I was thinking that acquisition would provide "standard_xml_header/footer" wrapper documents, which would call out the location-appropriate style sheet, a la standard_html_header. So the "default_xml" document could look like: <dtml-var "name=standard_xml_header"> <dtml-var "name=xml_body"> <dtml-var "name=standard_xml_footer"> -- ================================================================================ Tres Seaver tseaver(a)palladion.com http://www.palladion.com Palladion Software Houston, Texas, USA 713-523-6582

Most python binary distirbutions do not come with the header files and development stuff, you either need to install the python source or the development package. I don't know how BSDI handles packaging issues. Better just to install Python 1.5.2 from the source. -Michel

I've had problems with infinite looping with that hook that we fixed in 2.0b1. You might not be using what we would consider the 'right' code. In my particular situation, I had an object that defined an on delete style hook that was broken (because I broke the python below it), and thus rendered unpickleable, however, I could send Zope into an infinite loop by trying to delete that object, which caused it to acquire it's containers on delete hook, which tried to notify all it's subobjects of the pending delete, which caused the broken object to acquire it's containers on delete hook, which caused it to notify all it's subobjects of the pending delete..... Use the debugger to recreate your request in the python interpreter. This will allow you to break it with a control-c to see where it's looping. -Michel

Q: how to tell property types from manage's Properties tab?
by Joe Grace 04 Aug '99

04 Aug '99

Hi, quickie Q I'm hoping. How to tell property types from manage's Properties tab? I'm looking at the DTML demos which are very useful and notice that there are a variety of types for properties. Is there an easy way through the management tabs (or alternatively, I guess) to get the type information for the various existing properties? Thanks, = Joe "Newbie to Zope" Grace =

Look at that entry in the Help System. Oh it's even more fun than that. A lot of it is now dynamically registered, rather than sniffed out, so things in the help system need a major refactoring. We had a meeting 2 days ago to discuss this, and the decision was that we wanted to fix the online help system, but we're not sure it'll happen before the RELEASE of 2.0. Until then, unfortunately, a lot of it is in the code. Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli(a)digicool.com http://www.digicool.com

Agreed. (Although nothing would prevent you from using DTML to output different style-sheet headers depending on the environment.) Acquisition -- something like http://myserver/HighBandwidthHtml/MyDocument perhaps -- would be fine, but how to specify a default style sheet? There might be cases where I would want user-selectable style sheets through cookies, or a site-wide default style sheets without the need to explicitly state it in the URL. -- Alexander Staubo http://www.mop.no/~alex/ "Elvis skipped around the car and threw open the trunk.

Zieve.... one way to sort ZClasses dynamically...
by Steve Spicklemire 04 Aug '99

04 Aug '99

Get it at: http://www.zope.org/Download/Contrib/Zieve.tgz from the README: Zieve 0-0-1 Zieve is a (beta) Z-subclassable class that assists in sorting ZClasses in various ways. To use Zieve... unpack the tgz file in the zope home folder. Then start Zope and create a ZClass with Zieve as a base class. Then put an instance of this ZClass where you can reach it from your folders of other ZClasses. Here is some DTML from a DTMLMethod that uses a zclass derived from Zieve to do some sorting... This displays a table heading with links that dynamically resort the table according to which link was clicked last. The secondary, tertiary, ...etc keys are remembered from prior clicks.... ----------------------------------------------------------------------  <h2></h2> <br>    <center><table> <tr> <td><a href="theZieve/setSortPrimary?key=name">name</a></td> <td><a href="theZieve/setSortPrimary?key=color">color</a></td> <td><a href="theZieve/setSortPrimary?key=birthstone">birthstone</a></td> <td><a href="theZieve/setSortPrimary?key=number:int">number</a></td> </tr>   <tr> <td></td> <td></td> <td></td> <td></td> </tr>   </table></center>   Sorry.. there are no objects to sort..   ---------------------------------------------------------------------- steve(a)spvi.com

incomplete Help System
by Alex Rice 04 Aug '99

04 Aug '99

Just posted to Collector: The Help Tab in the 2.0 series Zopes has incomplete information. For instance, in Object Reference/'Folder' there are only 3 methods listed. However, on http://www.zope.org/HelpSys/, 'Folder' has 38 methods listed. Is there any way I can update this information in my current Zope installation?
