请教关于extjs与struts2互相传递数据问题!

[RockPlus]

各位好。我的项目前台用的是extjs,后台是struts2+Spring+mybatis。我在界面上有个查询按钮,一点查询会将条件传递给后台，后台根据条件从数据库中找到相应的数据，并返回给前台。
下边是我的form

function LoadForm(baseUrl)
   { 	
    	   var fpProductSearch = new Ext.FormPanel({
    	   renderTo: 'searchDiv',
    	   id:"fpProductSearch",
           labelWidth: 75,
           frame:true,
           title: '产品搜索',
           bodyStyle:'padding:5px 5px 0',
           width: 350,
           defaults: {width: 230},
           defaultType: 'textfield',

           items: [{
                   fieldLabel: '产品名称',
                   emptyText:'B-5538(YAS023400)',
                   name: 'product.productname'
               }],
           buttons: [{
           	id:"btnSearch",
               text: '查找',
               handler: function(){
   			var baseParams = fpProductSearch.form.getValues();
   			fpProduct.getForm().reset();
   		    Ext.Ajax.request({
   				url : baseUrl + '/productAction!SearchProduct',
   				method:"post",
   			 	params: baseParams,
                   success: function (response,options) {
                	   obj = Ext.decode(response.responseText);
                       if(obj.success)
                    	   {
                    	   fpProduct.getForm().setValues(obj.message);
                    	   }else
                    		   {
                    		   		Ext.Msg.alert('错误', obj.message); 
                    		   }
   					},
			   		 failure: function(response,options) {   
			             Ext.Msg.alert('错误', response.statusText);   
			       }
   		    
   		    });
   			
               }
           },{
           	id:"btnSReset",
               text: '清空',
               handler: function(){
                   fpProductSearch.getForm().reset();
               }
           }]
       });

               }
           }]
       });
   }

我绑定的是候，用的是name: 'productname',这个字段，现在的问题，后台返回的数据，我的前台能显示出来，但是当我点击提交按钮的进候，后台接收不到前台发过去的数据？我用抓包工单看了一下，发现这样提交的过去的数据是不含类名的，也就是productname='abc'，我看了别人的代码，将extjs的字段写这样name: 'product.productname',后台就可以收到数据了，但是前台因为加了一个类名,后台发送的过来的数据就显示不出来了。我前台是这样赋值的:fpProduct.getForm().setValues(obj.message); 请问有谁知道这种情况怎么处理啊？谢谢了。
下边是后台action

你可以把值这样赋给带类名的参数
var formData = Ext.util.JSON.decode(form.responseText);
fpanel.getCmpByName("questionReportDetail.questionAnalysis").setValue(this.questionAnalysis);
fpanel.getCmpByName("questionReportDetail.modifyAdvice").setValue(this.modifyAdvice);

你在FIREFOX中的firebug中看看提交的参数是什么，和ACTION中的参数是不是一致
