title: ManagementForm data missing error while formset validation
body: <p>formset creation in views.py:</p>
  
  <pre><code>ffact = formset_factory(Form,extra=somenum]))
  fset = ffact(prefix='pfix')
  </code></pre>
  
  <p>validation in views.py:  </p>
  
  <pre><code>ffact = formset_factory(Form,extra=3))
  fset = ffact(request.POST) 
  if fset_is.valid():
      blah blah
  </code></pre>
  
  <p>this is resulting in Exception Type: ValidationError at /app/index/
  Exception Value: [u'ManagementForm data is missing or has been tampered with']  <a href="http://docs.djangoproject.com/en/1.1/topics/forms/formsets/#understanding-the-managementform" rel="nofollow noreferrer">django-docs</a>
  did mention about this. I'm not sure how to provide management data. I tried something like <a href="https://stackoverflow.com/questions/2536285/django-formset-management-form-validation-error">this</a> ,</p>
  
  <pre><code>try:
    fset = ffact(request.POST)
  except ValidationError:
    fset = None
  if fset and fset.is_valid():
    blah blah
  </code></pre>
  
  <p>But still i get the same error.Any ideas? Thanks.</p>
