Possible oddity: for a while I was using two browsers under the same login to manipulate the database through the management interface. However, I have since curtailed that activity under the suspicion of it NotWorkingQuiteRightThatWay(tm), but I am still receiving the unpickling errors on occasion. > Is it a plain Folder, or a folderish object from some Product? Plain Folder, populated with ZSybaseDA connections and SQL Methods. > When you say that the unpickling error is sporadic, do you mean it comes > and goes with no action on your part, or that you fix the ZODB somehow, and > the problem reoccurs at an unpredictable later time? Occasionally, I will get ZOPE errors reporting that it cannot find the folder within which I am attempting to change a DTML Document. Typically, if I hit the back button and retry, the second try will succeed. When this event happens, there is always an "unpickle" error message in the shell session within which I am running the ZOPE process. When the folder "went away", I received the "possible broken product messages". These messages continued whenever I attempted to access the folder, until I restarted ZOPE (which incidentally will also cure the unpickle problems temporarily), at which point I had to commit my current session before the folder was accessible again. Hope this helps. Regards, -scott

Thanks for the hint, but it doesn't work for me. If I add start=0, nothing happens. Zope always shows 7 entries instead of 5. - Achim On Sep 15, 9:58, Evan Simpson wrote: > Subject: Re: [Zope] #in & reverse sort + size > I ran into a similar problem, and "solved" it by putting in a dummy start > clause.

ZMySQLDA troubles in Zope 2.0
by ben andrew fulton 15 Sep '99

15 Sep '99

Hi, Got the DA compiled yesterday, and now I'm having all kinds of trouble getting some semi-complex queries from my old perl scripts to work. Below is the response given by Zope to a good example: --- Error, exceptions.KeyError: unhandled SQL used: select i.name, c.language, c.notes, c.condition, c.bid, c.cardnum, i.rarity from cardinfo i, cards c where i.cardcode=c.cardcode order by i.name limit 10 Traceback (innermost last): File /usr/local/dc/Zope-2.0.0/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/dc/Zope-2.0.0/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/dc/Zope-2.0.0/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: test_listing) File /usr/local/dc/Zope-2.0.0/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/dc/Zope-2.0.0/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_test) File /usr/local/dc/Zope-2.0.0/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_test) File /usr/local/dc/Zope-2.0.0/lib/python/Shared/DC/ZRDB/DA.py, line 316, in manage_test (Object: test_listing) File /usr/local/dc/Zope-2.0.0/lib/python/Shared/DC/ZRDB/DA.py, line 297, in manage_test (Object: test_listing) File /usr/local/dc/Zope-2.0.0/lib/python/Shared/DC/ZRDB/DA.py, line 401, in __call__ (Object: test_listing) File lib/python/Products/ZMySQLDA/db.py, line 191, in query KeyError: (see above) --- Simple, one-column queries seem to work fine. A search of the mailing list archives on "unhandled" didn't bring up much except one other person who'd had a similar problem and wasn't able to find an explanation. MySQL is version 3.21.33b and the query works fine when tested from the MySQL monitor. -->ben

#in & reverse sort + size
by achimg＠obelix.cologne.sgi.com 15 Sep '99

15 Sep '99

Hello Zope users! I've a folder containing 7 DTML Documents. The construct below should print 5 title/id, but Zope-2.0.0 displays all seven?! If I include one more DTML Document, only 5 title/id are shown! Why is the correct number shown with 8 documents but not with 7 documents?? Thanks for your advice. - Achim   <strong> </strong>   -- Silicon Graphics GmbH | Email: Achim Gorski <gorski(a)sgi.com> Frankfurter Str. 720-726 | Phone: +49-2203-9312-24 D-51145 Koeln, Germany | VM : +330-8891 Mail-Stop: IDE-3160 | Fax : +49-2203-9312-20

Database connection via SOLID
by Jan-Thies Baehr 15 Sep '99

15 Sep '99

Hi, I'm looking for some experience regarding a connection from Zope (1.10) on Unix to an MS Access Database on WinNT via Solid. The harder part for me seems to be the Solid Connection from Unix to WinNT/ODBC. Is there someone who managed to establish such a connection and who is also willing to give a short howto? I know, it's a bit offtopic here, because it's more of a Solid problem but the solid mailing list archives and the administrators guide did not provide much help for me... Thanks in advance, Thies Bähr.

content_type=text/html ??
by Geir B Hansen 15 Sep '99

15 Sep '99

Does anyone know how i can make zope output a correct content_type=text/html in the http-header of documents when delivered to browsers ? It works fine if i add a propery called content_type to a document with string value of text/html to the DTML-document in the manage-interface, but i (obviously) do not want to manually add this to all the documents in my site. thanks . ------------------------------------------------ Geir B Hansen geirh(a)funcom.com Web-designer / Graphic artist Funcom Oslo ------------------------------------------------
