[flexcoders] PhotoView App Problem

[cjsteury2]

heres my problem.

If I try to modify this app so Carousel is default in Viewstack (move to top)...

http://www.adobe.com/devnet/flex/samples/photo_explorer/

Then the Carousel component calls a resize="carousel.reset()"

event on app load which throws an error 1/2 the time referencing null object...

the resize events fits the images on the screen...  how can I load this  
carousel.reset event so that it waits for viewstack to build... or do I set the 
creationPolicy different than it is .. 'queded'

Its a problem.

                public function reset():void
                {
                        var selected:int = gallery.selected;

                        picDimension = new Array(9);
                        picPos = new Array(9);

                        picDimension[2] = appWidth*.10;
                        picDimension[3] = appWidth*.15;
