Flex soap client (interospection wizard) preloader help

Question

hey guys, i have a small problem, im brand new to flex so i haveno idea what im doin... im using the flash builder (gumbo)
and basically what im doin is getting soap data from my server using the webservice interospection wizard.
what i cannot figure out is how to popup a loader bar, indefinite or definite dosent matter...
the current code i have is:
package modules.SiteEditor{
    import mainScript.mainList;
    import mx.controls.Alert;
    import mx.rpc.events.FaultEvent;
    import mx.rpc.events.ResultEvent;
    import services.sites.*;
    [Bindable] public class siteEditor{
        // variables
        public static var siteTitle:String;
        public static var siteListData:Site;
        public static var siteService:Sites = new Sites();
        public static var isUpdated:Boolean = false;
        public static function init():void{
            siteService.addEventListener(ResultEvent.RESULT, resulting);
            siteService.addEventListener(FaultEvent.FAULT, fault);
            siteService.GetSite(mainScript.mainList.siteId);
            //Alert.show("here");
        public static function resulting(event:ResultEvent):void{
            siteListData = event.result as Site;
            siteTitle = siteListData.siteTitle;
            isUpdated = false;
            //Alert.show(siteListData.siteTitle);
            //Alert.show("done");
        public static function fault(event:FaultEvent):void{
            Alert.show(event.fault.faultCode);
            Alert.show(event.fault.faultString);
i have a vague idea about how to do this, but it dosent work...
what i tried to do is add another event listeler in the init function but i cannot see loadingEvent in the drop down list that pops up... if that makes any sence...
All i want to happen when the init function is called is a loader bar to popup.
thanks a lot in advance
