Hi Kiran.
I think you should create a "ModelLocator" singleton class, that gets and
store the xml information. It would be something like this:
public class MyModelLocator
{
private static var _instance: MyModelLocator;
private var _data:XMLList;
public function MyModelLocator() {
if (_instance != null)
trace("Constructor shouldn't be called directly... now
I'll have to kill you")
_instance = this;
this.initData();
}
private function initData():void {
//Load data....
}
private function onDataLoaded() {
//Store data
this._data = [loaded data];
}
public static function getInstance():MyModelLocator{
if (! _instance)
_instance = new MyModelLocator();
return _instance;
}
public function get data():XMLList {
return this._data;
}
}
In order to get data in each combobox, you would set
dataprovider="{MyModelLocator.getInstance.data}" (if that XMLList already
has the correct structure to be directly used as a dataprovider in the
combobox... otherwise now is the time to change it ;) )
This way:
- There's only one instance of MyModelLocator at anytime, anywhere.
- initData is called only once, so the data is retrieved only once.
- By storing the data within the singleton class, it's available to the
whole application by just importing the class.
Hope it solves your issue.
Best regards
Andrea.
