问题使用Spring WebFlow 2绑定对象列表和属性

Question

我很难将复选框的值绑定到在回发期间嵌套在List中的对象。 Webflow和列表中的嵌套对象是否存在问题？

JSP

<div style="margin-left: 15px; margin-bottom: 8px;">
              <form:checkbox id="firmUserBeingEditedPermissionList[${status.index}].cascading" path="firmUserBeingEditedPermissionList[${status.index}].cascading" 
                onclick="toggleCascading(${status.index}, this, event);"/><spring:message code="setFirmPermissions.cascading" />
            </div>

flow.xml

<input name="userName" required="true"/>

<on-start>
    <evaluate expression="firmUserPermissionDetailViewBuilder.createFirmUserPermissionDetailView(userName)" result="flowScope.firmUserPermissionView" />
</on-start>

<view-state id="setFirmPermissions" view="admin/setFirmPermissions3" model="firmUserPermissionView">
   <binder>
       <binding property="firmUserBeingEditedPermissionList" required="true"/>

   </binder>
   <transition on="submitAddFirm" to="setFirms">
   </transition>
   <transition on="submitPermissions" to="viewAndConfirm"/>
   <transition on="cancelSetFirmPermissions" to="cancelChange"/>
</view-state>

firmUserPermissionView

公共类FirmUserPermissionView实现Serializable {

private static final long serialVersionUID = -7219027256643534729L;

public static final String KEY = "firmUserPermissionView";

private AbstractUser currentAdminUser;  
private AbstractUser firmUser;
private List<UserPermissionFirmDetail> firmUsersCurrentUserPermissionDetailList;
private List<UserPermissionFirmDetailFBO> firmUserBeingEditedPermissionList;

public List<UserPermissionFirmDetail> getFirmUsersCurrentUserPermissionDetailList() {
    return firmUsersCurrentUserPermissionDetailList;
}

public void setFirmUsersCurrentUserPermissionDetailList(
        List<UserPermissionFirmDetail> firmUsersCurrentUserPermissionDetailList) {
    this.firmUsersCurrentUserPermissionDetailList = firmUsersCurrentUserPermissionDetailList;
}

的servlet

<bean id="flowController" class="org.springframework.webflow.mvc.servlet.FlowController">
       <property name="flowExecutor" ref="flowExecutor"/>
</bean>

<flow:flow-executor id="flowExecutor" flow-registry="flowRegistry"/>

<!-- This creates an XmlFlowRegistryFactory bean -->
<flow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices">
       <flow:flow-location path="/WEB-INF/flows/setFirmPermissions.xml"/>
</flow:flow-registry>

<flow:flow-builder-services id="flowBuilderServices" view-factory-creator="viewFactoryCreator" development="true"/>

<bean id="viewFactoryCreator"   class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
  <property name="useSpringBeanBinding" value="true"/>
  <property name="viewResolvers">

                  <ref bean="viewResolver"/>
          </list>
  </property>

UserPermissionFirmDetailFBO扩展UserPermissionFirm
