It _looks_ like you have a "broken" object in your top-level Folder. "Broken" objects are created when Zope has a problem unpickling an object (usually because the add-on product that defines the class of the object is missing). Are you sure that you got all of your add-on products installed (and any other dependencies like external methods) copied to the beta install? Alternatively, it is possible that one of your add-on products is incompatible somehow with the beta (if it can't import correctly, for example, then objects created from the product would be broken). One way you could probably test this theory: o shut down your beta installation o cd to your lib/python directory and crank up a Python prompt o do 'import Zope'. Look for any tracebacks (though the product import process will likely consume exceptions when trying to import products). o for each 3rd party product in lib/python/Products, try to do: 'import Products.xxx' where xxx is the product package name. If a product cant be imported, you should get a traceback for it (please post it if you get one). Hope this helps!

Zope on NT - port problem
by - - 14 Jun '00

14 Jun '00

Hi all How do I customise the port number that Zope installs to? I'm running NT and there is already a service running on the default port 8080. Also, is anyone using dreamweaver and zope? I want site designers to use the tools they already have and then content management etc will be done with zope. Thanks .wes ----------------------------------------------- FREE!

Zope Weekly News June 14th
by ethan mindlace fremen 14 Jun '00

14 Jun '00

LinuxTag, the Open Source Conference, Launch of Zope 2.2.0b1, a Docs Wiki and much Documentation work, PTK gains steam, Guido's time machine stolen, Improved Products page and more! The opinions expressed in Zope Weekly news are solely the authors', and not the opinions of Digital Creations, The Zope Community at-large, or the Spanish Inquisition. The Zope Weekly News now has a "permanent home", http://www.zope.org/Documentation/ZWN. And Now For Something Completely Different: Coming Events LinuxTag There will be a Zope booth at the "LinuxTag", http://www.linuxtag.de in Stuttgart, Germany from June 29th to July 2nd. In addition to the booth that will be there for the whole conference, there will be 2 rooms available for talks and discussions on the business day, Thursday 29th. There will not be an additional charge for the two rooms on buisness day. We are still looking for people who want help organizing the conference, give some talks and attend the booth. Generally, it would also be great to know who is planning to be at the conference. Please send feedback to "Stephan Richter", mailto:srichter@digicool.com See "Zope at Linuxtag", http://www.zope.org/Members/Linuxtag/ for the most up-to-date information. The Open Source Convention This "enormous convention", http://conferences.oreilly.com/oscon2000/ hosted by O'reilly, is shaping up to be pretty interesting. Aside from the State of Python, given by Guido von Rossum, there's also going to be a "talk on the CERT Advisory", http://www.oreillynet.com/pub/w/evening_events.html about cross-site scripting, a web-wide security issue that the Zope Community was among the first to begin implementing security policies for: they'll land with zope 2.2. Zope is going to be at the conference in force, with: - Paul "opening eyes to the Zope-Mozilla initiative", http://www.oreillynet.com/pub/e_sess/853 - Ryan telling the world "you can have web IMAP and collaboration", http://www.oreillynet.com/pub/e_sess/725 - Christopher, as always, concentrating on the "edification of the community", http://www.oreillynet.com/pub/w/python_tutorials.html Documentation -- by Amos Lattier This Week * We've released the Docs Wiki http://www.zope.org/Wikis/Docs This is your source for information on official Zope documentation. You can find out about all our projects including their status and timelines. You can also see what Amos, Michel and Stephan are doing each week. Plus, since it's a wiki you can add your comments. * The bulk of this week's work will be spent trying to get the online docs ship shape for Zope 2.2 final. Mike is finishing up the API docs, Amos is working on the help system framework and tutorial and Stephan is working on the management help content. * Mike is working with O'Reilly this week to clarify the status of his book. If all goes well we should have a definitive answer on making it official Zope documentation by the end of the week. Next Week * Next week will be spent finishing any bits that need finalizing for Zope 2.2 that we don't finish this week. * Hopefully next week we can begin making Mike's book public. Zope Status -- by Brian Lloyd Summary We finally beat the todo list and got the 2.2 beta 1 release "out the door", http://www.zope.org/Products/Zope/2.2.0b1 (and there was much rejoicing!). Last week highlights 7 more collector issues were closed last week, and the remaining items on the todo list for 2.2 beta 1 were knocked out. The needed hooks for non-invasive virtual hosting support were added, as well as better Undo handling, several catalog fixes and some long overdue fixes to the way that HTTP HEAD requests are handled that should make Zope more friendly to various spidering tools. This week's good-buddies-of-the-core: o Chris Withers and others for forcing some action on the HEAD issue o Toby Dickenson and Butch Landingin contributed fixes for ZCatalog o tazzzzz sent a patch to un-screw what I screwed up last time I worked on MailHost :^) Next week Next week we'll be absorbing feedback on the beta release and planning for final. More importantly, work will begin in earnest on the "opening the development process" initiative. I hope to get a basic "Zope core development"- focused area set up, publish the draft Zope roadmap for comment and start working out some post-2.2 plans. This week in the PTK Community -- by Tres Seaver * David Brown, author of "Zope Fish":http://zopefish.weblogs.com/ZopeFishRelease, agreed to join TeamPTK. Welcome! * We arrived at protocol for gaining consensus on proposed changes: - Create a tracker issue embodying the proposal (which then emails the list). - Discuss the proposal in email, copying significant arguments to the tracker. - Finally, one TeamPTK member accepts the item, makes the changes, and posts the patch/update. - After a final "speak now or forever hold your peace" interval, TeamPTK member checks in changes. * Bill Anderson found a workaround for the problem of DTML methods "losing" other methods inside the portal: <URL http://lists.zope.org/pipermail/zope-ptk/2000-June/000940.html> * Dan Pierson checked in his patches integrating the PTK with the new LoginManager: <URL http://lists.zope.org/pipermail/zope-ptk/2000-June/000937.html> * Dan also proposed fixing "Discussable" items such that they *always* display their discussion: <URL http://www.zope.org/Products/PTK/Tracker/93> * Dan Pierson posted a tracker issue describing the difficulty of customizing the display of PortalContent objects: <URL http://www.zope.org/Products/PTK/Tracker/94> * Tres Seaver created a somewhat terse How-To on creating PortalContent classes as ZClasses: <URL http://yyy.zope.org/Products/PTK/ZWiki/CreatingAPortalContentZClass> * Tres also wrapped up the "vision" statement for the PTK-NG: <URL http://www.zope.org/Products/PTK/ZWiki/OnceAndFuturePTK> * Phillip Eby delivered a wonderful "motivation" piece for the ZPatterns meta-framework he and Ty Sarna have been building (and which underlies LoginManager): <URL http://lists.zope.org/pipermail/zope-dev/2000-June/005323.html> * Shane Hathaway replied with a nice "file clerk" analogy for the ZPatterns: <URL http://lists.zope.org/pipermail/zope-dev/2000-June/005352.html> * Kevin Dangoor released a new Membership product, which packages the LoginManager in a more "friendly" bundle: http://www.zope.org/Members/tazzzzz/Membership He is asking for testers, with the goal of re-integrating the package with the PTK after a shakeout. * A new discussion on refactoring some of the dependencies between PTKBase and PTKDemo: <URL http://lists.zope.org/pipermail/zope-ptk/2000-June/000962.html> yielded two Tracker issues: <URL http://www.zope.org/Products/PTK/Tracker/96> <URL http://www.zope.org/Products/PTK/Tracker/97> Looking Ahead * Re-integrate Kevin Dangoor's Membership product * Land proposed refactoring of concrete PortalContent and of Discussable decoupling. * Discuss integrating ZPatterns more closely into PortalContent.

