The context processor is not invoked, because you're not using a 
RequestContext. So the messages variable is not added to your context. The 
last line should be:

return render_to_response('mymodel_create.html', {'form' : form}, 
context_instance=RequestContext)

See the documentation:
 
http://docs.djangoproject.com/en/1.2/ref/templates/api/#subclassing-context-requestcontext

to link to directly)

Re: Messages framework is not showing messages in my templates

[Xavier Ordoquy]

Hi,

It's been some time I haven't used the messages framework but don't you see 
your messages with some lags ?
Like try to submit twice your form and see if you don't get the messages after 
the second post (and don't go in the admin between those requests).
When forms are valid, I usually redirects to the same page (or another one 
depending on edit/create mode) and the messages show up.

Regards,
Xavier.
