GetData(): rows has no properties

Question

Hello,
I've got the following code:
function Update(id) {
var observer = new Object;
var rows = null;
var chat = new
Spry.Data.XMLDataSet("/xmldataset.php?liste=x&id=" + id,
"/data/field", {useCache:false});
observer.onDataChanged = function(dataSet, data) {
rows = chat.getData();
chat.addObserver(observer);
chat.loadData();
for (i = 0; i < rows.length; i++) {
document.GetElementById('xyz').innerHtml += '<span>' +
rows
['field'] + '</span><br />';
but I alway get the error:
rows has no properties (for (i = 0; i < rows.length;
i++)). What wrong? Thanks for your help

I was having problems with this and I need to add an observer
to the data set to call getData once the data is loaded. Try this:
var chat = null;
var rows = null;
function Update(id)
chat = new
Spry.Data.XMLDataSet("/xmldataset.php?liste=x&id=" + id,
"/data/field", {useCache:false});
chat.addObserver(isDataLoaded);
chat.loadData();
function isDataLoaded(notificationType, dataSet, data)
if (notificationType == 'onPostLoad')
rows = chat.getData();
showData();
else if (notificationType == 'onLoadError')
alert('Error loading data.');
function showData()
for (i=0;i<rows.length;i++)
document.GetElementById('xyz').innerHtml += '<span>' +
rows
.field + '</span><br />';