File Sub-ZClass
by Nils Jeppe 14 Jun '00

14 Jun '00

Hello fellow Zopians, OK I seem to have further located my problem. In a File ZClass, index_html is used to display the file. But I want my ZClass to have text in the index_html, and display/offer the file for DL in a method, say, download_html. How do I display the File's data? In the Zope Quick Reference I found something called view_file_or_image, but this works only as long as I don't have a custom index_html... Help, anybody? :) Nils -- "Like most of life's problems, this one can be solved with bending." --- Bender

compiling images
by josh on 14 Jun '00

14 Jun '00

Hello, I have been trying to get a collaborative comic book buider made in zope and macromedia director. First I want to say that I have enjoyed working in the open source world of zope so much more than director. Whilst some parts of Director are well documented, others are positively hidden away... completely propritary it seems. Where as here there is a great will to share and distribute knowledge... anyhow that is by the by. (but really appreciated!) My problem is I can't find a good plug-in for Director that lets it export images from shockwave files. They are just 1bit images, so what I can do is export them as a string of 0s and 1s. Could I use zope or PYTHON to convert 25000 0s and 1s into an, er, a PNG file I guess it would have to be. note, I haven't ever written any python, though I here it is very lovely! I guess Director would send it via post to a zope page which would then process it and save a png file. Am I optomistic? josh on

Sharing of the same Data.fs on a separate machine
by Troy Tan Wee Teck 14 Jun '00

14 Jun '00

Currently I have installed 2 machines(machine A and machine B) with Zope 2.1.6 and another machine called C which solely contain the Data.fs which is to be shared by the 2 machines. From what I know whatever changes to the Zope management it will update the Data.fs file (pls correct me if I am wrong). The problem now is these 2 machines are supposed to be on all the time but whenever I did any changes to the Data.fs (example if I add in any dtml methods or whatever in the Zope management) using Machine A. I can only view the new changes that are being implemented on machine A, but when I switch to machine B to view those changes, strangely enough, machine B do not show me the changes that I have already done by machine A since both machine A and B are sharing the same Data.fs from machine C. However, if I do a reboot to machine B, then I will be able to able to view the changes that have been done. What I would like to find out if there is a solution, to enable both machines to view any changes to the Zope management regardless of the Data.fs is modified by either machines. Any kind souls out there, pls enlighten me. Thank you. -- Regards Troy
