I have created a zclass with zfile as basic class.
With this class, users could, via a web form, send an attached file if
they want.
With zope 2.5 (my previous version) if users don't attach a file, there
is no problem
with zope 2.10, if there is no file attached, I have an error message :
'file not specified. It seems that  attach  file is mandatory.

Here, the complete message from the events log :

I cannot tell you what changed since Zope 2.5 (this is far too long ago).

I can tell you why you get the exception above in modern Zope versions:

  A modern Zope version insists that if the file parameter
  to OFS.Image.File.__init__ is a FileUpload object, then
  it must have a non empty filename.

You may be able to use this in your Quest_susvp_add method as follows:

  You check whether the uploaded file is False (this means empty
  filename) and in this case replace it in REQUEST.form with
  an empty string.

Not sure that it will work, though.
