Load Store data from Controllers and Tab Panels [ List & Map ]

Hi,
I'm trying to load Data Store into a List and a Map.

In my controller I load the data via proxy in this way:

Code:

---

action_group: function (list, record)
{
    var store = Ext.getStore("Units");       
    store.setProxy({
        type: 'jsonp',
        url: 'http://myurl.com/&var=' + record.data.name,
        reader: {
            type: 'json',
                rootProperty: 'records.units'
            }
    });
       
    store.load();

    this.getHomeView().push({
        xtype: 'group-main',
        title: record.data.name,
        data: record.data
    });
}

---

Where the xtype: 'group-main' is my Ext.tab.Panel with just 2 items:

Code:

---

items: [
{
        /* Ext.Container with a Ext.dataview.List */
}, {
        /* Ext.Container with a Ext.Map */
}]

---

Now, the List (first tab) have no problems and loads the data from the store correctly, but the map instead have no record, and I can't find the way to get what's was loaded in the controller.

Please help :)
Thanks!

How are you doing anything with the Map? And why is the list and map nested within a container?
