Extjs Model Fields with Subfields

Question

Anyone know how you model subfields of any field in ExtJS? For example

Ext.data.Model:

fields:[
   {name: 'id', type: 'int'},
   {name: 'title', type: 'string'},
   {name: 'description', type: 'string'},
   {name: 'priority', type: 'auto', fields:[
      {name: 'code', type: 'string'}
   ]},
   {name: 'createdBy', type: 'auto'},
]

then in my grid panel

Ext.grid.Panel

columns:[
    {header:'Title', dataIndex:'title', flex:1},
    {header:'Priority', dataIndex:'code'}
],

Any idea how I access the dataIndex 'code' under 'priority'? thanks in advance!

        ]
