well, yes. It gives me:
->Error Type: SystemError
->Error Value: bad argument to internal function
I think the problem is that getitem() accepts only two arguments, the
second of
which is a flag of 0 or 1, whereas in your example it would be a string.

I'm really a little annoyed... actually, this is a very simple task, but
I don't
get it.
I just tried to workaround it with manage_copyObjects() and
manage_pasteObjects()... (not very smooth),
but I get an error, too:

Maybe someone from Digital Creations have an idea?
