Hi, The following code: objects = map(lambda b: b.getObject,brains) Results in: Error type: Unauthorized Error value: __len__ File E:\Zope\current\Products\CMFCore\FSPythonScript.py, line 187, in _exec (Object: index_html_postings) (Info: ({'script': <FSPythonScript instance at 01BB2C20>, 'context': <SwishdotSite instance at 01C09950>, 'container': <SwishdotSite instance at 01C09950>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 5, in index_html_postings File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 204, in __careful_map__ (Object: <lambda>) File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 273, in __getattr__ File E:\Zope\2379B4~1.2\lib\python\Products\PythonScripts\Guarded.py, line 152, in __careful_getattr__ ...and yet the following code: objects = [] for brain in brains: objects.append(brain.getObject()) ...works fine. This is on Zope 2.3.2, is it a bug? cheers, Chris
