How was the object created? Did you use "new" or was it created by ExtBase from the repository? In
the latter case the constructor will not be called as the objects are instantiated by some magic
from a serialized "fake object".

Try to put your code in the initializeObject() method which is also called at wakeup (see abstract
domain classes).

Why the objects storages are initialized normally without calling the constructor is still a mystery
to me.
