Sure... you *can* get the address of an object by getting the string
representation of it using backticks, ex:


A better way might be something some Python like this:

for obj in container.objectValues(my_obj_type)
    if hasattr(obj, attribute_name):
      print obj['id']
return printed

That would give you a list of *all* the objects that lack the specific
attribute, not just the one that you think you're looking for.
