RE: [flexcoders] help with a repeater

[Gordon Smith]

This poorly-worded message is trying to explain that you cannot access the 
'currentItem' of a Repeater, as your code vimeo.currentItem.title in 
openWindowVimeo() is doing, after the Repeater has already created all the 
repeated components. As each repeated component is created, 'currentItem' is 
the item in the dataProvider that is creating that particular component. So 
what would the 'currentItem' of the Repeater be after all the components have 
been created? It doesn't make sense, and therefore is an error.

Once a repeated component has been created, you can use its getRepeaterItem() 
method to get the item in the dataProvider that created it.

<mx:Script>
                        <![CDATA[
                        import mx.managers.PopUpManager;
                        import mx.containers.*;
                                    import mx.controls.Alert;
                                    import mx.rpc.events.FaultEvent;
                                    import mx.rpc.events.ResultEvent;
                                    import flsWindow;

                                    private function 
openWindowVimeo(event:MouseEvent):void{
                                                var myVimeoWindow:TitleWindow= 
TitleWindow(PopUpManager.createPopUp(this, flsWindow, true));
!
myVimeoWindow.title=vimeoService.lastResult.video.title;///this is the one 
using the xmlList,
it works but only the last title and with tags there is a way that my different 
video titles will be in the opened windows?
also when I try using the repeater like:
myVimeoWindow.title=vimeo.currentItem.title
is always giving me and error.

                                    }
