StackOverflowErr с примером DynaForm

Я получаю Stackoverflow, когда пытаюсь запустить пример DynaForm из ShowCase.StackOverflowErr с примером DynaForm

Я пробовал другие примеры, чтобы узнать, не сделал ли я ошибку при установке расширений. pe: analogClock и pe: график работает очень хорошо.

Не могли бы вы взглянуть и указать мне в правильном направлении?

Спасибо!

'StackOverflowError' будет происходить, когда есть бесконечная рекурсия. – BalusC

Согласен. Но где? Я провел все это воскресенье. Код копируется из витрин. – Duesentrieb

Где можно вывести путем анализа StackTrace и увидеть Wich «блок» повторяет – Kukeltje

Вы просто:

Изменение обновления на CommandButton <p:commandButton value="Submit" action="#{dynaFormController.submitForm}" update=":mainForm:dynaFormGroup" />обновления = ": MainForm: dynaFormGroup"
Добавить идентификатор на первом panelGrid <h:panelGroup id="dynaFormGroup" widgetVar="detail" id="detail">ID = "dynaFormGroup"
