After posting this error yesterday and getting no reply, I decided to verify that it was not due to something left over from a previous installation. I dumped my entire installation into another directory and untarred Zope-2.0.0a2 into an empty directory. Then did the following: $ python w_pcgi.py $ ./start Upon entering the root manage view, the first thing I noticed was the QuickStart which I had never seen before. I then went to Control_Panel/Database/manage_cacheParameters and no error. Next I tried Control_Panel/Database/manage_cacheGC and again no error. At that point I thought I had solved the problem and backed out to Control_Panel when I noticed there was no restart button. Remembering that the Restart button was part of ZServer, I shutdown the Zope process and went back to look at the start file. There I changed python serve.py to python z2.py and restarted. Now upon entering the root manage view, the first thing I noticed was QuickStart was no longer visible. I proceeded to the Control_Panel/Database/manage_cacheParameters and there was the TypeError exception again. I backed out and tried Control_Panel/Database/manage_cacheCG and again there was the TypeError exception. Here again is the traceback output which is exactly the same for both cases. exceptions.TypeError Traceback (innermost last): File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 255, in publish_module File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 161, in publish File /opt/www/zope/lib/python/ZPublisher/mapply.py, line 154, in mapply (Object: cacheParameters) File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 98, in call_object (Object: cacheParameters) File /opt/www/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/App/CacheManager.py, line 109, in cache_length (Object: Control_Panel) File /opt/www/zope/lib/python/ZODB/DB.py, line 272, in cacheSize TypeError: too many arguments; expected 1, got 2 The problem starts in App/CacheManager in cache_length() where it determines we are not using BoboPOS2 and tries to return db.cacheSize(). When using serve.py, we are using BoboPOS2 and thus the error in ZORB/DB.py is not encountered. At this point, I have no idea how to go about solving the problem. I have looked at the code and cannot immediately find anything wrong with it, but as I stated before, I have only been using Python for a few months so I may be overlooking something. Also, why does QuickStart show up using BoboPOS2 and not with ZORB3? Is anyone else using ZServer and getting these errors or am I the only one who seems to have this problem? Regards, Jarrod Kinsley
