Re: html:file usage

[Ed Jenkins <andexor@yahoo.com>]

That kind of behaviour is not what anyone would want, but I believe it is standard behaviour.  The
only way to get a value pre-populated in it is to do this:

1.  Create a hidden field.
2.  Write some JavaScript that copies the value from the file field to the hidden field just
before the form is submitted.  This needs to be executed in the onclick event handler for your
submit button or graphic, not from inside form_onsubmit.  This is because, IIRC, the form_onsubmit
event is not fired if the form is submitted programmatically (i.e. with script that calls
frm.submit()).
3.  When the form is kicked back to the user, place the filename in the hidden field and write
more JavaScript that runs in the body_onload event and copies the value back from the hidden field
to the file field.
