Many-to-Many with Intermediate Table Bug in Admin in Django 0.95?

[Paul Childs]

Could someone please tell me if this is an unfixed bug in Django 0.95.
If it is I will submit a ticket.

I created a many-to-many relationship using an intermediate table
similar to
http://www.djangoproject.com/documentation/models/m2m_intermediary/
(see model below.)

I am able to successfully exercise the models with no problem in the
shell.

When I go to the Admin and I create an Action or a Reference document
and click on save the Admin throws an exception. But the Action or
Reference is still added to the database.

I searched existing tickets and found similar issues but I'm not sure
if they address the same circumstances.

Thanks,
/Paul


Models:

-----------------------------------------
from django.db import models

class Action(models.Model):

    name = models.CharField(maxlength=20)

    class Admin:
        pass

class ReferenceDocument(models.Model):

    document_number = models.CharField("Document",maxlength=50,
core=True)
    document_type = models.CharField(maxlength=5)

    class Admin:
        pass

    def __str__(self):
        return self.document_number

class ActionReference(models.Model):

    action = models.ForeignKey(Action)
    reference_document = models.ForeignKey(ReferenceDocument)
    note = models.CharField(maxlength=50)

    class Admin:
        pass
