Hello, I just installed sqlsession 0.2.9 in my NT with zope version 2.1.6, and I had created the table in Gadfly according to the given sql schema. When I try to load the Session into my page, it just work for the first time, after that I got an error like this : Zope Error Zope has encountered an error while publishing this resource. KeyError Sorry, a Zope error occurred. and when I view the source, I got this : <!-- Traceback (innermost last): File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 214, in publish_module File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 179, in publish File E:\MYBOOK~2\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 165, in publish File E:\MYBOOK~2\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: index_html) File E:\MYBOOK~2\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: index_html) File E:\MYBOOK~2\lib\python\OFS\DTMLDocument.py, line 166, in __call__ (Object: index_html) File E:\MYBOOK~2\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: index_html) File E:\MYBOOK~2\lib\python\OFS\DTMLMethod.py, line 146, in __call__ (Object: standard_html_header) File E:\MYBOOK~2\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: standard_html_header) File E:\MYBOOK~2\lib\python\Products\SQLSession\SQLSession.py, line 294, in __call__ (Object: Session) File E:\MYBOOK~2\lib\python\Shared\DC\ZRDB\DA.py, line 424, in __call__ (Object: sqlSessionLookup) File E:\MYBOOK~2\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: <string>) File E:\MYBOOK~2\lib\python\Shared\DC\ZRDB\sqltest.py, line 179, in render (Object: zsession) KeyError: zsession --> Is this cause by the wrong database field name or what ??
