Hello Smola,

Im not sure your object model makes sense...

You want a class to maintain a list of instances of that class? How do you
know which one is the main class? This is very similar to the Registry pattern
from PoEAA, and in that pattern you have a separate class that handles the
registry of objects.

Once you do that, the serialization should just fall into place...
