Scripting question: how to suppress Aperture dialog when exporting?

Question

Hi Forum,
I started to write an AppleScript for Aperture to perform a backup. The standard backup procedures of Aperture are not quite right for me so I decided to write my own using AppleScript.
One question which arised was how I can supppress the dialog box which Aperture opens when an export could not be done because of a missing master. I want to suppress the dialog box and instead get an error returned from Aperture into AppleScript. is that possible?

Hello Koen,
have you solved your problem by now? For me the following does work:
I does not seem to be possible to set Aperture to suppress the warning, so catching the error in a "try" clause will not help. The best option is to check, if the master image is online, before trying to export and skipping the offline images, like in this example,  see: http:/dreschler-fischer.de/scripts/ExportMastersWithoutWarning.scpt.zip
on run {}
  -- export masters, but check it they are online before trying to export
  -- skip if not online
          set exportFolder to (choose folder with prompt "Choose an export folder")
          tell application "Aperture"
                    set imageSel to (get selection)
                    if imageSel is {} then
                              error "Please select an image."
                    else
                              repeat with i from 1 to count of imageSel
                                        try
                                                  set onlne to get online of (item i of imageSel)
                                                  if onlne then export {item i of imageSel} naming folders with folder naming policy ¬
                                                            "Project Name" to exportFolder
                                        end try
                              end repeat
                              return imageSel
                    end if
          end tell
end run
