What if you change : <updated tal:content="python:obj.modified().HTML4()">2000-01-01T12:00+00:00</updated> to : <updated tal:content="python:obj.modified.HTML4()">2000-01-01T12:00+00:00</updated> ? (just a guess, because it says that obj.modified already is a DateTime instance)

Hi

Been following this turorial at:

http://worldcookery.com/files/ploneconf05-five/index.html

Using Plone 3.0.6. and Zope 2.10.5 and trying to view http://localhost:8080/portal/news/atom.xml

leads me to the below error. Plone 3 thing?

Module zope.tales.tales, line 696, in evaluate - URL: index - Line 22, Column 3 - Expression: <PythonExpr (obj.modified().HTML4())> - Names: {'container': <ATBTreeFolder at /portal/news>, 'context': <ATBTreeFolder at /portal/news>, 'default': <object object at 0x008BB528>, 'here': <ATBTreeFolder at /portal/news>, 'loop': {u'obj': <Products.PageTemplates.Expressions.PathIterator object at 0x082FFB10>}, 'nothing': None, 'options': {'args': (<Products.Five.metaclass.SimpleViewClass from C:\Enfold\Products\FiveFeeds\atom.pt object at 0x082FFD50>,)}, 'repeat': <Products.PageTemplates.Expressions.SafeMapping object at 0x0864EE68>, 'request': <HTTPRequest, URL=http://localhost:8080/portal/news/atom.xml>, 'root': <Application at >, 'template': <ImplicitAcquirerWrapper object at 0x082FFDD0>, 'traverse_subpath': [], 'user': <PropertiedUser 'michael'>, 'view': <Products.Five.metaclass.SimpleViewClass from C:\Enfold\Products\FiveFeeds\atom.pt object at 0x082FFD50>, 'views': <zope.app.pagetemplate.viewpagetemplatefile.ViewMapper object at 0x082FF990>} Module zope.tales.pythonexpr, line 59, in __call__ - __traceback_info__: (obj.modified().HTML4()) Module <string>, line 0, in ?
