Error Store Load - sencha-touch

Question

Good evening.
The initial view of my application need to get some data from a Store (autoLoad = true) to change some components of it. At what point can I do this?
View:
Ext.define('App.view.EmpresaPanel', {
extend: 'Ext.Container',
alias: 'widget.empresapanel',
config: {
ui: 'dark',
layout: {
type: 'card'
},
items: [
{
xtype: 'titlebar',
docked: 'top',
title: 'Menu',
layout: {
align: 'center',
type: 'hbox'
}
},
{
xtype: 'titlebar',
docked: 'bottom',
title: '2012 ©',
layout: {
align: 'center',
type: 'hbox'
}
}
]
}
});
Store:
Ext.define('App.store.Empresa', {
extend: 'Ext.data.Store',
requires: [
'App.model.Empresa'
],
config: {
autoLoad: true,
autoSync: true,
model: 'App.model.Empresa',
storeId: 'EmpresaStore',
proxy: {
type: 'ajax',
url: 'http://URL',
reader: {
type: 'json',
rootProperty: 'empresa'
}
}
}
});
Controller:
Ext.define('App.controller.Empresa', {
extend: 'Ext.app.Controller',
config: {
refs: {
empresaPanel: 'empresapanel'
},
control: {
"empresapanel": {
initialize: 'onContainerInitialize'
}
}
},
onContainerInitialize: function(component, options) {
var store = Ext.getStore("EmpresaStore"),
record = store.findRecord("id", "1");
console.log(store);
console.log(record);
}
});
First appears in console.log: Ext.apply.create.Class
In the second: null
If I put a button in this view and tap the same event I run the same code that is in the function "onContainerInitialize" the record is completed.
Is there a specific time after the creation of view where you can access data from the Store?
Thank you!

Answer 1

You should add listener for store load event to access record from the store.
Here is an example how you can do it. Put following code inside of the onContainerInitialize:
store.on('load', function(t) {
var record = t.findRecord("id", "1");
console.log(record);
}, this, {single: true});
