我有以下JSF代码（为了理智而剥离）：

目标是当单击selectBooleanCheckbox时，将相应地启用/禁用|必需/不需要密码字段。当a4j：support中的onclick事件触发时，我遇到以下异常：

当我删除a4j：support时，不再抛出异常，但当然密码字段没有更新...我也尝试删除ajaxSingle属性，这也导致异常不再被抛出，但是同样，密码字段不会相应地重新生成。我试过重新渲染整个表单，dataTable，panelGrids等无济于事。我甚至试图将inputSecret包装在a4j：outputPanel中以找不到差异。

我一直在打扰自己几天，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期间抛出异常的例子，但是该错误与rowIndex无关）。任何建议都会受到高度赞赏，因为我的死线越来越近了，我不知所措。如果这对我来说是愚蠢的，请务必告诉我。

Answer 1

我终于想出了这个问题。答案是包装＆lt; h：inputSecret /＆gt;在

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

然后设置ajaxSingle =＆＃34; false＆＃34;在＆lt; a4j：support /＆gt;

中

花了一段时间来弄明白，但最后，最后看了一下RichFaces文档，找到了答案。

a4j：支持reRender导致抛出NumberFormatException
