As LEE Kwan Soo has already said, it is not a bug, but a clever (too
clever?) feature that should maybe not be enabled by default. Every second
week or so somebody runs into this and thinks it is a bug.

Kind of. Probably not full-fledged Products, but ZClass-like Classes that

Hi!
When I read about the reload functionality of Zope 2.4, an old vision came
back to my mind:
If we can reload Python code at runtime, and we can also edit, generate and
store files (containing code) via the web (as LocalFS or extFile prove),
then it should be perfectly possible to have somet

Have you tried to use the newest Zope version? In 2.3.0 or so there was a
bug that gave us the "unsliceable object" error for ZClasses that are based
on "Image" or "File" (which should be similar to the DTMLDocument case).

I don't know if this helps a bit: It's the code used in KONTENTOR for
putting the session into the REQUEST namespace. I think it is not the most
elegant way of doing this, but it se

What we experience with CoreSessionTracking:
We have a manage mode in the Kontentor CMS hacky thing (no, it is NOT a
product yet ;-)). It works well for some time (i.e. if I click on it, the
system switches to manage mode and stays in manage mode until I click
again), but from time to time it is

Hi!
Anyone seen this before?
It happens when I want to access a folder's "manage_access" page. The thing
worked all the time, and I don't know what could have changed that. The Zope
version is 2.3.1. source version with Python 1.5.2. There also seem to be
problems with some of the permissions se

Hi!
We are currently developing a groupware system with Zope. As usual, the options
for the storage back-end are using a SQL DB (postgres, ...) or ZODB.
I know that this question has been asked a thousand times. But I'll repeat it
for our specific situation:
SQL or ZODB+ZCatalog, which one is
Zope 2.3 and creating the correct object types (has been discussed
earlier, I think):
There is a bug with this that only becomes visible with some FTP clients
like the KDE2 Konqueror: If the clients do partial uploads and renaming
(which finally works), the type is not recognized correctly. Th
Hi!
Is there anyone who has tried using Zope on QNX? I have a request for
using Zope in an embedded environment.

Hi!
There is a little Bug in the new GUI: If you creat a new Folder that is
empty, only "There are currently no items in foo" is displayed. So you
can't import stuff before you have created an object in the folder. The
import/export tab has also gone.
