FilterChain抛出javax.servlet.ServletException：IteratedExpression.getItem：索引超出界限

时间：2011-12-12 17:01:14

标签： java jsf richfaces servlet-filters

对于缺少代码示例表示抱歉，但我不确定是否可以在一个简单的示例中复制该问题。

以下例外最近已开始出现在我的RichFaces应用程序中。它是一个Web前端，用于查询数据库并在简单表中显示数据。当我的应用程序完成在链接到命令按钮的bean上执行我的代码时，会出现问题。当你单击弹出面板上的按钮调用FilterChain.doFilter，然后完成bean上的代码，然后我假设在尝试重新渲染主窗口时抛出此异常。

当一个新的入口点出现在同一个弹出式面板上，当单击该按钮时在bean上执行相同的代码时，问题就出现了，但是由于添加了这个新入口点，旧入口点已经开始抛出此异常。

我知道任何人都不可能在没有代码的情况下提供问题的答案，但对这些过滤器链如何工作几乎不了解，我甚至不确定从哪里开始寻找并且想知道是否有人可以指出我可能导致我找到解决方案的方向。

该服务正在WASCE 2.1上运行。

非常感谢任何帮助。

答案 0 :(得分：2)

问题解决了，试图重新呈现不存在的部分面板。奇怪的是它只发生在一个入口点是在jsp中作为弹出面板上的确认按钮的rerender属性所以两个入口点使用相同的按钮和jsp声明。添加在缺少的部分，因为它本来就在那里，只能想象它被错误地删除或者svn合并。

这绝对与过滤器无关。请求恰好通过过滤器传递。如果过滤器会引起任何问题，你会在堆栈跟踪的第一行看到它。

您的具体问题很可能是由于未在后续请求中保留数据表的正确数据模型而导致的。托管bean显然位于请求范围内而不是视图范围内。要解决此问题，您需要将bean放在视图范围中，并在必要时检查数据模型保留/预加载逻辑。这应该在（post）构造函数和/或（动作）侦听器方法中进行，但肯定不在getter方法中。 getter方法应仅返回数据模型，仅此而已。

如果您仍然使用JSF 1.x，它没有新的JSF 2.x视图范围，则需要在引用请求范围的托管bean的页面中添加<a4j:keepAlive>。
