This is really strange because the selected value is passed in exactly the same way as the text fields. Maybe, you have a typo in your form field name. If you use as form action the following DTML method, you will see exactly, what the browser (and Zope) have put into the REQUEST object. When used without explicite parameters, the SQL method uses REQUEST to get its parameter values: <dtml-var standard_html_header> <dtml-var REQUEST> <dtml-var standard_html_footer> If this method shows you that the value comes with the right form name, then maybe your problem results from a bug in Zope 2.1.6. Zope 2.1.6 SQL methods first look into their environment and only then into the supplied arguements. There is a patch for this bug in the collector. Dieter

Zope 2.2.0b2 FTP server -- Cannot list directory?
by T.J. Mannos 23 Jun '00

23 Jun '00

I'm having a problem with the Zope FTP server in 2.2.0b2. If I try to get a directory listing, it gives an error saying it can't list the directory. If I try to change directories (even 'cd /'), it tells me it can't find the directory. However, if I know the exact name of the file I want to transfer, it will let me do it. Any ideas? - T.J.

Re: Is DTML a bastardized form of XML, or valid XML?

It's not XML. It's the superposition of two layers: the logic layer and the presentation layer. Ideally, I would like to have a Java applet that parses and splits the DTML management interface into two panels. I'll try to depict my imaginary DTML syntax and editor in ASCII text (I apologize beforehand if I don't succeed... but let me try it). In my opinion, DTML should not be put into XML form, instead, it should be put into Python syntax form. The rest should be handled through a good GUI (Graphical User Interface), with fancy stuff like collapsable panel items. I hope Digicool is doing something like this with their Mozilla project.

Re: Fwd: Re: [Zope] R: [Zope] Invalid Header (0) error
by Mark N. Gibson 23 Jun '00

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.
