Error when saving form with a manytomany field

[elpaso]

Hello,

I tested both 1.1.1 and SVN trunk and got the same error when saving a
form, any help would be highly appreciated, details follow.

The tables are in place, basically I have a m2m relation between Track
and TrackCategory, if that matters, categories are implemented with
django-mptt.


class TrackCategory(Category):
......

class Track(ResourceBase):
category = models.ManyToManyField(TrackCategory)
......



Exception Value:
__init__() takes exactly 2 arguments (1 given)
Exception Location: /usr/lib/python2.5/site-packages/django/db/models/
fields/related.py in __init__, line 415

The trace shows:

415 super(ManyRelatedManager, self).__init__()

Vars:
Variable Value

<class 'django.db.models.fields.related.ManyRelatedManager'>
core_filters

Ok, It turned out to be a wrong (custom) default manager, I thought
the last declared manager was the default one, while as it's clearly
written in the docs, it is the first one which becomes the default.
