Hi all,
First, the background:
I am creating a Flex application with a component that displays various
dynamically loaded SWFs, one at a time (kind of like a kiosk). These loaded
SWFs are created in Flash IDE, not Flex. They will not be created by us (we
will provide a .fla template but that's it), so I am loading them into a
separate SecurityDomain.
My Questions:
1. I want the application to be able to call methods inside the loaded
SWF. To do this, would I just call Security.allowDomain("domain original app
was loaded from") in the startup process for the loaded SWF?
2. I want the loaded SWF to be able to throw events that are caught by
the application. Can I accomplish this through the
<http://www.adobe.com/livedocs/flex/3/langref/mx/controls/SWFLoader.html#swfBridge>
SWFLoader.swfBridge property?
3. I am defining an interface for the methods inside the loaded SWF. But,
I don't want to leave the implementation up to the customer. Instead, I want to
provide another SWF that contains the interface implementation and have it be a
constraint that the customer includes it in their SWF. I am not very familiar
with the Flash authoring environment, how would it work so that the interface
implementation SWF exposes its methods in such a way to be accessible to Flex?
Is there a way to sign the SWF so that the Flex application knows that it is
dealing with the original, not a spoof? How would the Flex code pass in
arguments, since it is across SecurityDomain boundary -- is there marshalling
involved (say if I want to pass in a Dictionary or some kind of object graph)?
4. The Flex application may load hundreds of these smaller other SWFs
during its lifetime. How do I make sure it doesn't keep using up more memory? I
plan on using SWFLoader.unloadAndStop() and clearing all references in the Flex
object that refers to it. Is this enough? Will the AppDomain for the loaded SWF
be torn down automatically so that the class definitions are no longer in
memory?
Thanks,
Karthik
