Java 提交表单时出现JSF索引越界异常
当我在JSF表单中单击submit按钮时，会出现以下异常。它说了一个Indexout of bounds异常，但我没有使用任何与代码关联的ArrayList。这是虫子吗？我该怎么做才能消除这个错误 Mojarra:2.0.2带有primefaces 2.2的FCS JSF:2.0 NetBeans IDE 6.8 Glassfish域V3 表格编号：Java 提交表单时出现JSF索引越界异常,java,jsf-2,Java,Jsf 2,当我在JSF表单中单击submit按钮时，会出现以下异常。它说了一个Indexout of bounds异常，但我没有使用任何与代码关联的ArrayList。这是虫子吗？我该怎么做才能消除这个错误 Mojarra:2.0.2带有primefaces 2.2的FCS JSF:2.0 NetBeans IDE 6.8 Glassfish域V3 表格编号： <p:panel id="jobres" style="min-width: 200px" header="Reservation" wid

我发现这是最近发布的primefaces 2.2最终版本中的一个例子
我使用primefaces（2.2 RC2）的早期版本解决了这个异常问题。我发现这是最近发布的primefaces 2.2最终版本中的一个例外
我使用primefaces（2.2 RC2）的早期版本解决了这个异常问题。@Setu我还添加了表单代码。“你知道什么地方出了问题吗？”塞图还添加了表单代码。你知道哪里出了问题吗？Cagatay要求提供一个简单的例子来修复2.2.1。您是否有可能在仍然复制相同异常的情况下，尽可能多地切掉问题中怪物部分的不相关部分（属性/标签/组件）？我想卡加泰会非常感激的。@BalusC刚才我看到了你的评论。我真的无法将错误从整个页面中分离出来。当我试图收缩代码时，异常也消失了。Cagatay已经在primefaces论坛上得到了这个错误的示例代码，由一位绅士编写。Cagatay要求提供一个简单的示例来修复2.2.1中的问题。您是否有可能在仍然复制相同异常的情况下，尽可能多地切掉问题中怪物部分的不相关部分（属性/标签/组件）？我想卡加泰会非常感激的。@BalusC刚才我看到了你的评论。我真的无法将错误从整个页面中分离出来。当我试图收缩代码时，异常也消失了。Cagatay已经在primefaces论坛上得到了这个错误的示例代码，由一位绅士编写。
