Well, what does your view code do in the case where form.is_valid() returns False? Based on the error it would seem it returns None (_checklogin is named simply because you've wrapped your function in it -- it's returning whatever your view function returned). Your view still needs to return an HttpResponse object even when the form validation fails.

Re: KeyError, Submit Empty Field and Form Validation
I have @login_required decorator for the view function that handles this form and I am already logged in. I commented out the "def clean" from the form and when I submit the form field reason without a value, I get this error: Exception Type: ValueError Exception Value:The view django.contrib.auth.decorators._checklogin didn't return an HttpResponse object.

The default field validation for a CharField will raise a validation error
if the field is required (which yours is, since you have not overridden the
default required=True) but empty. When that happens, the field is removed
from cleaned_data. So, by the time your form's clean() is run (after the
fields have been individually cleaned), 'reason' has already been flagged as
an error and is no longer in cleaned_data. In short -- you don't need to be
checking for this, as it's already being done by default.
