Region.addObserver Problem with PHP Files

Question

Hi,
I try to load a Dynamic XML via PHP Files.
everything works fine. but when i use a Region.addObserver
the callback function dont trigger.
It only happen with php Files.
My code is
quote:
<script language="JavaScript" type="text/javascript"
src="{{server}}/includes/xpath.js"></script>
<script language="JavaScript" type="text/javascript"
src="{{server}}/includes/SpryData.js"></script>
<script language="JavaScript" type="text/javascript">
var lastSharing = new
Spry.Data.XMLDataSet("{{server}}/lastSharing.xml", "lastSharing");
var categories = new
Spry.Data.XMLDataSet("{{server}}/getCategories.php?user={{user}}",
"categories/category");
var tags = new
Spry.Data.XMLDataSet("{{server}}/getTags.php?user={{user}}",
"tags/tag");
var posts = new
Spry.Data.XMLDataSet("{{server}}/getLastUserPosts.php?user={{user}}",
"data/fav");
function onComplete(notificationType, notifier, data)
if (notificationType == "onPostUpdate")
div = document.getElementById(data['regionID'])
div.style.visibility = "visible";
Spry.Data.Region.addObserver("usertags", onComplete);
Spry.Data.Region.addObserver("links", onComplete);
Spry.Data.Region.addObserver("links2", onComplete);
Spry.Data.Region.addObserver("posts", onComplete);
</script>
{{server}} and {{user}) obvious are fake. here the callback
function is trigger when the file
var lastSharing = new
Spry.Data.XMLDataSet("{{server}}/lastSharing.xml", "lastSharing");
is loaded but nothing happens with the other, the 4 DIVS
exist.
in the php file i use something like that:
quote:
private function doXml($data)
header('Content-Type: text/xml');
echo "<categories>\n";
foreach($data as $catego)
echo
"<category><![CDATA[".$catego['nombre']."]]></category>\n";
echo "</categories>\n";
Any idea??
thanks.

That is really strange that it works when things are flat XML
files and not in the case where it's PHP, the code paths are the
same, and the Spry code is unaware of the source of the XML.
Perhaps you can enable region debugging and see what's going
on. Add this above all your data sets:
Spry.Data.Region.debug = true;
Do you see any messages like:
"Generated region markup for usertags ..."
"Generated region markup for links ..."
If not, then something is choking Spry before the
notification is fired.
