[Zope] calling manage_addProduct from ZClass method?

[dedmundson@bigfoot.com]

I have the following hierarchy:

   - Products
       - GPScape (Product)
          - new_cell (Script)
          - Cell (ZClass)
              - split (method, Script)

I'm getting an error when my split method tries to execute:

  line 22:  gpscape = container.manage_addProduct(['GPScape'])  <<<<<< error
  line 23:  nw = gpscape.new_cell(container,'NW',cn,(cn+cs)/2,(cw+ce)/2,cw)

Here, container is an instance of Cell and I'm simply trying to
set gpscape as a convenience variable for future use, e.g., the
new_cell call in line 23.  Any idea why this is an error?

Cheers,
Darran.
