extjs - Store with autoload true should not load on application launch

Question

I have a grid linked to a store with autoLoad: true. The problem is that the store gets loaded on application launch, even if the view is created only later when ac

This is my final controller code:

Ext.define('Mb.controller.Winbiz', {
    extend: 'Ext.app.Controller',
    views: [
        'Owners'
    ],
    refs: [{ref: 'testGrid', selector: 'test-gridPanel'}],
    init: function(){
        this.listen({
            store: {
                '#Owners':{ load: this.onOwnersLoad}
            }
        })
        this.control({
            'menu #test': {click: this.onMenuTest},
            'test-gridPanel': {render: this.onOwnersRender}
        })
    },
    onMenuTest: function(){
        this.getController('Main').addToMainTab('test-gridPanel');
    },
    onOwnersLoad: function(store){
        store.loaded = true
    },
    onOwnersRender: function(){
        var store = this.getTestGrid().getStore();
        if(!store.loaded)store.load();
    },

It puts all code into the controller as suggested by @pcguru and uses the render event to shorten the code as suggested by @Lolo. Thanks

I would let the view's controller handle the store load.

Start by disabling autoload on the store.

Ext.define('Mb.controller.Winbiz', {
    extend: 'Ext.app.Controller',
    views: [
        'Owners'
    ],
    ownerStore: null,
    init: function(){
        this.control({
            'menu #test': {click: this.onMenuTest},
        });

        this.ownerStore = Ext.getStore('winbiz.Owners');
    },
    onMenuTest: function() {
        if (this.ownerStore.loaded === false) {
            this.ownerStore.load(
                scope: this,
                callback: this.onOwnerStoreLoaded
            );
        }
        else {
            this.addToTab();
        }            
    },
    onOwnerStoreLoaded: function (store, records, successful, eOpts) {
        if (successful) {
            store.loaded = true;
            this.addToTab();
        }
    },
    addToTab: function () {
        this.getController('Main').addToMainTab('test-gridPanel');
    }

Wheter you want to change the view before or after the store is loaded is another question.

You can add render handler to view which will call store load method and disable autoLoad.

Example listener:

Ext.define('Mb.view.winbiz.Owners', {
    extend: 'Ext.grid.Panel',
    [...],

    initComponent: function(){
        this.callParent();
        this.on('render', this.loadStore, this);
    },

    loadStore: function() {
        this.getStore().load();
    }
});
