Hi, I'm also getting similar problems, that I can no longer export and it is giving me AttributeErrors. I think I've scanned every Zope document but cannot find any info. I am running Zope from my own user and not from a root account and I have also installed WorldPilot (perhaps related to this)? Any ideas ... I'll post more details if I find anything, as this is delaying a release Regards Gresh !------------------------- Hi, My Little Problem : I have zope version 2.1.6 running on two servers. I have a folder containing dtml methods and zsqlmethods which I want to import from server A to server B It doesn't work. It used to work, but not any more. this is the error it throws... File /usr/local/Zope-2.1.6-linux2-x86/lib/python/OFS/ObjectManager.py, line 484, in manage_importObject (Object: ElementWithAttributes) File /usr/local/Zope-2.1.6-linux2-x86/lib/python/ZODB/ExportImport.py, line 266, in importFile ExportError: (see above) Help Regards Ronnie

ZWN-2000-06-01 says: "Itamar Shtull-Trauring and Chris Withers tracked down a problem with image caching that affected certain versions of Netscape browsers." Can anyone give me more info on this? I missed any reference to it on the list and have been unable to locate anything in various archives. I have just such a problem and I hope this is a fix.

Confera and strict permissions
by Cary O'Brien 07 Jun '00

07 Jun '00

I'm trying to set up a small site with a Confera topic (using Zope 2.1.6). It is going to be accessed by some off-site co-workers through the internet, so I am concerned about security. Access is through Apache on the firewall with some mod_rewrite address filters, but I'm kind of a belt-and-braces guy when it comes to security, so I only want people who have user entries and passwords to access the discussion. No anonymous access at all. But, if I remove the default "Anonymous" access privileges granted in the root folder, even users with user entries who can access other documents get access denied when trying to view the Confera topic. This happens for both remote and local access. The error traceback seems to point to a problem with the tree tag rendering components. Any ideas? -- cary (Currently kind of frustrated with Zope. Everything seems hard.)

You need the traceback from the request that failed. Other than that, you can't do much but restart. Anthony

Error Type: TransactionError

Dear All: OS: RH Linux 6.1 Zope: 2.1.6 Python: 1.5.2 Extra Products: ZOracleDA, FSSession, Document Template I just encountered a series of errors throwned out from my production Zope with type TransactionError. The coresponding error value says: """ A serious error, which was probably a system error, occurred in a previous database transaction. This application may be in an invalid state and must be restarted before database updates can be allowed. Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem. """ The trace back did not say much: """ Traceback (innermost last): File /usr/local/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 169, in publish File /usr/local/Zope-2.1.6-src/lib/python/ZODB/Transaction.py, line 209, in commit TransactionError: A serious error, which was probably a system error, occurred in a previous database transaction.

Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem. """ I am almost clueless about this error, and it prevents the system from being accessed until zope is restarted. Please help!

newbie: zope not finding python libs
by Daniel Chudnov 07 Jun '00

07 Jun '00

I've had a series of problems getting products to install correctly and importing some test external methods to go; each of these seems to be related to zope finding the right python libraries at the right time. Looking through the misc docs I find comments about PYTHONPATH but nothing that indicates whether this might be the issue, or if this is another common install/admin issue I'm overlooking. Is there a runtime config or compile thing I need to do to make sure zope has the right path(s) and finds everything? Do I need to install duplicate libraries into the zope/lib/python dir (I hope not :)? I also saw somewhere (one of the mysql products?) that installing necessary libraries from source was better than rpms (I'm running rhlinux6.0, Zope 2.1.6, python 1.5.2-2) but don't recall finding any specific strategy for good share dirs Zope will find. Any help would be greatly appreciated. If there's a how-to or the like I missed, I'm sorry but this is hard to find. And I'm a librarian so I'm usually good at finding things. :) Happy to provide product/library specifics if necessary, too. Thanks, -Dan

Greetings, I wish to use use the data of the database file in my html code. For example, this database was last updated on 06/06/2000. I suppose that there must be a dynamic html tag that zope uses. What could it be? I looked at all the documentation and have yet to discover it. <DTML-ZOPE-FILE-DATE> Any help is apprechiated.

sort_order???
by michael angelo ruberto 06 Jun '00

06 Jun '00

hello, ok, here is my code: <dtml-in table-1 sort=date> <a href="<dtml-var URL>"><dtml-var name></a> | <dtml-var value> | <dtml-var URL> | <dtml-var attendee> | <dtml-var date><br> </dtml-in> what's wrong - nothing, it works fine. however, the result is sorted by date ascending and i need it to be reversed. i found a reference to an attribute "sort_order" which can be given an arg such as "sort_order=reverse". the problem here is that it won't work and i can't find any usage info on "sort_order". it isn't mentioned in the DTML Reference and after hours of searching the Zope website i am empty handed. does anyone know how to use this? thanks in advance. -<mike>-
