EasyUI ComboGrid组件，分页、多选回显的时候无法选中

描述：

          因为combogrid据表格下拉框结合了可编辑文本框控件和下拉数据表格面板控件，该控件允许用户快速查找和选择,并且带有分页，当选中的数据在第二页的时候，初始化加载会出现无法选中的情况 
解决思路：

         把选中的数据，在修改页面加载的时候尽量放在第一页

前台：

$('#custId').combogrid({
					url:"${g.createLinkTo(dir:'businessDpartment',file:'getdata')}?pdata=${result.custId}",
					height:28,
					panelWidth: 480,
					panelHeight:400,
					editable:false,
					pageSize:1000,
					idField: 'cust_id',
					textField: 'ch_name',
					required:true,
					multiple:true,
					pagination:true,
					editable:false,
					fitColumns:true,
					toolbar:"
客户编号/名称：  
",
					columns:[[
						{field:'cust_no',title:"客户编号",width:120,align:"center",sortable:false},
						{field:'ch_name',title:"客户中文名",width:120,align:"center",sortable:false},
					]],
					onLoadSuccess:function(data){
						var map={};
						var res0="${result.custId}";
						var res1= res0.split(",");
						console.log(res1);
						console.log(res0);
						$("#custId").combogrid('setValues',res1)
					}
				});
