboBox(comboBox[i]);

次のエラー メッセージが表示されます。

この位置 11 は、ListWithNames の最初の値の長さです。さらに、リストの最初の項目は正常に機能しますが、他の項目によって強調表示されたテキストの最初の文字にすぎず、エラーが表示されます。

AutoCompleteJComboBox.java は、 146 行目の別の名前のこのファイルです。

editor.setCaretPosition(this.getLength());

誰かがこれで私を助けてくれることを願っています。
