While loading an swf in my flex application i observe the following:
I suppose that this is an issue of security sandbox but i do not know how to overcome this (no security sandbox violation messages for this swf appear while debugging)
Make sure the main application and the SWF are loaded from the same domain otherwise you'll need to use the MarshallPlan. The same domain means the domain are the same using a string compare. IP addresses and the server domain (abc.com) may resolve to the same server but it is considered a different domain to the Flash Player. If you really want to load SWFs from a different domain, then you will need to use the MarshallPlan. To use the Marshall Plan compile your application with "-incudes mx.managers.systemClasses.MarshallingSupport".
