[Zope] Re: ref another file while adding file in ZMI

[Patrick Price]

OK my original assumption was wrong, I was curious to try adding a Zope 
object as the File specification.  I had thought it actually copied the 
object, however it did not.  I thought it had.  Although it *will* take 
an argument for a File which does not exist (ZMI bug?).  I was not using 
the Browse button.

This was one of those stupid newbie attempts to see what the 
capabilities of the interface were.  My line of thinking was "since a 
file is an object, and it's asking me for a File object, I'll try a Zope 
object and see what it does."
