Re: [fw-mvc] Zend_Form_Element_File value when not uploading

There is only one file adapter because you have only one $_FILES input
array.
Having multiple file adapters would not work. This is mentioned, because the
first would try to receive the files and the second would then throw an
exception because there are no more files to receive.

What you have in those two variables is the same adapter.

And actually you are calling isUploaded on the adapter (which hold all
uploaded files) and not the form element (where this new method does not
exist for now).
