A4J：支持重新解析导致NumberFormatException异常被抛出

我有以下的JSF代码（剥离下来理智的缘故）：A4J：支持重新解析导致NumberFormatException异常被抛出

当我删除了A4J：支持，异常不再抛出，当然密码字段不更新...我也尝试删除ajaxSingle属性，这也导致异常不再被抛出，但是，再次，密码字段不会相应reRendered。我试图重新渲染整个窗体，dataTable，panelGrids等无济于事。我甚至试图将inputSecret包装在a4j：outputPanel中以查找没有区别。

我一直在殴打自己了好几天，到目前为止，我发现NumberFormatException和强大的Google上的reRender尝试之间没有关联（我发现在reRender中抛出异常的例子，但错误与rowIndex无关）。任何建议将不胜感激，因为我的死线越来越吱吱作响，而且我不知所措。如果这对我来说太愚蠢了，一定要让我知道。

尝试将id =标记添加到您的控件，以便更容易找出j_id242是什么。同时发布你的java代码可能会有所帮助，ldapUser和ldapStr是什么类型？ – arved 2012-02-21 11:42:29

我还没有找到j_id组件所属的组件。我在inputSecret周围的所有内容中都添加了id属性，但没有找到它。 ldapUser是一个布尔值，ldapStr是一个字符串。 – 2012-02-21 19:17:27

我终于想出了这个问题。答案是包裹< H：inputSecret/>在

<a4j:outputPanel layout="none" ajaxRendered="false"> </a4j:outputPanel>

，然后在< A4J设置ajaxSingle =“假”：支持/ >

过了一段时间来弄明白，但最后，最后看了一下RichFaces文档，发现了答案。
