Is it possible in Rails3, to have a multipart form => true & use remote => true

I'm using the following form tag for @jobs which have job_photos included.

<% form_for @jobs, :html => { :multipart => true }, :remote => true do |f| %>

The form works fine non-remote, but if I add the remote = > true, the form submits, returns create.js but doesn't save anything to the DB or error?
