Rather than rustle through the code to work this out, I'll just explain
how I would go about debugging this: AttributeError suggests you are
calling .append() on something that isn't a list. So I would first look
at what the type of form['fieldname'] is in the cases where you are
getting the error. I suspect you will find it is something like None.
Then I would look at how errors are put into the error list in the
standard clean_data() functions. What do they (or their callers) do that
is different from what you are doing? Look for everywhere that
form['fieldname'] is created or modified in newforms/forms.py,
particularly in the Form class.
That should give you a better idea about what the root cause of the
problem is and also show you how Django itself deals with those fields
so that you can emulate it more closely.
