It is my understanding that the Native Flash Objects are assembled automatically in the Flash player based on the AMF data sent. Just as if you had a custom XML-based object representation and a parser. Therefore there wouldn't be such a way to do runtime memory referencing unless the protocol supported it explicitly.

Hello,

imagine the following scenario:

- backend in AMFPHP;
- a remote procedure that returns a complex type:

Categories[]
    CategoryVO (#12334)
       id: 1
       name: Accounting
       etc...
    CategoryVO (#34221)
       id: 2
       name: Reporting
       etc...



- Another remote procedure that returns another complex object:

   UserVO (#5456)
       id: 1
       name: John Doe
       CategoryVO (#2145)
          id: 2
          name: Reporting

The category of the user John Doe is "Reporting", id 2. It's the same previously returned by the other service, on the position 1 of the categories array. The problem is that, on the client side:

categories[1]==user.category

is false. It's the same category, the problem is that when the object mapping occurs on the client side, it creates a new reference, so they are different instances of the same object. Right now, we need to make some loopings on the client-side to find and replace references. This involves a lot of work, and has performance considerations.

Is it possible, or is there a solution to make same objects returned from the server side have same references on the client side?

Thanks,
