--------------------------------------
i want to this code but..

Code:

---

Ext.define('MyView1',{
 extend: Ext.grid.Panel,

store: 'MyStore1'
}

---

but not working.

both Im using

Code:

---

function addController(controller){
  controller.init(); // MyViewController1
}

---

How is MyStore1 defined?

FYI: The first approach is not correct. You should call create inside initComponent

Scott.

Code:

---

Ext.define('MyStore1',{
 extend: 'Ext.data.Store',
 proxy:{
}
}

---

that code are my not real code just for example same structure.

I writing WebApp.

Web App have user permission and has many component.

I called once Login.js controller. Because user permission. I'm use addController function.

store: 'MyStore1' is not working.
store: Ext.create('MyStore1') is worked.
