'PageAdmin.fieldsets[1][1]['fields']' refers to field 'tags' that is missing from the form.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Get code from svn repository
2. Run syncdb, runserver, Page already registered error
3. Comment out mptt.register() (Why do I need to do this? Is something
wrong at this step itself?) in model, then get this error

+ If I comment out admin.autodiscover() in my urls.py then things work of
course, but nothing to do in Admin then :(

What is the expected output? What do you see instead?
+ Working admin, but get this error

What version of the product are you using? On what operating system?
+ Trunk, Mac OSX, with Django 1.0.1

Please provide any additional information below.

Try to update to the last revision. This problem should be fixed.

What does latest revision mean?? I got the code from svn trunk, isn't that the 
latest?

Original comment by sumit.ch...@gmail.com on 19 Nov 2008 at 6:02

You require mptt.register() you commented out in step 3.

That's a function of django-mptt that is used by page-cms. See 
http://code.google.com/p/django-mptt/ for 
more information.

Well if I leave the register there then I am getting "The model Page has 
already been
registered" error. Not sure why thats happening.

Is this code supposed to work with Django 1.0+ ??

FYI, standalone it seems to run just fine!! I would rather have everything run 
within
my old code-base, although running 2 django apps on same db may be a 
possibility.

What in my current app is causing this, any idea? admin.autodiscover() called 
from
many points in the code ? How can I fix this by making minimal changes to the 
source,
and/or if i can contribute a patch to fix this since others seem to be facing 
similar
issues.

"What in my current app is causing this, any idea?"

It's hard to tell without knowing your code.

Original comment by batiste....@gmail.com on 20 Nov 2008 at 10:39

[GoogleCodeExporter]

Yes, page-cms works on Django 1.0+

As Batiste said, it's hard to tell without knowing the structure of your Django 
project. I added a simple exception 
handling in r221 to handle that situation. It's most likely caused by different 
import paths, e.g. having pages in a 
project namespace 'myproject.pages' while pages uses the plain 'pages' 
namespace.

@sumit.chachra: Does it work for you now?

Haven't had time to re-try. Will do and post here!

Without anymore news from sumit.chachra, I decide to close this bug for now.
