[Zope] Please Help! - Changing instance owner with external script...

[M. Adam Kendall]

Ok, the custom_changeOwnership method is expecting
(basically) two arguments.  The first one is the
username that you would like to change ownership to,
and the second is the actual object that you would 
like to change the owner of, not simply the name of
the objext..  So, you have to first get an object 
reference (using getitem)

I'm guessing you are creating an object with an id
of the username in your script, so you would do something
like:

request = context.REQUEST
request.set('id', request.form['name'])
tmpObj = context.members.manage_addProduct['MyProduct']
tmpObj.Member_add(tmpObj, request, NoRedir=1)
obj = context.getItem(request.form['name'])
context.custom_changeOwnership(request.form['name'], obj)

HTH,
Adam
