Access to the application instance?

[pinidbest]

Hi all,
I am building a foundation stuff in my extjs 4 application. This foundation is under a Foundation folder under my app folder and it is not part of the controller/model/data folders.
I need to access the application instance from there.
Just like this.getApplication works from the controller (I know it cant be done and why from the view)
I event tried to keep the this variable within the lunch event in a global param but this doenst work.
Is there any
Ext.app.getInstance of something like that?

Ext.application({
name : 'MyApp',

launch : function() {
MyApp.app = this;
}
});

Now you can access your app via MyApp.app
