[Zope-dev] ZCatalog Error in 2.4.0b2

[Chris Withers]

Hi,

I'm doing something simple:

return catalog.searchResults(sort_on='dateofpublication')

...and getting something horrible:

Error Type: TypeError
Error Value: unsubscriptable object

  File
/usr/local/zope/2.4.0b2_base/lib/python/Products/PythonScripts/PythonScript.py,
line 362, in _exec
    (Object: latest_articles)
    (Info: ({'script': <PythonScript instance at 8cb0048>, 'context':
<Folder instance at 85996a8>, 'container': <Folder instance at
85996a8>, 'traverse_subpath': []}, (), {}, None))
  File Script (Python), line 4, in latest_articles
    (Object: guarded_getitem)
  File /usr/local/zope/2.4.0b1_base/lib/python/Products/ZCatalog/Lazy.py, line
94, in __repr__
  File /usr/local/zope/2.4.0b1_base/lib/python/Products/ZCatalog/Lazy.py, line
223, in __getitem__
TypeError: (see above)

What's going on?

cheers,

Chris
