ext combobox赋值

[李文婷]

我从数据库取出一个对象meeting拿到修改页面上在combobox里用value显示其属性applieddepname,可是只要一写上value刷新页面就显示不出来，找来找去都不知道是哪里出了问题。。。。。。

代码如下：
var deptdata=${sdept};

var deptstore=new Ext.data.ArrayStore({
autoDestroy:true,
storeId:'dstore',
data:deptdata,
fields:[
{name:'departmentGuid',type:'string'},
{name:'departmentName',type:'string'}
]
});

var deptcomb = new Ext.form.ComboBox({
emptyText:'请选择',
fieldLabel:'*申请使用部门',
id:'applieddepname',
store:deptstore,
displayField:'departmentName',
valueField:'departmentGuid',
hiddenName:'bjxmMeeting.applieddepid',
hiddenValue:'departmentGuid',
//value:'${bjxmMeeting,applieddepname}',
typeAhead:true,
mode:'local',
triggerAction:'all',
editable:false,
autoscorll:true,
forceSelection:true,
width:150
});
