Ext JS 4: Unable to display the date from record in the 'datefield' - extjs4.1

Question

I am trying to load the record in the form. One of the field type is 'datefield' and have a field in record in milliseconds.
parital record data:
topAccount:"ALPINE"
tradeDate:1360167174553
tradeId:"2110720401"
and the view is
xtype: 'datefield',
name: 'tradeDate',
itemId: 'tradeDate',
margin: 8,
fieldLabel: 'Trade Date:',
renderer: Ext.util.Format.dateRenderer('Y/m/d'),
But, when the form is loaded with record, I get empty field.
Can someone help me on this problem?
Thanks

1360167174553 is not a valid date for this purpose. 1920-12-01T13:00 is.
If you look at the Date datatype, you'll see:
DATE: {
convert: function(v) {
var df = this.dateReadFormat || this.dateFormat,
parsed;
if (!v) {
return null;
}
if (Ext.isDate(v)) {
return v;
}
if (df) {
return Ext.Date.parse(v, df);
}
parsed = Date.parse(v);
return parsed ? new Date(parsed) : null;
},
sortType: st.asDate,
type: 'date'
}
});
With a number, Ext.isDate() will fail. Then both Ext.Date.parse and Date.parse expect a string, the tokens of which do not support just milliseconds.
If you insist using milliseconds try this:
Ext.define('YourModel', {
extend: 'Ext.data.Model',
fields: [
{name: 'tradeDate', dateFormat: 'u' }
]
});
