Code:



Ext.define('MyApp.model.Person', {
    extend: 'Ext.data.Model',
    fields: [
        {
            name: 'first',
            type: 'string',
            mapping: 'firstName'
        }        
    ]
});


var record = Ext.create('MyApp.model.Person', {firstName: "Jackie"});


if(record.get('first') === '') {
        Ext.Msg.alert('Oh No!', 'Who am I?');    
}

I'm getting a blank when I execute record.get('first');
