This is an example of app where stores do not autoload....

I added this to an index.js to show how "creating" the stores will then autoload...
Code:
        // need to create the stores so they exist in the store manager before init
        Ext.create('BenAdmin.store.StoreVisit');
        Ext.create('BenAdmin.store.StoreVisitsSites');
        Ext.create('BenAdmin.store.StoreVisitsStats');
        Ext.create('BenAdmin.store.StoreVisitsList');
This can be seen here....
