I added:
private function resultHandler(event:ResultEvent):void {
myData = event.result.sites.site;
trace("myData.length: "+myData.length);
myData.removeItemAt(0);
trace("myData.length: "+myData.length);
}
and corrected your xml by closing the <sites> markup.
and saw:
myData.length: 2
myData.length: 1
So, no problems with the solution!
