9775	admin multi-table inheritance broken since rev 9602	chr	Malcolm Tredinnick	"hi there,

this has driven me mad for some hours but think i've tracked down the culprit... i've made a lot of changes to my code, and updated the django svn... bad mistake.

anyway, here's my model(s):
{{{
class PublishableItem(models.Model):
    title = models.CharField(max_length=200)

class EventItem(PublishableItem):
    location = models.TextField(blank=True)

class Concert(EventItem):
    band = models.CharField(max_length=200)

class Meeting(EventItem):
    topic = models.CharField(max_length=200)
}}}
now, in change_list.html the admin will throw this:
{{{
Caught an exception while rendering: Concert has no field named 'publishableitem_ptr_id'
}}}
when updating to rev 9601 the error disappears, and changeset #9602 actually changed some things in this department. not sure how the next few changesets might interfere with this."		closed	contrib.admin	dev		fixed			Unreviewed	0	0	0	0	0	0
