我正在使用rich：ModalPanel来插入一些用户，但我的commandButton中的操作似乎没有响应。
<rich:modalPanel id="panel" moveable="true" top="150" width="400" autosized="true">
<h:form id="uploadForm">
<a4j:outputPanel id="uploadOutputPanel">
<h:panelGrid id="uploadPanelGridId" columns="2">
<h:inputText value="#{adminModele.checkerNumber}"/>
<a4j:commandButton value="save"
action="#{OperationController.add}"
oncomplete="if (#{facesContext.maximumSeverity==null}){#{rich:component('LogAddDownloadPanel')}.hide();}"/>
<h:outputText value="Uploaded File Name : #{adminModele.checkerNumber}"/>
</h:panelGrid>
</a4j:outputPanel>
</h:form>
</rich:modalPanel>

通常您使用其名称访问bean，但首字母是“小写”：
（适用于@extends('layouts.app')
@section('css')
@parent

@stop
@section('content')

@stop
，@Named或隐含添加@ManagedBean等范围。
@RequestScoped你明确地将豆子命名为那个，或者你的意思是：
action="#{OperationController.add}"
（来自你的action="#{operationController.add}"
我会假设后者......）
请注意，此表达式区分大小写，但您应收到有关此内容的错误/警告：“无法解析变量名称”或类似？
ps。：如果至少前两个字母为大写字母，则不适用
...为了支持偶尔使用所有大写名称，我们检查是否 名称的前两个字符都是大写的，如果是的话 不要管它。因此，例如，“FooBah”变成“fooBah”“Z”变为 “z”“URL”变为“URL”我们提供方法Introspector.decapitalize 它实现了这个转换规则。
因此，名为adminModele的Bean不会被URLController访问，而是以其原始名称访问。
