I'm having trouble with an AS3 AMF RemoteObject request that is hosted on App Engine. I have a crossdomain.xml file in the root of the domain, and also one at the remoting endpoint.
Here are the contents of the root crossdomain.xml:
<?xml version="1.0"?>
<cross-domain-policy>
<site-control permitted-cross-domain-policies ="all"/>
<allow-access-from domain="*.appspot.com"/>
<allow-access-from domain="*.{appid}.appspot.com"/>
<allow-access-from domain="*.{appid}.com"/>
<allow-access-from domain="*.{appid}.org"/>
</cross-domain-policy>
I have replaced my application's ID with {appid}. In the endpoint crossdomain.xml, it says the exact same thing, except it omits the <site-control> tag.
Loading the swf file and testing it on my machine works just fine... I think that may have something to do with me having the debugger version of Flash Player. When I push it up to App Engine to make it public, other clients access it and get a Client.Error.MessageSend Channel.Security.Error error Error #2048 url: http://05-alpha.latest.{appid}.appspot.com/_rpc/data.
I am using Flex 4 beta, and the App Engine Python runtime. I have tried full wildcard in the crossdomain, and even accessing the data endpoint at a relative URL so as to avoid this error.
Someone please help! Thanks in advance.
