Hello,

I'm working on an application in which students uses data like the times of tides. It uses an rss-feed to fill up an Arraycollection, it cuts out the times and then put those times in a datagrid. I have a neat little table in a Tilewindow. Here's the code:

<?xml version="1.0" encoding="utf-8"?>

<mx:TitleWindow

xmlns:mx="http://www.adobe.com/2006/mxml

"

title="

Getijdentabel (Oostende)" xmlns:p="*" width="734" height="258" creationComplete="test.send()" verticalScrollPolicy="off" horizontalScrollPolicy="off" showCloseButton="true" close="PopUpManager.removePopUp(this);"

It works fine on my computer, but it fails when I've uploaded it to the server. Any hints to solve this problem? Bear in mind I'm not a professional programmer.

Have a nice weekend,

PS. I added

<mx:Button label="Gegevens inlezen" y="170" right="0" click="test.send()"/> but even this won't work.

needs to allow your swf file to connect and invoke the service

its done by adding crossdomain.xml file to that server,
