i am not 100% sure, but i think it you're meant to use s:BitmapImage within item renderers (for mobile hero) rather than s:Image - it should improve performance (and hopefully fix your problem?)
Thanks for the reply.
I am not doing a mobile project. I am doing a Flex Project (Web Version). Also I have tried BitmapImage with no luck as well. It is seeming to me like it has something to do with the value inside the xml node. Although it is printing the same result I am wondering if the datatype is wrong.
Almost all XML and XMLList queries return another XMLList. Often, this gets
auto-coerced to a String, but some components like BitmapImage and Image
will take just about anything as a source so no auto-coercion takes place.
Try: my_img2.source = panels_xml.image_source.toString();
Added that and it works like a charm.
