Question

我总是收到自动完成JComboBox的错误。要自动完成我的jcombobox，请使用this的http://w_w.orbital-computer.de/JComboBox/脚本。当我创建它们时，我这样做：

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

如果我只使用新的jcomboboxes它会正常工作，但如果我改变它们的值如下：

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，另外列表中的第一个项目仍然有效，但是其他项目只是突出显示的文本的第一个字母，而不是出现错误。

AutoCompleteJComboBox.java是this file，第146行中有另一个名字

editor.setCaretPosition(this.getLength());

我希望有人能帮助我。
