esayUi中combobox用formatter渲染后无法选中下拉框

[zhjl1989]

代码如下:
<script type="text/javascript">
$(function(){
$("#deptcombobox_comboboxID").combobox({
onChange: function(newValue, oldValue){
$('#manager_comboboxID').combobox({
url:"${ctx}/sysadmin/userAction_ajaxAllUserByDept?deptId="+newValue,
valueField:"id",
textField:"name" ,
formatter: function(row){
return row.userinfo.name;
}
});
}
});

})


</script>

<input id="deptcombobox_comboboxID" class="easyui-combobox" name="dept.deptId" style="width:300px" data-options="
valueField: 'deptId',
textField: 'deptName',
url: '${ctx}/sysadmin/deptAction_ajaxAllDept'" />


<input id="manager_comboboxID" name="userinfo.manager.id" style="width:200px" />
