ext 下拉框问题

Question

[code="java"]
var dayStore = new Ext.data.SimpleStore({
fields:['days','post1'],
data:[['01','01'],['02','02'],['03','03'],['04','04']]
})
[/code]
[code="java"]
{
fieldLabel:'月结账日',
xtype:'combo',
id:'thisDay',
hiddenName:'Qdeptid',
store:dayStore,
displayField:'days',
valueField:'post1',
forceSelection:true,
selectOnFocus:true,
editable:false,
triggerAction:'all',
model:'local',
value:new Date().format("Y-m-d").substring(8,10)+"日"

            }

[/code]

为啥这个固定的下拉框显示不出来？报的错误如图：

Answer 1

model:'local'
写错了！！！
应该是mode:'local'
