Try to require every ST element that you use in your app.
* Note that the requires must be out of the "launch" function.
Code:
Code:Ext.application({
name:'MyApp',
models:['User','Group'],
stores:['Users'],
controllers:['Users'],
views:['Main','ShowUser'],
requires: [
'MyApp.view.LogoImage',
'MyApp.view.LinkButton',
'Ext.form.Panel',
'Ext.field.Text',
'Ext.field.Password',
'Ext.Button',
'Ext.Img',
'Ext.Label'
],
launch:function(){Ext.create('MyApp.view.Main');}
});
Cheers!
