How to reuse store in MVC application without multiple reloads?

Question

JavaScript

Good afternoon.
I am writing an MVC application on extjs4.

Unlike the examples on the sencha site, I have a situation where one Store is used several times (for example, on one tab in a combobox, on another in a grid).

Application launches a Viewport that contains a tabpanel.
Each tab has its own controller and many views.

My problem: Store is loaded many times - every time it is mentioned in the controller.
Store configured with autoload: true .
Proxy configured in Model.

If I remove Store from the [stores] array of the taba controller, the combobox will be empty, although it says store:Ext.getStore('STORE-ID') Tell me

in which direction to dig, or an example with reusing Store and not Model

Answer 1

remove autoload: true and call Ext.getStore('STORE-ID').load() once, on initialization, for example

Answer 2

Go through the code with the debugger, perhaps in the place where you use getStore('.. ...') it is not yet initialized and cannot be referred to by its name.
and about the question: "How to reuse store" well, I use grid.reconfigure(store,columns) - if the columns in the grid change and then just force store.load
