Ok, I've done so.

I've created a INameChooser implementation:


from zope.app.container.interfaces import INameChooser
    
class NameChooser:
    implements(INameChooser)
    
    def __init__(self, context):
        self.context = context
    
    def chooseName(self, name, object):
        print object
        return object.title

gives the traceback:

2005-05-23T22:01:13 ERROR SiteError 
http://localhost:8080/cs/home/zope.manager/t
estfolder/+/AddCSLink.html%3D
Traceback (most recent call last):

line 22, in chooseName
    return object.title
AttributeError: 'Link' object has no attribute 'title'

but the Link object has a attribute title.

    title = TextLine(
        title = u"Title",
        description = u"Short title",
        required = True
        )

What is wrong there?

Thanks,

Florian
