attachment_fu + SWFupload via activeupload

hi there,

I am using the activeupload plugin with attachment_fu and keep getting “406 Not Acceptable” errors when I try and upload a file, is there anything magic I need to do to get these to work?

I also get AttachmentsController: missing default helper path attachments_helper but rails freaks out when I put “include ActiveUploadHelper” in application_helper.rb

cheers for any tips
