[Zope] problem deleting

[Dennis Allison]

I have a script I'm using for configuration which uses Client.py.  It
moves a file to the import directory, uses Client to perform the import,
then uses Client to invoke a python script to select portions of the 
imported object and move them from the imported object to other places 
in the system.  The script then deletes the imported object (and repeats 
the process agein with another file).  

The delete does not happen when run through the web--and it fails
silently.  I see the problem as a duplication of id's when I try 
to import the next file (which has the same name) and it fails on 
a duplicate id.  

Any thoughts as to what's happening and how to work around it?
