Re: [flexcoders] help with a repeater

Thank you my friend, you are really good. I guess I should have read  
more the book. It totally works.

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.

                        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.
