Comment (by CarstenF):
Looking at Django 1.7.5's `BaseForm.changed_data()`, debugging indicates
that line
{{{
#!python
elif field._has_changed(initial_value, data_value):
}}}
for field `monat` of my above example turns into
{{{
#!python
elif field._has_changed(u"", 1):
}}}
Thus, afaics, it rather seems that `initial_value` is wrongly determined
earlier, when call `hidden_widget.value_from_datadict(self.data,
self.files, initial_prefixed_name)` returns `None` rather than 1.
`self.data` in turn has no key `initial_prefixed_name` (here "initial-
monat"), causing the `None` return value above.
What I wonder about is how and where "initial-monat" should have been
added to `self.data` in the first place...?
