Ссылка метод пожаров несколько нет. раз

Проблема заключается в том, что всякий раз, когда я нажимаю ссылку Next на странице Home.xhtml на страницу getMoreStatusList, функция getMoreStatusList вызывается без остановки, пока не вытащит индекс из связанного исключения. Я даже печатаю значение индекса, которое я получаю от объекта сеанса statusindex, и строки ingetmorestatusList, когда внутри метода getMoreStatusList() на консоли, я использую метод results = results.subList(index,index+5);, чтобы создать подсписку, но эта строка получает вызов более одного раза и выкидывает связанного исключения, поскольку значение индекса увеличивается с каждым вызовом.Ссылка метод пожаров несколько нет. раз

Я сомневаюсь, что количество записей в tabke 'Staus' всегда кратно пяти. так что происходит, когда у вас есть 17 записей? вы получите 3 раза 5 при 4-й попытке, только 2 напоминают так: «results.subList (index, index + 5)» будет вызывать «IndexOutOfBoundsException». вам нужно проверить, превышает ли индекс + 5' размер списка, если да передать 'results.size()' вместо – A4L

Я. вы правы, я добавлю инструкцию If, чтобы преодолеть эту проблему, но до сих пор не получаю это почему метод getMoreStatusList() получает вызов более одного раза, когда я просто нажимаю ссылку на страницу getMoreStatusList, которая должна запускать функцию getMoreSatusList() на странице Home.xhtml –

: http://stackoverflow.com/ Вопросы/2090033/why-jsf-calls-getters-multiple-times – 757071

Вы должны использовать <ui:repeat> (с xmlns:ui="http://java.sun.com/jsf/facelets") вместо <c:forEach>

foEach является обработчик тега, repeat является компонентом. Вы можете прочитать больше о разнице между этими двумя на этом blog

избавиться от IndexOutOfBoudsException использовать следующее getMoreStatusList:

int index = (Integer) session.getAttribute("statusindex"); 
int end = index+5 > results.size() ? results.size() : index+5; 
List<Status> subList = results.subList(index,end); 
session.setAttribute("statusindex", end);

и в getStatusList:

int index = 0; 
int end = index+5 > results.size() ? results.size() : index+5; 
List<Status> subList = results.subList(0, end);

Я понимаю все, что вы написали, то, что я не понимаю, является то, почему getMoreStatusList() вызывается более одного раза, так как я нажимаю только ссылку. –

ссылка запускается только один раз, вызовы метода bean происходят на сервере несколько раз. прочитайте раздел «Несвязанный» этого ответа http://stackoverflow.com/questions/8903483/cforeach-returns-only-one-empty-value – A4L

'int index = (Integer) session.getAttribute (" statusindex "); \t \t int end = index + 5> results.size()? results.size(): index + 5; System.out.println ("Значение индекса и конец в getMoreStatusList" + индекс + "" + конец); Список subList = results.subList (индекс, конец); session.setAttribute ("statusindex", end); ' Я добавил дополнительную строку для кода, предложенного вами, значение индекса и конца всегда равно 20 и 20 –

Ссылка метод пожаров несколько нет. раз
