Hi, while working with a Plone 2.0b3 site under Zope 2.7/Python 2.3.2 I encountered the following error when I am trying to render a ZPT: Error on the console: Traceback (most recent call last): File "/develop/sandboxes/tracker/Zope/lib/python/zExceptions/ExceptionFormatter. py", line 157, in formatLine result.extend(self.formatSupplement(supp, tb)) File "/develop/sandboxes/tracker/Zope/lib/python/zExceptions/ExceptionFormatter. py", line 105, in formatSupplement extra = self.formatExtraInfo(supplement) File "/develop/sandboxes/tracker/Zope/lib/python/zExceptions/ExceptionFormatter. py", line 231, in formatExtraInfo extra = getInfo(1) File "/develop/sandboxes/tracker/Zope/lib/python/Products/PageTemplates/TALES.py ", line 274, in getInfo s = pprint.pformat(data) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 58, in pformat return PrettyPrinter().pformat(object) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 109, in pformat self._format(object, sio, 0, 0, {}, 0) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 127, in _format rep = self._repr(object, context, level - 1) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 191, in _repr self._depth, level) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 203, in format return _safe_repr(object, context, maxlevels, level) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 246, in _safe_repr vrepr, vreadable, vrecur = saferepr(v, context, maxlevels, level) File "/opt/python-2.3.2/lib/python2.3/pprint.py", line 286, in _safe_repr rep = `object` File "/develop/sandboxes/tracker/Zope/lib/python/ZPublisher/HTTPRequest.py", line 1291, in __repr__ return "<%s, URL=%s>" % (self.__class__.__name__, self['URL']) File "/develop/sandboxes/tracker/Zope/lib/python/ZPublisher/HTTPRequest.py", line 1210, in __getitem__ raise KeyError, key KeyError: 'URL' Message in the error_log/browser Traceback (innermost last): * Module ZPublisher.Publish, line 161, in publish_module_standard * Module ZPublisher.Publish, line 125, in publish * Module Zope.App.startup, line 205, in zpublisher_exception_hook * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 252, in __call__ * Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec * Module Products.CMFCore.FSPageTemplate, line 189, in _exec * Module Products.CMFCore.FSPageTemplate, line 122, in pt_render * Module Products.PageTemplates.PageTemplate, line 96, in pt_render <FSPageTemplate at /plone/pcng_issue_view used for /plone/PloneCollectorNG.2003-11-10.6925493633/20> * Module TAL.TALInterpreter, line 189, in __call__ * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 663, in do_useMacro * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 408, in do_optTag_tal * Module TAL.TALInterpreter, line 393, in do_optTag * Module TAL.TALInterpreter, line 388, in no_tag * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 663, in do_useMacro * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 686, in do_defineSlot * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 408, in do_optTag_tal * Module TAL.TALInterpreter, line 393, in do_optTag * Module TAL.TALInterpreter, line 388, in no_tag * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 663, in do_useMacro * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 408, in do_optTag_tal * Module TAL.TALInterpreter, line 393, in do_optTag * Module TAL.TALInterpreter, line 388, in no_tag * Module TAL.TALInterpreter, line 233, in interpret * Module TAL.TALInterpreter, line 459, in do_setLocal_tal * Module Products.PageTemplates.TALES, line 220, in evaluate * Module Products.PageTemplates.ZRPythonExpr, line 48, in __call__ __traceback_info__: request.RESPONSE.setHeader('Content-Type', 'text/html;charset=%s' % charset) * Module Python expression "request.RESPONSE.setHeader('Content-Type', 'text/html;charset=%s' % charset)", line 1, in <expression> * Module ZPublisher.HTTPRequest, line 1216, in __getattr__ AttributeError: RESPONSE (Also, an error occurred while attempting to render the standard error message.)
