jsonify.get_item() fails due to AttributeError exception with isDiscussionAllowedFor

[mcv21]

Hi,

I'm using Plone 4.2.5. When I attempt to use get_item() against anything in my site, I see the following:

from collective.jsonify import get_item
site=app['SITENAME']
print get_item(site['foo'])

results in the following:

ERROR: exception wrapping object: isDiscussionAllowedFor
['  File "/home/mcv21/falconsvn/light/src/collective.jsonify/collective/jsonify/methods.py", line 29, in get_item\n    context_dict = Wrapper(self)\n',

After some discussion on plone-users, Daniel Jowett suggested I try his fork of this code, https://github.com/djowett/collective.jsonify/ which has a few differences in how it handles archetypes fields. That works fine, though I'm not sure exactly what the necessary change is, and I'm guessing you can run git diff as well as I can ;-)

Thanks,

Matthew

Hi @mcv21,
are you in a position to try rerunning this against master to check if it's fixed there? @thet has kindly merged in my code, so it should run OK.

Cheers,
Daniel

Might be fixed...
