As the current product lead for the PTK, and a DC consultant who uses it every day in developing software for customers, I wouldn't say that your statement is, perhaps, misleading. While I'm not the person who negotiates support contracts for DC, I do know that DC sees the PTK as a key element of our future growth plans. In the meantime, most people get their support fo using the PTK from the place they get support for using Zope: right here on the lists: mailto:zope-ptk@zope.org http://lists.zope.org/pipermail/zope-ptk http://lists.zope.org/mailman/listinfo/zope-ptk (I watch the PTK tracker, as well).

Ok, I'm bringing zope.org down and back up in read-only mode. Then I am going to copy the data.fs over, start the new server again, and proxy the old zope to the new one. Enjoy! ~ethan

You should look at the source of your "class2_add", especially the constructor that creates the object. I expect, that you use "class2.createInObjectManager" to create your "class2" instance. "C.createInObjectManager" usually uses "C.aq_parent" to determine the object manager where the new C instance should be created (unless it has a "Destination" attribute). This should be your "class1" instance "instance1", more precisely, an acquisition wrapper for it. There are two possibilities: 1. for reasons, I do not understand, "class2.aq_parent" is not "instance1" 2. it is "instance1", but "instance1" does not have a "_setObject" method, i.e. "class1" is not derived from ObjectManager.

Digital Creations is considering offering Zope classes for the European market with perhaps two classes in the Springtime in 2001. We are asking for your input on: 1) are there any students interested in attending? 2) suggestions for class locations and dates? 3) price has not been set yet and may vary according to location costs. 4) most likely the classes would be taught in English 5) what other languages? 6) are there qualified multi-lingual Zope instructors?

I would look at 'ZTopics.Topic._contentsSet()' to see what it is trying to do with the catalog. I would log also log this as a PTK issue: http://www.zope.org/Products/PTK/Tracker rather than in the Collector (I don't believe it is a Zope issue, per se).

Place a DTML method(!) "index_html" high in your Zope hierarchy with the following code: <dtml-var index.html> >From then on, you can happily create "index.html" below that point in the hierarchy. It will be used as the default folder view. In fact, "index_html" is used but that redirects to "index.html". Dieter

paul_s_johnson(a)urscorp.com writes: > ... passing parameters to Z SQL methods ... This is an FAQ. You already know the searchable list archive at NIP? Z SQL methods do *NOT* take parameters from the DTML namespace. They only look at "REQUEST". You have two options: 1. put your parameters into the REQUEST object: <dtml-call "REQUEST.set('myparam', myparam_value)"> .... 2. call the Z SQL method with explicit parameters: <dtml-in "myMethod(myparam= myparam_value, ....)"> Dieter

"aq_parent". It is an attribute, not a method. Dieter
