[Gundul]

This is the code create by the Architect 2.1.0
Panel:

Ext.define('MyApp.view.MyPanel', {
    extend: 'Ext.panel.Panel',

    frame: true,
    height: 443,
    width: 614,
    layout: {
        align: 'stretch',
        type: 'vbox'
    },
    title: 'My Panel',

    initComponent: function() {
        var me = this;

        Ext.applyIf(me, {
            items: [
                {
                    xtype: 'gridpanel',
                    autoShow: false,
                    height: 245,
                    stateId: 'Grid',
                    title: 'My Grid Panel',
                    store: 'MyXmlStore',
                    viewConfig: {
                        frame: true
                    },
                    columns: [
                        {

The XML is at the url: localhost/Auto.xml
Someone can say me where are the errors?
I'm trying to learn this language but is so difficult as the beginning...
sorry for my english

There were 4 duplicates of the same post. I've consolidated it into this one thread and approved it (it was in moderation).

What happens? Are there any errors? Are you hosting it on localhost? Does the grid show up without the data?

[Gundul]

In the architect i can see all the data but when i launch the page it show only the grid without data... sorry for the duplicates but when i reload the page it didn't show the new thread and i thought it has not been send

[aconran]

Is your Store added to the stores configuration on Application?

[Gundul]

If you mean in Ext.app.Controller the MyXmlStore is already add

[aconran]

If you execute
Ext.getCmp('MyXmlStore').getRange()

on the console do you see records returned?

Did you see it make a request?

[Gundul]

It retourn that there is a syntax error

[aconran]

Sounds like your store is not even being defined then.

Are you loading the controller that your store has been associated to?

[Gundul]

Controller?

If it help in this .zip there is the program and the XML
