            "type": "FeatureCollection",
            "features": [
                {
                "properties": {
                               "graphic": "img/restaurant.png",

                    rootProperty: 'features'
                }

    Hi hauos,

    Add fields config into the Features model.

    Code:
    
    Ext.regModel('Features', 
    {
            fields:['features'],
            hasMany: {model: 'Properties', name: 'properties'}
        }); 
       Ext.regModel('Properties', 
    { 
           fields: ['graphic', 'Name', 'Country', 'City'],
            associations: [
                {type: 'belongsTo', model: 'Features'}
            ] 
       });
