Сегодня утром я пришел в свой офис и первым делом увидел: моя компания сайт разбился. Из-за меня я думаю.java.lang.ClassCastException: com.sun.faces.facelets.compiler.UIInstructions нельзя передать в org.primefaces.model.menu.MenuElement
Теперь я пробовал на полтора часа, чтобы исправить это, но я ничего не нашел, и все теряет сознание, потому что сайт не работает, и я не могу его исправить (я один. Создатели сайт ушел или в отпуске). Поэтому я надеюсь, что ты поможешь мне!
Я получаю это исключение, когда я вызываю dashboard.xhtml своего сайта.
java.lang.ClassCastException: com.sun.faces.facelets.compiler.UIInstructions cannot be cast to org.primefaces.model.menu.MenuElement
Моя проблема: во всем исключении нигде нет файла, который я сделал сам. Поэтому я действительно не знаю, где именно моя ошибка.
Вы можете мне помочь?
Вот некоторые дополнительные сведения:
Всего исключение:
