V2 - When is AW.XML.Table response object filled?

Hi,
I'm using the code below to get XML data from a URI. Is there a convenient
way of finding out when the asynchronous request has completed?

myModel = new AW.XML.Table();
myModel.setRows(rowsXPath);
myModel.setURL(dataURI);
myModel.request();

Many thanks,
BT

I am trying to do this as well. Has anyone found a way?

var request = new Active.HTTP.Request;
         request.setURL("http://www.activewidgets.com/messages/all.rss");
         request.setAsync(true);
         request.response = function(doc) {
            alert(doc);
         }
