[CPS-devel] More about CalCMF AttributeError

[Morten W. Petersen]

Hi,

still working on that AttributeError: getPhysicalPath bug I'm
encountering in CalCMF.

The problem seems to be that due to some magical Five traversal, some
places a calcmf calendar instance's parent can be an instance of
Products.Five.metaclass.SimpleViewClass.

The bug isn't visible on home calendars, because self._attendee_name !=
'' doesn't evaluate to true.

On calendars created elsewhere the bug is visible, and the statement
self._attendee_name = '/'.join(self.getPhysicalPath()) fails because
self in this case is a CmfCalendar instance with the acquisitional
parent Products.Five.metaclass.SimpleViewClass..

You can see what I'm talking about by adding

  print 'calendar is', calendar, calendar.aq_parent

at line line 172 of CalZope/browser/calview.py - it says

calendar is <CmfCalendar at calendar>
<Products.Five.metaclass.SimpleViewClass from
/home/morphex/CalCMF/CalZope/browser/week.pt object at 0xb4ec7a2c>

on a working "home folder" calendar..  I see two ways of fixing this;
either changing the if self._attendee_name == '': code in
CalCMF/calendar.py or by fixing the traversal.  What do you think?
