In the past week it appears that Yahoo has changed their crossdomain file to only accept Yahoo domains (http://maps.yahooapis.com/crossdomain.xml):
This is causing my applications that use Yahoo Maps to stop working (i.e. security exception). I cannot proxy the calls to Yahoo because the URL is embedded in the MXP file that Yahoo distributes. Does anyone know if there's a workaround or update to this?
Thanks for posting this. I too have just recently noticed an application I wrote a few years ago has stopped working. I had no idea what the cause was, but the map is no longer loading. I suppose it is due to this crossdomain file change. Strangely, I can't seem to find any other posts on the web about this problem.
Interestingly Yahoo's own examples on the following page aren't working right now either: http://developer.yahoo.com/maps/flash/asGettingStarted.html
I am having the exact same problem with my Yahoo Maps API application. It worked fine yesterday, now it's dead.
