I've just switched to 2.7 from 2.6.3 and everything seems to work well except for one rather bizarre event:
I have a specific content type that can't be viewed, accessed or otherwise used/viewed in any way without sending Zope into an infinite loop!
Here's the error I get:
Zope Error Zope has encountered an error while publishing this resource.
Error Type: RuntimeError Error Value: maximum recursion depth exceeded ... Module ZPublisher.Publish, line 94, in publish Module Zope.App.startup, line 257, in recordMetaData Module OFS.SimpleItem, line 333, in getPhysicalPath Module OFS.SimpleItem, line 76, in <lambda> Module OFS.SimpleItem, line 310, in getId Module OFS.SimpleItem, line 76, in <lambda> Module OFS.SimpleItem, line 310, in getId Module OFS.SimpleItem, line 76, in <lambda> Module OFS.SimpleItem, line 310, in getId ...
This is a bug in "OFS.SimpleItem.Item_w__name__". In its base class, "__name__" is defined as "ComputedAttribute(lambda self: self.getId())" and it defines "getId()" to return "self.__name__". Apparently, this is an infinite recursion. Please file a bug report to "http://www.zope.org/Collectors/Zope". You can fix this problem by giving "Item_w__name__" a default class level attribute or "__name__ = ''". You can work around the bug by assigning an "id" for your object with its "_setId" method (this overrides "__name__"). -- Dieter
