Я переношу проект со Struts 2.3.3 на Struts 2.5.12 и вижу NullPointerException при использовании метода getText из класса ActionSupport.
Мой класс действий расширяет класс ActionSupport. У меня есть файл package.properties, также упакованный в файл war.
Мой класс действий выглядит так:
public class MyAction extends ActionSupport {
private List<String> months = new ArrayList<>(
Arrays.asList(getText("date.month.default"), "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12"));
}
И в файле package.properties у меня есть
date.month.default=MM
Я вижу исключение ниже, когда создается экземпляр компонента для моего класса действия. Кто-нибудь знает, делаю ли я здесь что-нибудь не так?
