[flexcoders] Flickr - Issue with LoaderContext

[Jurgen Beck]

I'm running into security sandbox violation issues trying to load images 
from a Flickr account.

Since the Image component derives from SWFLoader I am setting the 
LoaderContext before the image source is assigned. The image component 
is used inside my custom component, which in turn is used as an 
itemRenderer in a TileList.

Here is the image component code fragment:

        <mx:Image id="imgThumbnail"
            source="{data.url}"
            initialize="imageInit()"   
            width="75" height="75"/>

Here is my imageInit() method:

            private function imageInit():void {
                loaderContext = new LoaderContext();
                loaderContext.applicationDomain = 
ApplicationDomain.currentDomain;
                loaderContext.securityDomain = 
SecurityDomain.currentDomain;                  
                loaderContext.checkPolicyFile = true;
                imgThumbnail.loaderContext = loaderContext;
            }   

I've traced through the processes and the LoaderContext is definitely in 
place before the image source gets assigned, so I should be good. 
However, the application is still returning a security sandbox violation 
error stating that the connection to http://farm1.static.flickr.com/... 
was halted - not permitted from [my server].

This obviously should be working fine. Looking through Ely's 
DisplayShelf component, there are no such issues. So the question is 
what else is missing.

Anyone with some thoughts?

Thanks,
