[Zope-CMF] [dev] DateIndex and __CEILING_DATE

[yuppie]

@ Gitte and Tres: I cc'd you because I refer to old mails of you.


Hi!


Today I stumbled over this mail and thread:
<http://mail.zope.org/pipermail/zope-cmf/2003-November/019773.html>

Why is there a need to run a conversion script to replace __CEILING_DATE 
by 'None'?

AFAICS 'None' is already stored in the content objects and all that 
needs to be changed is this line in DefaultDublinCoreImpl.expires():

     return date is None and self.__CEILING_DATE or date

(At least basically. Full backwards compatibility would be a bit more 
complex.)


What am I missing?

Cheers,
