Failed loading 'app/view/Viewport.js', please verify that the file exists

Trying to get MVC to work and you're getting "Failed loading 'app/view/Viewport.js', please verify that the file exists" as an error? The solution: add the following line to your Ext.application config;

autoCreateViewport: false,

its that simple!

So now a basic config for an Ext.application should look like;

Ext.application({
    name: 'AM',
    autoCreateViewport: false,
    appFolder: 'app',

    launch: function() {
        Ext.create('Ext.container.Viewport', {
            layout: 'fit',
            items: [
                {
                    xtype: 'panel',
                    title: 'Users',
                    html : 'List of users will go here'
                }
            ]
        });
    }
});

For more information on the MVC in Extjs4 look no further than the official guide http://docs.sencha.com/ext-js/4-0/#/guide/application_architecture

I tried using the  javax.persistence.jar from J2EE / Glassfish modules but this didn't fix it for me, so I just had the methods with errors return null ). 3. Import the examples Select the src folder in your project (eclipse), select "file import" navigate to the examples-src folder inside the gxt 3 download and se...
