[Zope3-Users] Problem with containment and @@absolut_url

[Mats Nordgren]

Achim,

context/articles would return the id's

>>> d = {'one':1, 'two':2}
>>> for item in d:
... 	item
... 	
'one'
'two'

The id is a string which has a title method (capitalize each worlds first
letter); this is why your article/title is working.

>>> for item in d:
... 	item.title()
... 	
'One'
'Two'

You probably should use context/articles/values for the loop.

Cheers,

Mats
