We've had the same problem, Michael Pelletier addressed this question in a previous post, Check out: http://www.egroups.com/message/zope/29589?&start=29498 To summarize, 'Zope doesn't like it if there is no html tags before the DTML begins.' To fix our problem, we simply make sure that a html comment as the first line in every page, through the standard_html_header.

Invalid Header (0) error
by Richard Moon 23 Jun '00

23 Jun '00

Does anyone know what an Error Type: Value Error, Error Value:Invalid Header (0) error represents ? It's interesting in the way it shows itself up. I added a <dtml-var a_dtml_method> to a dtml method and it generates this error. This <dtml-var a_dtml_method> is nested inside a <dtml-if> and would definitely not be rendered the first time the 'calling' dtml-method is rendered. I took out the <dtml-var a_dtml_method> and I still got the same error. I put a <dtml-var REQUEST> as the first line of the 'calling' method and everything then renders correctly with no error. Even the <dtml-var a_dtml_method> renders correctly when it should do so. Any ideas, suggestions ? I'm running Zope 2.1.6 on RedHat Linux Thanks Richard Richard Moon richard(a)dcs.co.uk

That import file is used by Amos' new Zope Tutorial object (you add that via the normal add list). It probably shouldn't blow up if you try to import it normally though - I'll forward this to Amos. > I remember DC promises to add a screen to configure the number of > threads instead of default 7, but I didn't found the screen. > Will it be > added later?

Please test this Zope 2.2 beta 1 ZSQLMethods fix...
by Brian Lloyd 23 Jun '00

23 Jun '00

Hi all, Several folks have reported problems in beta 1 with SQLMethods having authentication problems when trying to call other SQL Methods. I'd like a few intrepid volunteers to try something for me to see if it fixes the problem. I'd like to make a 2.2 beta 2 release tomorrow but I want to make sure this issue is resolved first. Make a backup of the file: lib/python/Shared/DC/ZRDB/DA.py in your current (beta 1) installation and replace it with the DA.py attached to this email, restart and let me know if the problem goes away. Thanks! Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Unfortunately with 2.2.0b2 I have the same problems as in 2.2.0b1 :( On my Win box Zope dont allow add _no one_ objects (eg. Folder), dont allow enter Control Panel if product incorect installed, etc.. Zope 2.1.6 and 2.1.7 (with apropriate patches) works very well. What I am doing wrong or eventually how can I help to avoid this problems ? platform: Win98, Zope2.2.0b2 from official installer, empty (default) Data.fs Eg. if i try to add a Folder that is happend: Error Type: SuperCannotOwn Error Value: Objects cannot be owned by the superuser  Adam Karpierz karpierz(a)itl.pl

image inclusion: empty ALT not the same as no ALT
by J M Cerqueira Esteves 23 Jun '00

23 Jun '00

Greetings I just noticed a problem with the `tag' method: If I insert an image with <dtml-var "some_image.tag (border='0', alt='')"> (nice because `width' and `height' are inserted automatically), I get an <img> element with NO `alt' attribute, instead of an `alt' atribute with an empty string as its value (alt=""). An empty `alt' value is important when using images for which it is best not to insert any alternative text in text browsers (decoration-only or redundant image links, for instance), because the absence of the `alt' attribute may not be equivalent to an empty value. In lynx, for example, the file name of the image (more precisely, the last component of the path in the `src' attribute) is shown (yuck) when no `alt' attribute is supplied. -- jmce: +351 919838775 ~ http://artenumerica.com/ ~ http://artenumerica.org/

The solution always was to add a header to the DTML Method. This was even with a DTML Method that wasn't showing. I always wondered why this would give an error. hth Rik

Re: [Zope] zgadfly and zsql problem
by Adam Karpierz 23 Jun '00

[...] >but it s seems that zgadfly doesn t support da LIKE sql tag! >anyone have an ID ??? >From gadfly FAQ: """ Where is the LIKE predicate? The LIKE predicate for string matching is still not supported at the SQL level. For what it's worth, it is easy to use Python's string matching (regex, re, string.search, etcetera) facilities on the result of a query. Also, for what it's worth, since the gadfly optimizer won't easily be able to optimize for string matching the "by hand" method would essentially be what gadfly would do anyway, without major modifications to the implementation.
