multiple instances of store in controller

hi experts

I am trying to instantiate a grid component in my accordion

In my controller i am doing

Ext.each(Items, function(Item, index) {

Ext.Ajax.request({

loadMask : true,

url : 'getByNew.controller',

method : 'GET',

params: {

Id: Id,

},

scope : this,

success : function(response, callOptions) {

var Data = Ext.decode(response.responseText);

accordian.add({

titleata.id

items: [

{

layout: {

type: 'hbox',

pack : 'center'

},

items:[{

initComponent : function(){

debugger;

var me = this;

var tpainStore = Ext.create('TPAIN.store.MyStore');

Ext.apply(me,{

store: tpainStore

});

me.callParent(arguments);

},

xtype: 'grid',

id : 'tod'+index,

alias: 'widget.tod'+index,

title: 'Product',

height : 400,

width : 420,

stripeRows : true,

columnLines: true,

//store:

margin : '3 3 3 3',

columns: [

{header: 'Product', dataIndex: 'product', flex: 1,sortable:true,hideable:false}

]

}

In my initComponent i am trying to instatiate store each time and it doesnt work ,

When i run the app i get error : Uncaught TypeError: Cannot read property 'items' of undefined

If i remove the initComponent function it works fine.

Any idea how i can do this?

Any help will be appreciated

Thanks

Jay
