I can't seem to create a default view of my ZClass. I create a document called "index_html". In this I refer to both standard_html_header and standard_html_footer. Both of these have problems when I try render an instance of my class. One gives an authentication error when trying to access "id". The other gives Error type: AttributeError Error value: __call__ <!-- Traceback (innermost last): File D:\PROGRA~1\PROVIS~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\PROGRA~1\PROVIS~1\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\PROGRA~1\PROVIS~1\lib\python\Zope\__init__.py, line 201, in zpublisher_exception_hook (Object: CatalogAware) File D:\PROGRA~1\PROVIS~1\lib\python\ZPublisher\Publish.py, line 165, in publish File D:\PROGRA~1\PROVIS~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: index_html) File D:\PROGRA~1\PROVIS~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: index_html) File D:\PROGRA~1\PROVIS~1\lib\python\OFS\DTMLDocument.py, line 166, in __call__ (Object: index_html) File D:\PROGRA~1\PROVIS~1\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: index_html) File D:\PROGRA~1\PROVIS~1\lib\python\OFS\DTMLMethod.py, line 141, in __call__ (Object: standard_html_header) File D:\PROGRA~1\PROVIS~1\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: standard_html_header) File D:\PROGRA~1\PROVIS~1\lib\python\DocumentTemplate\DT_With.py, line 148, in render (Object: news.news_items) File D:\PROGRA~1\PROVIS~1\lib\python\OFS\DTMLMethod.py, line 141, in __call__ (Object: ViewNewsItems) File D:\PROGRA~1\PROVIS~1\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: ViewNewsItems) File D:\PROGRA~1\PROVIS~1\lib\python\DocumentTemplate\DT_With.py, line 132, in render (Object: news_items) AttributeError: (see above) These methods have no problem with other documents. Is there something I'm doing wrong? Also, how do I change the manage screen for a property sheet. It gives me a default view but what if I want to change it?
