Hi, i have a made a product with a zclass in zope 2.3.4, created with the zclass constructor methods. It worked fine. Now we've upgraded to zope 2.4.3. When i try to add an instance of this product i get the following error: <!-- Traceback (innermost last): File /usr/local/Zope-2.4.3-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/Zope-2.4.3-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: Einstiegstext_container_factory) File /usr/local/Zope-2.4.3-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.4.3-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: Einstiegstext_container_add) File /usr/local/Zope-2.4.3-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: Einstiegstext_container_add) File /usr/local/Zope-2.4.3-src/lib/python/OFS/DTMLMethod.py, line 199, in __call__ (Object: Einstiegstext_container_add) File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 546, in __call__ (Object: Einstiegstext_container_add) File /usr/local/Zope-2.4.3-src/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: Einstiegstext_container.createInObjectManager(REQUEST['id'], REQUEST)) File /usr/local/Zope-2.4.3-src/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: Einstiegstext_container.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 2, in f (Object: guarded_getitem) NameError: (see above) --> I have tried exporting and reimporting the product, but no change in behaviour. The weird thing is, that there are some subfolders where adding an instance of this product works without problems. I have checked the permissions and these subfolders have no special settings. If it had to do with permission I would expect any kind of unauthorized error or sth related instead of this name error problem, or am i wrong? I have noticed that other Zopers have experienced this behaviour too, did you solve the problem? Anybody else who knows why this is happening?
