Ext.Updater: Extjs3.4 migration to extjs 4.1

Hello,

In my version ExtJs3.4, I use Ext.Updater with:

Code:

---

    Ext.Updater.defaults.showLoadIndicator = false;
    Ext.Updater.defaults.loadScripts = true;

    var mgr = new Ext.Updater (myComponent)
    mgr.formUpdate (formid, url, .., ..);

---

My question is how can I migrate it into ExtJs4.1?

I can not choose the form to post with Ext.ComponentLoader
