[Zope] Folderisch ZClasses import into 2.6.0 broken?

[Gidon Friedman]

i'm writing the answer to my own question to the list for the records:

the Interface.iclass reference is in the meta_types section of the 
ZClasses. meta_types defines a list of dictionaries that discribe the 
allowed objects of the folderish ZClass. so you just have to delete the 
meta_types tuple. this is easy to accomplish with the Subobjects-Tab of 
the ZClass, submitting an empty list.

Then export the ZClasses, import them in the new site and then recreate 
the meta_types again by hand. et voila, your old ZClasses-Zombies are 
back to live.

But then you remember sombody told you to use Python Base Class for the 
ZClasses, don't you? ;-)

take care
