Spring Webflow: ошибка отображения представления java.lang.UnsupportedOperationException в javax.faces.context.ExternalContext.getClientWindow

Question

Я использую моджарру 2.2, gf4, swf 2.3.2.

Проблема возникает при загрузке страниц в веб-потоке. ошибка возникает, когда webflow (я думаю) отправляет страницы лицам для рендеринга. Я попытался с SWF2.0.8 до текущего SWF2.3.2.

который я позаимствовал откуда-то

всякий раз, когда я пытаюсь открыть страницу, я получаю эту ошибку

Answer 1

У меня та же проблема на Tomcat 6. В текущих стабильных выпусках Spring WebFlow неправильно реализован API-интерфейс JSF 2.2. Вот почему призывать javax.faces.context.ExternalContext.getClientWindow(...) выходит из строя. Источник проблемы, кажется, clientWindowId особенность.

Единственное решение для этого - обновить библиотеки Spring Webflow до версии 2.4 SNAPSHOT. Я взял библиотечные файлы с http://maven.springframework.org/snapshot/org/springframework/webflow. My Spring Framework является последней стабильной версией.

Примечание для пользователей Tomcat. Spring Webflow 2.4 теперь требует некоторых функций Java EE. В вашем проекте должна быть реализация спецификации CDI. Библиотека Weld очень хорошо подходит для реализации этой спецификации на серверах, которые не совместимы с Java EE (для получения дополнительной информации см. http://www.seamframework.org/Weld).

Answer 2

Это ошибка в SWF 2.3.2: она не поддерживает JSF 2.2

Вот отчет об ошибке: https://jira.spring.io/browse/SWF-1613

Начиная с 2.3.3 это исправлено.
