Complex: Saving a clone to a Shared Object

(I see this same type of question was posted almost three years ago with no resolution, does anyone have a solution now?

I am trying to save a clone of a custom object (contains arrays and other custom objects as properties) to a Shared Object.

Basically I have a menu system that created this program, it’s running and at any point I want the user to be able to save it so he can go back to that exact point at a later date. Here is what I do so far:

  1. Pause the program
  2. The menu saves the variable that references the running program using a bytearray to a shared object
  3. A a later time, to load the program I pull the data from the shared object and save it to a variable, which I then treat like the original program

Here is my code to save the data:

var byteArrayCloner:ByteArray = new ByteArray();
byteArrayCloner.writeObject(myProgram);
byteArrayCloner.position = 0;
mySharedObject.data["myProgram_Running"] = byteArrayCloner.readObject();
mySharedObject.flush();

But it doesn’t work correctly, when I save the data I get several #1034 errors:

TypeError: Error #1034: Type Coercion failed: cannot convert Object@12ee0421 to org.papervision3d.core.proto.MaterialObject3D.
TypeError: Error #1034: Type Coercion failed: cannot convert Object@12f1d881 to flash.geom.Transform.

So I read how I am suppose to use “registerClassAlias” to remove those errors. I started adding them, like this:

registerClassAlias("SpriteAlias", Sprite);

The errors started to go away, I then tried:

registerClassAlias("TransformAlias", Transform);

This caused an error when I tried to save the data:

ArgumentError: Error #1063: Argument count mismatch on flash.geom::Transform(). Expected 1, got 0.
at flash.utils::ByteArray/readObject()

I don’t use flash.geom.transform, but I do use TweenLite, which uses it. What am I doing wrong here? How do you save a custom object to a shared object without any errors?

Thanks for any help.
