Extjs 4 how to return xml data with additional information from server to extjs controller?

Question

I hope someone helps me out.

I want to load my grid with xml file's data, locally. I created model,store and grid. I load the store in render event of grid.

The problem is, Store is loaded but the grid is still empty. I looked at the grid at console, and grids items contains the loaded data, but grid doesnt contain the data on the screen.

Here is the model

Ext.define('BTOM.model.test.test', {
    extend: 'Ext.data.Model',
    fields: [
        { name: 'id', type: 'string' },
        { name: 'name', type: 'string' },
        { name: 'phone', type: 'string' }
    ]
});

Here is the store

Ext.define('BTOM.store.test.test', {
    extend: 'Ext.data.Store',
    model: 'BTOM.model.test.test',
    autoLoad: false,

    proxy: {
        type: 'memory',
        reader: {
            type: 'xml',
            root: 'users',
            record: 'user'
        }
    }
});

And the grid

Ext.define('BTOM.view.test.test', {
    extend: 'Ext.grid.Panel',
    store: 'BTOM.store.test.test',
    alias: 'widget.test',
    title: 'Test',

    initComponent: function () {

        this.columns =
        [
            { header: "Id", width: 120, dataIndex: 'id', sortable: false },
            { header: "Name", width: 180, dataIndex: 'name', sortable: false },
            { header: "Phone", width: 115, dataIndex: 'phone', sortable: false}
        ];

        this.callParent(arguments);
    },
});

And where I load the store is

render: function (grid, eOpts) {
    var store = grid.getStore();
    var data =
        '<?xml version="1.0" encoding="utf-8"?>' +
           '<users> ' +
              '<user><id>1</id><name>Bll QASD</name><phone>333 2211</phone></user> ' +
              '<user><id>2</id><name>Asd QWF</name><phone>444 2211</phone></user> ' +
              '<user><id>3</id><name>Zas QWE</name><phone>555 2211</phone></user> ' +
           '</users>';
        var dataXml = (new DOMParser()).parseFromString(data, 'text/xml');
    console.log(dataXml);
    store.loadRawData(dataXml, true);
    console.log(grid);

}

dataXML document is created without problem. grid seems to contain the data (by firebug, I can see) but datagrid is empty, doesnt show the data!

Ok, the error is that you are defining the store but not creating it. So the grid just has the name of the store but it expects a store instance, or is that some thing you have missed in the code snippet above. I used the same code and here is a running example: https://fiddle.sencha.com/#fiddle/oel
