Ok thanks, understood..
The fact is that the first object is a Mysql DB Handler and the second
is a DB Session Handler.
In the DB Session the parameter initially was the link to Db obtained
from the Db handler. The destruct method of the Db handler close the
connection so i lost the Db link and the possibility of writing the
session on the Db. I wanted to avoid to open 2 connections.
I "solved" the problem by not closing conection to the Db in the
destruct method but leaving this role to the end of the script (with no
persistent connections).
