View Full Version : Ext.Loader is undefined

29 May 2017, 1:03 AM

I'm just new with Sencha and I try to follow the CarListing tutorial (http://docs.sencha.com/architect/4/guides/tutorials/first_desktop_application.html).
My SenchaCmd is under C:\Dev\Workspace\SenchaArchitect\SenchaCmd\
My CarListing project is under C:\Dev\Workspace\SenchaArchitect\CarListings

I've performed the sencha web start with a map to the CarListing project.
When I run http://localhost:1841/carListing/index.htmI I get a blank window and the error Ext.Loader is undefined in app.js:17:0.

Here is the app.js auto generated (I don't have touched it) :

launch: function() {
Ext.create('CarListings.view.CarListings', {renderTo: Ext.getBody()});


Can someone give me an hint on how about to resolve this?

You've posted in the Ext JS 3.x forum. Which specific versions of Ext JS, Architect and Cmd are you using?

I'm using :
- Sencha Architect 3.5.1
- Cmd
- ExtJS 6.0.x

Architect is parameted to store :
- Frameworks in C:\Dev\Workspace\SenchaArchitect\Frameworks
- Components in C:\Dev\Workspace\SenchaArchitect\Components
- Extensions in C:\Dev\Workspace\SenchaArchitect\Extensions
- Templates in C:\Dev\Workspace\SenchaArchitect\Templates

Architect is parameted to use custom Cmd in C:\Dev\Workspace\SenchaArchitect\SenchaCmd (

I've just tested to create a new project based on the exemple Car Listings under C:\Dev\Workspace\SenchaArchitect\CarListing2

I've launched sencha web start -map carListing2=C:\Dev\Workspace\SenchaArchitect\CarListing2
When I launch http://localhost:1841/carListing2, I get the Ext.Loader is undefined

Is there anything that I've done wrong?
