[TYPO3-mvc] Dependency injection on object unserialization

But the serialized state shouldn't contain objects like an 
ObjectManager, ObjectStorage<AnyChildObjects> or any deeper nested 
objects. Thats why i throw them away on serialization.

O.K., thats what im doing so far...

I want to serialize a basket object (containing products with 
categories assigned and so on) and on serialization of the products i 
throw anything away but their uid and unserialization it restore the 
rest manually.

Therefore it would be more comfortable if dependency injection would 
work on unserialization, but i understand your theory ;)

Thanks a lot!

Kind regards, Jan
