ExtJS 4 MVC multiple instances of views and sub/child controller difficulties

Question

I have encountered a problem with the MVC pattern in ExtJS 4. At least, I think I have. Having approached multiple people with this question, and having posted numerous times in

How do you create your views? I see no reason why you cannot pass a different store or config data to every object. Some code samples would help for what exactly you are doing. For example, we have a similar sounding application, and everything is done with extensions. So, if we need a grid, we run

Ext.define('MyApp.grids.something',{
extends:'Ext.grid.panel' 
//...

These classes are predefined. Then, when a controller or view is loading this grid, they are using

var grid=Ext.create('MyApp.grids.something',{id:'unique',store:mystore});

As you can see, we can pass in different config options to the same grid each time it is created. We can treat this exactly as you would treat

Ext.create('Ext.grid.Panel');

Except of course that we make some options predefined, and some non-override-able, and so on.

Hope this helped.
