No, I don't forget to set the id. All objects which my product contains do have
an id:
    # in __init__
    self._setObject(add.id, add)
    self._setObject(search.id, search)
    self._setObject(conn.id, conn)
    WARN("add.id: %s" % add.id)
    WARN("search.id: %s" % search.id)
    WARN("conn.id: %s" % conn.id)

>>> app.inventory.id
'inventory'
>>> app.inventory.add.id
'add'
>>> app.inventory.search.id
'search'
>>> app.inventory['db-connection'].id
'db-connection'

Also I can see it in the log file:

2005-08-12T10:31:17 PROBLEM(100) Inventory add.id: add
------
2005-08-12T10:31:17 PROBLEM(100) Inventory search.id: search
------
2005-08-12T10:31:17 PROBLEM(100) Inventory conn.id: db-connection


But the connection still can only be found if it's in the root folder. That's
really weird.
