请教 Coolite Treepanel 和 Tabpanel的使用

当我从webservice上给node的href属性赋值后 在前台点击节点 增加新tab页载入页面时格式不对 具体代码 如下服务：public TreeNodeCollection GetNode(string upid)
    {
        TreeNodeCollection GNodes = new TreeNodeCollection(false);
        dv.RowFilter = "upmoduleid=" + upid;
        Coolite.Ext.Web.TreeNode tempNode;
        foreach (DataRowView dr in dv)
        {
            tempNode = new Coolite.Ext.Web.TreeNode();
            tempNode.Text = (string)dr["ModuleName"];
            tempNode.NodeID = dr["ModuleID"].ToString();
            //tempNode.Href = dr["ModuleURL"].ToString();
            tempNode.Leaf = (bool)dr["IsLeaf"];
            //nodes.Add(tempNode.Nodes);            System.Data.DataView dvs = new System.Data.DataView();
            string sqls = "select * from RGP_Modules where upmoduleid= " + dr["ModuleID"];
            DataSet dss = new DataSet();
            dss = JM_RDateTable(sqls);
            dvs.Table = dss.Tables[0];
            Coolite.Ext.Web.TreeNode ChildNodes;
            foreach (DataRowView drs in dvs)
            {
                ChildNodes = new TreeNode();
                ChildNodes.Text = (string)drs["modulename"];
                ChildNodes.NodeID = drs["moduleid"].ToString();
                //ChildNodes.Href = drs["ModuleURL"].ToString();                ChildNodes.Leaf = (bool)drs["isleaf"];
                
                tempNode.Nodes.Add(ChildNodes);
            }
            GNodes.Add(tempNode);
        }
        return GNodes;    }
红色为赋值url
前台：function CreatTab(tabPanel,node) {
             var tab = tabPanel.getComponent(node.id); 
             if(node.leaf){
                 if(tab){
                   tabPanel.remove(tab); 
                 }
                    tab = tabPanel.add({ 
                        id: node.id, 
                        title: node.text, 
                        closable:true,
                        autoLoad:{
                            showMask: true,
                            url:node.attributes.href,                            mode:"iframe",
                            maskMsg: 'Loading ' + node.text + '...'
                        }                   
                          
                    }); 
               
                tabPanel.setActiveTab(tab);
            }
 }
当我不在webservice中赋值url  结果就是对的  请高手赐教
