Доброго всем времени суток. Пытаюсь выполнить такой вот код (при нажатии на кнопку): | Код |
DefaultListModel model = (DefaultListModel)jList.getModel();
|
где jList - объект класса JList. Все это дело компиллируется, но на вышеописанной строке вылазит ексцепшн: | Код |
Exception occurred during event dispatching:
java.lang.ClassCastException: javax.swing.JList$3 cannot be cast to javax.swing.DefaultListModel

Нагуглить чего либо внятного по этой теме не смог. З.Ы. Делаю я это чтобы можно было добавлять и удалять один элемент в/из список/списка. Подскажите плс в чем дело, по идее никаких ошибок быть не должно, на этом форуме и не только видел примеры такого кода. Заранее спасибо.

(DefaultListModel)jList.getModel() выдает ошибку
