Load radio button/combo box data from JSON data - extjs

Question

I am trying to auto select radio button and combo box values of a form using JSON data. But, everything else (text boxes/ check boxes / data fields) is getting populated. I had no success auto selecting a value of the radio group or the combo box.
As suggested by Satya, here is the link to the jsfiddle. Clicking a row on the "movie database" populates the data in the "movie information form".

Thanks a lot in advance for help.
Here is the part of my form -
{
xtype:'radiogroup',
columns:1,
fieldLabel:'Filmed In',
name: 'filmed_in',
items:[{
name:'filmed_in',
boxLabel: 'Color',
inputValue: 'color'
},{
name:'filmed_in',
boxLabel: 'B&W',
inputValue: 'B&W'
}
]
},{
xtype: 'checkbox',
fieldLabel: 'Bad Movie',
name: 'bad_movie',
checked: true
},{
xtype: 'combo',
hiddenName: 'genre',
fieldLabel: 'Genre',
mode: 'local',
store: genres,
displayField:'url',
valueField:'name',
width: 250,
editable: false,
listeners: {select: comboSelect}
},
This is how the genres store is coded -
var genres = new Ext.data.JsonStore({
// store configs
storeId: 'genres',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'genres.data',
reader: {
type: 'json',
idProperty: 'name'
}
},
fields: ['name', 'url']
});
The url genres.data returns this -
[{"name":"1","url":"Comedy"},{"name":"2","url":"Drama"},{"name":"3","url":"Action"}]
This is the data I am trying to load into the form -
{
"id":"1",
"title":"Office Space",
"director":"Mike Judge",
"released":"02/27/1999",
"genre":"1",
"bad_movie": "1",
"filmed_in": "color",
"description": "Loved watching this ....."
}

Answer 1

For the radio button the expected value is different then your passing.
Instead of filmed_in: 'color' you'll need to pass filmed_in: { filmed_in: 'color' }.
You can override the setValue as sra mentioned so it will work with filmed_in: 'color':
setValue: function (value) {
if (!Ext.isObject(value)) {
var obj = new Object();
obj[this.name] = value;
value = obj;
}
Ext.form.RadioGroup.prototype.setValue.call(this, value);
}
For the combobox, just add name: 'genre'.
