I have about 300 folder objects in my ODB. Running 2.1.6 on Linux. One (and maybe more) of the folders are not accessable by top-level admin or manager. ... Error Type: TypeError Error Value: attribute-less object (assign or del)

TraceBack: Traceback (innermost last): File .... /usr/local/Zope-2.1.6-src/lib/python/Products/ZDBase/ZDiscussions.py, line 195, in manage_beforeDelete (Object: 971638688) TypeError: attribute-less object (assign or del) Apparently, you have a broken "ZDiscussion" installation.

I think, you have (at least) two options: 1. install a working ZDiscussion product 2. if this is impossible: empty the current definition of "manage_beforeDelete" in "Products/ZDBase/ZDiscussions.py" line 195 (replace its content by "pass"). Enter your folder, delete the ZDiscussion objects, and then get rid of ZDiscussion altogether. Dieter
