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

[Tim Hicks]

Patrick,

if I understand you correctly, you are trying to use the add File screen of
the ZMI.  In the 'File' (file upload) box, you are trying to reference a
file in the ZODB.  If that's right, it'll never work coz the browser simply
reads the path in the box, finds that file on your local system, then
uploads it.  It is entirely separate from the ZODB at that stage.

Or have I misunderstood you?
