Using CustomUploadHandler, request.FILES is empty

[Stu.Axon]

I'm using a CustomUploadHandler for one of my views, but the form is
always invalid - also request.FILES is also blank ?
I'm a bit new to django, so not entirely sure whats going on

## form
class UploadMidletPairForm(ModelForm):

    class Meta:
        model = MidletPair

### uploadhandler
class CustomUploadHandler(FileUploadHandler):
    def __init__(self, request = None, upload_to = tempfile.gettempdir
()):
        self.upload_to = upload_to
        FileUploadHandler.__init__(self, request)


    def new_file(self, field_name, file_name, content_type,
content_length, charset=None):
        #if not is_valid_upload(file_name):         # here you can use
a function to filter uploaded files.
        #    raise    UploadFileException , "forbidden file type"
        if not os.path.exists(self.upload_to):
            os.makedirs(self.upload_to)
        elif not os.path.isdir(self.upload_to):
            raise IOError("%s exists and is not a directory." %
self.upload_to)

        outPath = os.path.join(self.upload_to, file_name)
        self.destination = open(outPath, 'wb+')
        FileUploadHandler.new_file(self, field_name, file_name,
content_type, content_length, charset)

    def receive_data_chunk(self, raw_data, start):
        self.destination.write(raw_data)

    def file_complete(self, file_size):
        self.destination.close()


### view

@login_required
def validate_build(request):
    '''
    Jad/Jar upload form
    '''

    # Save the file to disk
    print >> sys.stderr, request.user
    request.upload_handlers = [CustomUploadHandler(upload_to =
os.path.join(settings.MEDIA_ROOT, 'superglu', 'userdata', str
(request.user), 'validate'))]
    UPLOAD_FORM_TITLE = 'Validate Build'
    if request.method == 'POST':
        form = UploadMidletPairForm(request.POST, request.FILES)

        if form.is_valid():
            print >> sys.stderr, 'is valid'
            jad = request.FILES['jad_file']
            jar = request.FILES['jad_file']

        else:
            print >> sys.stderr, 'is not valid'
            print >> sys.stderr, form.errors
    else:
        form = UploadMidletPairForm()
    return render_to_response('validate/build/index.html',
context_instance = RequestContext(request,\
        {
        'form': form,
        'title': UPLOAD_FORM_TITLE,
        }))



### template
{% extends "base.html" %}
{% load i18n %}

{% block breadcrumbs %}
<div class="breadcrumbs">
    <a href="../">{% trans 'Home' %}</a> &rsaquo;
    <a href="/validate/">Validate builds</a> &rsaquo;
    <a href="/validate/">Build</a> &rsaquo;
</div>
{% endblock %}

{% block content %}
<div id="content-main">
{% if perms.validate %}
<h2>Upload Jad/Jar pair</h2>
<form action="." method="post" enctype="multipart/form-data">
<fieldset>
{% if form.image.errors %}
    <ul class="errorlist">
    {% for error in form.image.errors %}
        <li>{{ error|safe }}</li>
    {% endfor %}
    </ul>
{% endif %}
{{ form }}
</fieldset>
<input type="submit" value="Validate" />
</form>
{% else %}
Sorry, your user is not enabled for validation
{% endif %}
</div>

{% endblock %}
