[4.0.7] Inconsistent config of Form reader

It's not possible to define a FormPanel with a reader defined as an object.

Code:

---

var fp = Ext.create("Ext.FormPanel", {
    frame: true,
    title:'JSON Form',
    width:400,
    reader : {
        type : 'json',
        model : 'Foo',
        root : 'bar'
    }

---

This should be possible IMHO.

Opened a ticket. Thank you.

Encountering same issue - any updates on this?
