The result:

Error Type: TypeError
Error Value: object doesn't support item deletion

Traceback (innermost last):

    * Module ZPublisher.Publish, line 98, in publish
    * Module ZPublisher.mapply, line 88, in mapply
    * Module ZPublisher.Publish, line 39, in call_object
    * Module Products.OOPServer.Demo.Demo, line 200, in deleteAllObjects
    * Module OFS.ObjectManager, line 448, in manage_delObjects

TypeError: object doesn't support item deletion

My object is inherited from the following classes: SimpleItem,
Persistent, Implicit, CatalogAware

The container is a BTreeFolder2. 

objectIds() does not return a list, but: <OOBTreeItems object at 0x93b1a68>

BTW, the problem is not important, because my code works. I am just
looking for cleaner solution.
