[Zope] cut and paste or an object

[Terry Kerr]

Hi,

I have written a product in python which has two classes.  One is a
contrainer class, and the other as an item.  Both classes are
catalogAware.  Both have management interfaces which allow
cut/copy/paste.  Copy and paste works fine.  But if I paste an object
that has been cut, i get the error:

Traceback (innermost last):

  AttributeError: aq_acquire

The only difference between cutnpast and copynpaste is that cutnpaste
will remove the object before setting the new object.  The problem seems
to lie in obtaining the absolute_url of the object to be removed which
is need by CatalogAware to unindex the object.  I dont understand this,
as a direct call to _delObject() from the contrainer class works fine,
so I don't understand why a call to _delObject from within the
manage_pastObjects method results in the above error.

I have been trying to figure this out for days.  Can anyone shead any
light on the subject?
