I think I am following what you are saying about setting the result type, but I am unsure of how to set it. I see from the Flex 3 API documentation that on the WebService you can set the Operation type, but it is done through the mx:operation tag and not through the WebService class itself (although their is a protected method initializeOpertion on the WebService).
Is Flex like Java, where if I want to have access to that protected method, then I need to create a class that extends the WebService and is located in the same package structure? Is this what you were thinking by the setting the result type? If so, which type? Object? <mx:operation Properties concurrency="multiple|single|last" name=No default, required. resultFormat="object|xml|e4x" makeObjectsBindable="false|true" Events fault=No default. result=No default. /> If I do return it as an object, then do I need to write my own attachments class that will "know" how to handle attachments? Oh, I do not think I mentioned this yet, but I am using Flex 3 beta 2.
