Hotfix_2000-12-08 and MailHost
by Salvatore Sciacco 30 Dec '00

30 Dec '00

Hello, after the installation of the 12-08 fix you can't add MailHost anymore. I see that the product use a "legacy" method. Any solution? Thank you in advance. -- Best regards, Salvatore Sciacco mailto:sas@prometeus.net

Example activity-explicit workflow system
by Albert Boulanger 29 Dec '00

29 Dec '00

For those interested in workflow systems and workflow within Zope, the following workflow system may be useful to try out. It models workflow steps explicitly and a workflow becomes a graph with a visual editor. I have been meaning to send along some resources in this area I have been accumulating. The Endeavors group at UCI developed this and the peer-to-peer system they built, Magi, is now at www.endtech.com as open source. They are still developing the workflow product but an early prototype you can download and play with is at: http://www.ics.uci.edu/pub/endeavors/endeavors.html See also the papers and the web-based workflow thesis at: http://www.ics.uci.edu/pub/endeavors/docs/papers/ There was discussion of graphical system to present workflow. I have looked at several, including the At&T stuff. When I have time, I will send a separate email with some that I have found. One thing to look at which is ActiveX based at the moment is http://www.lassalle.com/ A general purpose Flowcharting/Diagramming ActiveX control. I am very interested in a general, fairly full featured workflow system on top of Zope as opposed to using an external workflow product for a fundamental reason. While one could come up with a way of getting what I need with an external system, it would be messy. I need workflows to be explicit and versioned. We make use of ZODB to version content that end users generate. We don't make use of Zope's versioning but use or own hierarchical version tree which is easy to do in Zope. End users generate new workflows and revisit past workflows. The user sees this versioning as notebook pages using a scientific notebook metaphor. It is much cleaner to use ZODB and ZPublisher to do all this instead of having a version tree in Zope and a bunch of correspondences to outside objects in an external workflow system. Thus, there is a lot of value in having a fairly general workflow system whose representation and publishing uses ZODB and ZPublisher. There seems to be a principle here on how to layer systems correctly on top of ZODB and ZPublisher or any persistant-object web publishing system. One way is very clean and simple and other ways are nightmares. Regards, Albert Boulanger aboulanger(a)vpatch.com

I'm no zopista but I think the problem has to do with the standard error methods not being tied in directly to the object database. There are two files: /lib/python/ZPublisher/HTTPResponse.py /lib/python/OFS/Application.py that contain error pages hard coded in. you get the HTTPResponse.py code for errors like: 403: 'Forbidden', 404: 'Not Found', 405: 'Method Not Allowed', stuff like that. This error code is not parsed like normal dtml and so you can't simply replace it with: """<dtml-var standard_error_message>""" I think this is because these are standard error codes that have to do with the web server and they must work even if the object database doesn't. There must be a more detailed reason why these errors aren't connected to the db, but someone else will have to answer that one. :) jason __________________________________________________ Do You Yahoo!?

Re: [Zope] How to make two racks work under one specialist?
by Dirksen 29 Dec '00

29 Dec '00

Hi Steve, It works! Thank you. Still there's a couple of things to be cleared. What's the use of 'otherwise' clause? And is it true that the 1st 'with' clause fails, the whole skinscript process fails (so one 'with' clause is all one skinscript can put up with)?

mynetscape-like product
by albert boulanger 29 Dec '00

29 Dec '00

Dose anyone have a product or modification to the user's page in the PTK to behave like the user customizable layout you get at sites like mynetscape.com? This would work with RSS and OCS syndication sources (as well as others). Regards, Albert Boulanger aboulanger(a)vpatch.com

There is a (low traffic) mailing list especially for Z-Commerce (to be found via zope.org) Look into its archives. You will find a thread that discusses 2 or 3 approaches. Dieter

As the message tells you, there is another Zope process accessing your "var/Data.fs". Are you sure, that your ZServer started Zope is really stopped? > python z2.py > .... > ImportError: No module named ZServer Do not start Zope in this way, use the "start" script. This script defines some environment variables (such as PYTHONHOME) before it executes "python z2.py". These environment variables are necessary to find Zope's infrastructure. Dieter
