XML info flash template

Hi,
I’m trying to get a flash template to retrieve data from an external xml file. But I do not make it work.
I think the problem is in the class AS file. Because it works when I put the code on frame one.
Can someone have a look and help me?

AS

package
{
	import flash.display.MovieClip;
	import flash.net.URLLoader;
	import flash.events.Event;
	import flash.events.TimerEvent;
	import flash.net.URLRequest;
	import flash.utils.Timer;
	import se.svt.caspar.ICommunicationManager;
	import se.svt.caspar.IRegisteredDataSharer;
	import se.svt.caspar.template.CasparTemplate;
	
	public class databas_nya extends CasparTemplate 
	{
		private var myXMLLoader:URLLoader;
		private var myTimer:Timer; 
		
		private function timerListener (e:TimerEvent):void
		{
			myXMLLoader = new URLLoader();
			myXMLLoader.load(new URLRequest("databas.xml"));
			myXMLLoader.addEventListener(Event.COMPLETE, processXML);
		}
		
		private function processXML (e:Event):void
		{
			var myXML:XML = new XML(e.target.data);
			f0.text=myXML.namn;
			f1.text=myXML.title;
		}
	}
	
	
}

There are a few functions that should be overwritten. In the old doc (before GitHub) there was a description of this, but I did not find it any more. At least you should add a postInitialize function:

override public function postInitialize():void {
   //code here
}

Inside this you should initialize and start the timer, as this is called by the TemplateHost after the template is loaded and before anything else.

Okay thanks for your reply, I think I understand what you mean and I have tried adding “postInitialize (): void” but it does not work either.

Here is the code:

package  {
	
	import flash.display.MovieClip;
	import flash.net.URLLoader;
	import flash.events.Event;
	import flash.events.TimerEvent;
	import flash.net.URLRequest;
	import flash.utils.Timer;
	import se.svt.caspar.ICommunicationManager;
	import se.svt.caspar.IRegisteredDataSharer;
	import se.svt.caspar.template.CasparTemplate;
	
	public class databas_nya extends CasparTemplate {
		
	override public function postInitialize():void
   {
	var myXMLLoader:URLLoader = new URLLoader();
	myXMLLoader.load(new URLRequest("databas.xml"));
	myXMLLoader.addEventListener(Event.COMPLETE, processXML);

	function processXML (e:Event):void
	{
		var myXML:XML = new XML(e.target.data);

		f0.text = myXML.namn;
		f1.text = myXML.title;
		
		}
		}
	}
}

Can you see what I did wrong?

var myXMLLoader:URLLoader = new URLLoader();

must be defined outside the postInitialze function, because otherwise it only lives inside of this function.

Thank you so much for trying to help me.
I’m not getting the code to work. I have no idea what I’m doing wrong and I’ve tested your idea of postInitialze function.

If you get the time and can check the files I have attached I would appreciate it. But again thanks for all the help.

I got some time to test it and got it working.

			xf0.text = myXML.namn;
			xf1.text = myXML.title;

Thank you so much for changing the code for me.
Now it works and I have tested the template on my server.
This really helped me.
Thanks again!
