推荐答案

首先，删除＆LT; H：形式prependId =假＆GT; 。这是一个与阿贾克斯不兼容。不要忘了，现在给的形式固定ID。

First of all, remove <h:form prependId="false">. It's incompatible with ajax. Don't forget to give the form a fixed ID now.

<h:form id="formId" styleClass="form">

其次，过程属性是你的情况不对，你正在使用的EL EX pression与组件的cliend ID作为EL范围内的变量。这是不作任何意义。只要是一个正常的字符串。

Secondly, the process attribute is in your case wrong, you were using an EL expression with the component's cliend ID as a variable in the EL scope. This isn't making any sense. Just make it a normal string.

引用正确的客户端ID的规则可以在以下答案中找到：<一href="http://stackoverflow.com/questions/8634156/how-to-reference-components-in-jsf-ajax-cannot-find-component-with-identifier/8644762#8644762">How引用组件的JSF AJAX？无法找到标识符QUOT组成部分;富＆QUOT;鉴于。应用了，它应该是这个样子（注意： preFIX）：

The rules of referencing the proper client ID can be found in the following answer: How to reference components in JSF ajax? Cannot find component with identifier "foo" in view. Applying that, it should look something like this (note the : prefix):

process=":formId:scenarioTabViewId:isApprovedBooleanId_checkBox"

另一种方法是物理CheckBox组件绑定到，像这样的观点：

An alternative would be to bind the physical checkbox component to the view like so:

<p:selectBooleanCheckbox binding="#{checkbox}" ... />

，然后引用它的客户端ID与的 UIComponent＃getClientId（） 像这样（也是在这里，请注意： preFIX）：

And then reference its client ID with help of UIComponent#getClientId() like so (also here, note the : prefix):

process=":#{checkbox.clientId}"
