Hello All,

I'm trying to upgrade a Zope 2.0.1 site to 2.1.2. I used http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO <http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO> as a reference guide. Everything seems to have worked fine except for a Z class that I had previously created. I created a new product as described in http://www.zope.org/Members/lstaffor/zProperties <http://www.zope.org/Members/lstaffor/zProperties> After performing the upgrade, the product is no longer functional.

As an alternate route, I tried exporting the product to a .zexp file. That worked fine, but I was then unable to import the file into the new Zope instance.

Is there an upgrade path for Z Classes that I am as yet unaware of? I still consider myself a newbie. Any ideas? Thanks in advance for any help provided.

Hmm, I move ZClass-based products back and forth between 2.0.1 and 2.1.2 all the time. A couple of possible gotchas: * When you export the product DO select it in the Products list and push the "Export" button, but DON'T select the "As XML" checkbox (Zope can't reimport the file as XML). * If your ZClasses have ExternalMethods, then you need to move them as well. On 2.0.1, these have to be in the $INSTANCE_HOME/Extensions directory; in 2.1.2, you can create a directory for your Product under $INSTANCE_HOME/lib/Python/Products, and then put the Python file into the Extensions subdirectory under it -- you can then refer to it as "FooProduct.SomeModule" in the ExternalMethods. * If your ZClass inherits from another non-standard ZClass, you need to install the base class first. Hope this helps! Tres. -- ========================================================= Tres Seaver tseaver@palladion.com 713-523-6582 Palladion Software http://www.palladion.com
