我总是收到自动完成 JComboBox 的错误。为了自动完成我的 jcombobox，我使用了http://w_w.orbital-computer.de/JComboBox/这个脚本。当我创建它们时，我会这样做：

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

如果我只是将它与新的 jcombobox 一起使用，它就可以正常工作，但是如果我像这样更改它们的值：

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

我收到以下错误消息：

这个位置 11 是 ListWithNames 中第一个值的长度，此外，列表中的第一项仍然可以正常工作，但其他项只是突出显示的文本的第一个字母，然后出现错误。

AutoCompleteJComboBox.java 是这个文件在第 146 行的另一个名称是

editor.setCaretPosition(this.getLength());

我希望有人可以帮助我。
