[Zope] XMLDocument manage_edit from DTML

Hi, I am trying to create a new XMLDocument object and then stuff some data into it - all from DTML. I can create a new default XMLDocument with: <dtml-with "manage_addProduct['XMLDocument']"> <dtml-call "add('testid', 'testtitle')"> </dtml-with> After I create the new XMLDocument, I would like to do something like: <dtml-call "testid.manage_edit(data='New Data for the XMLDocument')"> The stumper is, this call doesn't throw any errors, but it also doesn't change the data! Any ideas? Pls respond directly to eric@walstads.net as well as the list (I'm not on the list). Thanks, Eric.
