Google Maps in Flex Component

Question

I'm embedding the Google Maps Flash API in Flex and it runs fine locally with the watermark on it, etc. When I upload it to the server (flex.mydomain.com) I get a sandbox security error listed below:

SecurityError: Error #2121: Security sandbox violation: Loader.content: http://mydomain.com/main.swf?Fri, 12 Sep 2008 21:46:03 UTC cannot access http://maps.googleapis.com/maps/lib/map_1_6.swf. This may be worked around by calling Security.allowDomain.
    at flash.display::Loader/get content()
    at com.google.maps::ClientBootstrap/createFactory()
    at com.google.maps::ClientBootstrap/executeNextFrameCalls()

Does anyone have any experience with embedding the Google Maps Flash API into Flex components and specifically settings security settings to make this work? I did get a new API key that is registered to my domain and am using that when it's published.

I've tried doing the following in the main application as well as the component:

Security.allowDomain('*')
Security.allowDomain('maps.googleapis.com')
Security.allowDomain('mydomain.com')

This sounds like a crossdomain.xml related problem? I did a quick search and there seems to be many people with the same issue. Some proxy requests through XMLHttpRequest etc..

Thanks for the help. Apparently this has something to do with including the Flex app on an ASP.NET page. When I moved it over to a flat HTML file, it worked fine. I don't have time to fully investigate right now, but that seems to have fixed it.
