Hi: I have a simple schema based on the "Article" ArchExample schema which uses the " RichWidget" for file upload. The product worked fine in Zope2.6.1/Plone1 but does not work in zope2.7.5-final/Plone2.0.5. I am getting a "RuntimeError: maximum recursion depth exceeded" error while trying to view the uploaded file ------- Traceback (innermost last): Module ZPublisher.Publish, line 175, in publish_module_standard Module Products.PlacelessTranslationService.PatchStringIO, line 51, in new_publish Module ZPublisher.Publish, line 132, in publish Module Zope.App.startup, line 204, in zpublisher_exception_hook Module ZPublisher.Publish, line 95, in publish Module Zope.App.startup, line 258, 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> RuntimeError: maximum recursion depth exceeded (Also, an error occurred while attempting to render the standard error message.) ----- END Traceback I googled and found that it is zope bug (issue# 1253, URL:http://www.zope.org/Collectors/Zope/1253). I also, found similar this error is documented in Bug#928693 & 909894 in Plone2. Diater suggested a workaround (in zope Issue# 1253) which I don't quite understand being a python newbie. From Dieter:
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 <http://www.zope.org/Collectors/Zope/1253/>".
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__").
Could someone please tell me where/what code I should make this changes? I posted this before in Plone list but did not get any response, may be because it is a Zope issue. My platform details: Zope Version (Zope 2.7.5-final, python 2.3.4, freebsd5) Python Version 2.3.4 (#2, Oct 21 2004, 17:49:27) [GCC 3.3.3 [FreeBSD] 20031106] Plone version: 2.0.5 Archetype version: 1.2.5-rc5 Any help is greatly appreciated.
