Instantiating the object (chainedState) is not enough to define all the info needed in
that case.
The object must be placed in a chain first (and placing can't be done by chainedState
constructor).

Yes of course, I can add a flag, so that postProcess will do nothing by default. Simple
initialization will let the flag false. Putting a body in a chain and saving will turn it
true, loading will turn it false, or something like that. I just wanted to know if there
was a simpler solution before starting such things, since the code is really only suppose
to be executed at load time.

Thanks.
