[Zope3-Users] Can't rename objects

[Florian Lindner]

Hello,
I have a container object to which I can add and remove object but can not 
rename them. I suspet my I namechooser to be faulty:

from zope.app.container.interfaces import INameChooser
from zope.app.container.contained import NameChooser

class XGMNameChooser(NameChooser):
    implements(INameChooser)
    
    def chooseName(self, name, object):
        if IAbbreviation.providedBy(object):
            # my name choosing code
            return n
        else:
            return super(XGMNameChooser, self).chooseName(name, object)


registered like that:

    <adapter
        for=".interfaces.IXGM"
        provides="zope.app.container.interfaces.INameChooser"
        factory=".xgm.XGMNameChooser"
    />


furthermore the objects interface implements:

IContainer, IContained, IPossibleSite, IAttributeAnnotatable, 
IContainerNamesContainer.

the class itself:

BTreeContainer, SiteManagerContainer

What's wrong?

Thanks,

Florian
