在我的 ADF 应用程序中，有一个具有两个主要方面的基本页面模板 - leftNav 和 center。包含按钮的页面片段 mainNav.jsff 添加到 leftNav。根据单击的按钮，页面片段显示在中心方面。

一切正常，但我面临一个问题，如果我单击 mainNav.jsff 中的一个按钮并且发生任何异常，那么所有其他按钮都会停止工作并引发相同的异常。

我正在使用 JDeveloper 11.1.2.3 和 Weblogic 11gR1。我只使用 ADF Faces。为什么会出现这个异常，我该如何解决这个问题？

编辑：当前例外是

在页面视图参数中，而不是#{sessionScope.Temp}您可能已经给出#(sessionScope.Temp}

错误的大括号()代替{}，请检查。我有同样的问题，经过长时间的调试解决了。

让我们解码您的堆栈跟踪：

javax.el.PropertyNotWritableException
...
TaskFlowCallActivityLogic.setInputValues()
...
TaskFlowCallActivityLogic.enterTaskFlow()

您通过将输入参数传递给任务流来从菜单打开任务流，并且此参数是只读的。如果它们与支持 bean 相关联，您可以检查您的任务流参数并使其全部可编辑。

看起来您正在将参数传递到页面或任务流之间，并且 EL 不正确。

这是JDev中的屏幕截图

你也可能有“scope.variable”而不是“#{scope.variable}”
