Hello Plone Community,

after uninstalling (Quickinstaller) and removing (from buildout)
LinguaPlone any attempt to access the plone site or the ZMI (even ZMI
root) failes with the following stack trace:

Maybe it's a bug in LinguaPlone which claims to uninstall cleanly.
Any hints are appreciated.

Plone 4.0b4, LinguaPlone 3.1a5

Thanks in advance

Michael

I think you've to remove it manually, this is a little guide I've
created to do it (just change the interface name):

In a product or egg with a browser dir, create this:

=================== browser_remove.py =================

from Products.Five import BrowserView
from zope.component import getMultiAdapter
from zope.interface import alsoProvides, noLongerProvides
from zope.component.interface import interfaceToName
from cab.contentextender.interfaces import IDocumentExtended

def remove_marker(object):
changed = False
if IDocumentExtended.providedBy(object):
noLongerProvides(object, IDocumentExtended)
changed = True
if changed:
object.reindexObject(idxs=['object_provides'])

class RemoveCabExtView(BrowserView):

def __call__(self):

tools = getMultiAdapter((self.context, self.request),
name='plone_tools')
catalog = tools.catalog()

brains = catalog(object_provides=interfaceToName(self.context,
IDocumentExtended))

for brain in brains:
obj = brain.getObject()
remove_marker(obj)

return ('Removed IDocumentExtended interfaces from %i objects
for cleanup' % len(brains))

===========================

and add to configure.zcml (always in the browser dir) this:

<browser:page
for="Products.CMFPlone.interfaces.siteroot.IPloneSiteRoot"
name="remove-interface"
class=".browser_remove.RemoveCabExtView"
permission="cmf.ManagePortal"
>

=========================

Now reload and go tohttp://miositoplone/@@remove-interface

The code is inspired by:

http://plone.org/products/collective-flowplayer/issues/5 , adding what is missing.
