Hi guys, I've got an issue here, the following traceback can be seen after several users modify and view the same object in a short (2-3) minute period. I've tried recataloging the objects but that doesn't help either; this error is seen every time.. Site Error An error was encountered while publishing this resource. KeyError Sorry, a site error occurred. Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/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: api) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/zope/lib/python/Products/warp_framework/object_manager_inter face.py, line 88, in index_html (Object: api) File /usr/local/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: object_manager_index) File /usr/local/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: object_manager_index) File /usr/local/zope/lib/python/App/special_dtml.py, line 244, in _exec (Object: object_manager_index) File /usr/local/zope/lib/python/DocumentTemplate/DT_In.py, line 770, in renderwob (Object: get_meta_types) File /usr/local/zope/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: get_number_of_objects(meta_type=_['sequence-item'])) (Info: get_number_of_objects) File <string>, line 0, in ?
