Re: [AFFUG Discuss] ItemRenderer causing null error issues

How can you call an initialize function on an 
itemrenderer and not receive a null error.  I 
need to read the data from a loaded xml file but 
it appears that the data isn’t there yet when 
the initialized function is called, I tried to 
use creationComplete as well still no 
luck.  Here’s an example of what I’m trying to 
do, if anyone has any suggestions I would appreciate it.

<VBox xmlns:mx”…. Initialize=”init();”>
<script>
<![CDATA[

Private function init():void{

Var myVar:Number = data.myNumber;

myVar += 2;

trace(myVar);
}

</script>

How are you loading in the XML data?  If it's an 
HTTPService, then simply call the HTTPService's 
.send() method in your init() function, and put 
the work you need to do with the loaded data into 
the HTTPService's resultHandler.
