Occurence inline forms don't show up in Event Admin on django 1.3.1

[aleray]

Hi,

I have managed to install and run ixc/eventools@api-tidy. Unfortunately it seems like Occurence inline forms don't show up in the admin. The same codes works perfectly in django 1.4.

Here is my admin.py:

from django.contrib import admin
from eventtools.admin import EventAdmin, OccurrenceAdmin
from .models import ExampleEvent, ExampleOccurrence

admin.site.register(ExampleEvent, EventAdmin(ExampleEvent), show_exclusions=True)
admin.site.register(ExampleOccurrence, OccurrenceAdmin(ExampleOccurrence))

Thanks.
