Instance store variable for class extending Combobox

[UbuntuPenguin]

Hello Everyone,
I have a Combobox that I am going to use for "Live Search". I would rather not have a globally available store for the combobox but I would like to have an instance variable for the combobox. My question is, what is the best way to create an instance store in a class that extends Combobox. As of now I am going with something like this until told otherwise.




initComponent:function () {
var me = this;
var localStore = Ext.create();


Ext.applyIf(me, {
store: localStore,
displayField: 'title',


Any help is greatly appreciated.

See if this works:


Ext.define('myStore', {
extend: 'Ext.data.Store',
alias: 'store.mystore'
//.... the rest of the store config ....
});

Ext.define('myCombo', {
requires: ['myStore'],
initComponent: function () {
this.store = {
type: 'mystore'
//... any additional component specific store configs
}
// .... the rest of your initComponent code
}
});

You could change to:

store: Ext.create()
or
me.store = localStore

I was thinking that the create method didn't create unique instances after reading skirtle's blog article:

The difference is the initComponent section that allows you to create in factory mode as well.

Right on. Wasn't aware of that distinction. And that's why I browse the forums!

Thx for the tip.

Thanks slemmon, I'll try that when I get home tonight. And just to be sure, the 'myStore' is declared in the same class file as the combobox correct ?

And to Scott, do you mind explaining what you mean by 'Factory' mode. I know what a Factory is, but I'm not sure of the implications in this context when referring to the creation of components.
