Hi! When I copy an folder from Temporary Folder to a normal, persistent folder, after copying ZClasses objects contained in the copied folder become unrecognized: "This object is broken because the unknown product that created it is no longer installed or is installed incorrectly. Please contact the product maintainer for assistance. Note that the data associated with this product has not been lost, and will be accessible again if the product is reinstalled." Of course, the ZClass object is still in the Control_Panel and the source objects display ok. Maybe the problem is that when I moved to Zope 2.7.0. I simply copied my database files from var to the new installation directory. Is there any better way to do this? I would appreciate any ideas. Marcin Wudarczyk http://mar.prv.pl
