ClearableFileInput doesn't render a currently value when invalid

[Hiroki Kiyohara]

Hi, all.

Problem
=======
In updating objects(UpdateView and so on), django.forms.widgets.ClearableFileInput doesn't render a currently value when the POSTed data was invalid(for example, uploading PDF file to ImageField using ClearableFileInput).
The HTML rendered when invalid error is only includes input tag. It's natural to render more components ("Currentry: /path/to/spam", clear checkbox and so on).

For more detail
----------------------
And the input field rendered when invalid error allows empty, even if the field is required. And it allows empty submit. In this case, the currently value will retain. This behavior is gross. seriously.

Why this happens
===============
render method on ClearableFileInput isn't render currently value and checkbox when value arg is empty.
When validation error is raise, the arg will be empty.

Django's version
==============
I found this behavior in Django==1.4.1

conclusion
=========
If you can't understand my poor English or this problem is my misunderstanding, sorry, please tell me so.
