Re: [Zope] Changing Zclass Base Classes
Hmm... When you say "they are somehow broken", you mean they show up >in the management interface as broken objects?
No, they are ok.
How did you change the base classes? Did you use the hold-on-to-the-seat-of-your-pants-unsupported method, or did you >create new a new ZClass?
I renamed my old class for class_temp and created new ones with same name, same properties, etc. I dont no whats wrong :( Júlio ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Look at your ZClass in the management view. Look under the "basic" tab. You should find the field "class id". Its value will be a string such as "2nBsaF/GgaN176QFvINZIw==". This value links instances of the ZClass to the ZClass definition. It could be that you didn't alter this property in your new ZClass. Would that alone work? I don't know -- never tried it!

Yep... That's the problem. Julio, you can go into the class_temp Basic tab, copy the class ID from there (and then change it). Then, replace the class ID in your new ZClass. Note that this will break any new instances you created (you may want to delete those first). I think the howto mentioned below has the step-by-step procedure.
