TitlePane中嵌套TitlePane导致数据无法显示.docx

操作员维护页面Html源码如下：
<div dojoType="dijit.TitlePane" title="操作员维护"><input id="users_roles_url" type="hidden" value=""></input>
  <span></span>
  <div id="users_rolesToolBar" ></div>
  <span></span>
  <script type="dojo/method">

  function getUserName(eventObj){
  return "hppms";
  }

  function getRoleName(eventObj){
  return "admin";
  }

  function map(){
  alert("haha, i am testing...");
  dojo.connect(dojo.byId("users_roles_Users_Grid"), "onClick", getUserName);
  dojo.connect(dijit.byId("usersRoles_Roles_Tree"), "onClick", getRoleName);
  }

  dojo.addOnLoad(map);
   
  createToolBar({label: "新建角色分配", id: "users_roles_new",
  click: function(){
  clickButton({id: "usersRolesDialogNew",title: "新建角色分配",idGrid: "usersRolesGrid",url: "/rbac/users_roles",mod: "add"});
  },cls: "add", refId: "users_rolesToolBar"});

  createToolBar({label: "解除角色分配", id: "users_roles_btn_del",
  click: function(){
  clickButton({id: "usersRolesDialogDel",
  refresh: {id: "usersRolesGrid", url: '/rbac/users_roles.json'}, title: "解除角色分配",idGrid: "usersRolesGrid",url: "/rbac/users_roles",refreshUrl: "/rbac/users_roles",mod: "del"});
  },cls: "del", refId: "users_rolesToolBar"});
  </script>

通过firebug抓包发现grid、tree的json数据都获取到了，但是在firefox中显示不出来，3天了，还是没有解决，纠结哦.

没有人遇到类似情况吗？
