        ]
        });

// extra extra simple
new Ext.Panel({
    title: 'ExtJS.com Visits Trend, 2007/2008 (No styling)',
    renderTo: 'container',
    width:500,
    height:300,
    layout:'fit',
    items: {
        xtype: 'linechart',
        store: store,
        xField: 'name',
        yField: 'visits',
        listeners: {
            itemclick: function(o){
                var rec = store.getAt(o.index);
                Ext.example.msg('Item Selected', 'You chose {0}.', rec.get('name'));
            }
        }
    }
});
});

</script>
<body style="padding: 50px;"><div id='container'></div></body>
 </html>

No network problem, all needed ressources are correctly loaded .. also tried with no def of the url, in this case extjs get the swf on yahooui cdn, same problem

回答1:

you cannot run it locally without a webserver, that's why it fails. Setup up a local webserver an it should work.
