JSON load to DataView doesn't work

Any mistakes in the following code? I've been trying again and again but my JSON load doesn't work...I just see "Loading..." for several seconds then just a blank screen. I've tried loading via AJAX too, but that doesn't show the "Loading..." screen. Thanks in advance for the assistance.

Sample of my JSON data:

Code:

---

{"households":[{"HHName":"Jim Smith Household"}])

---

Code:

---

Ext.regModel('Household', {
    fields: [
        {name: 'HHName',    type: 'string'}
    ]
});

var store = Ext.create('Ext.data.Store', {
        model    : 'Household',
        proxy: {
            type: 'jsonp',
            url: 'get_households.php',
            reader: {
                type    : 'json',
                root: 'households'
            }
        },
        autoLoad: true
    });

var list = Ext.create('Ext.DataView', {
        store: store,
        itemTpl: '<p>household name is {HHName} </p>'
    });

---

Ext.regModel is not valid in ST2 and root config in the reader is now rootProperty:

Code:

---

Ext.define('Household', {
    extend : 'Ext.data.Model',

    config : {
        fields : [
            { name : 'HHName', type : 'string' }
        ]
    }
});

var store = Ext.create('Ext.data.Store', {
    model    : 'Household',
    autoLoad : true,
    proxy    : {
        type  : 'jsonp',
        url    : 'data/php.php',
        reader : {
            type        : 'json',
            rootProperty : 'households'
        }
    }
});

var list = Ext.create('Ext.dataview.DataView', {
    fullscreen : true,
    store      : store,
    itemTpl    : '<p>household name is {HHName} </p>'
});

Thanks for the reply, did not know that about ST2. I tried the new code but I'm still having an issue. I get the "Loading..." spinner for several seconds (15 or so) then a blank screen.

The PHP file is in the same directory as my custom Sencha app.js. I've tried the filename "get_households.php" as well as the full path (http://mywebsite.com/get_households.php) to no avail.

Any other ideas?

You are using JsonP so is the response valid for JsonP?

It was not, after all, I was sending just plain JSON. Thanks, I've now learned the difference between JSON and JSONP...changed the type property to 'ajax' and I'm off and running.

Thanks again for your help!
