Launchd error on simple script

Question

Hi guys !
I am having some difficulty with running a launchd, which runs an applescript. Hope you can help me.
I had a macmini server running these exact scripts before, but it died. So I copied everything to the same location on a new macmini and more or less expected it to work, but apparently, it doesn't.
FileMaker server creates timestamped backups and I wish to rename the folder as our other backup software then sees it as a unique folder, which we don't want.
The launchd is a user daemon. Should It be a system daemon ?
The Console gives me :
26-04-11 00:00:32          com.admin.renameFMBackup.folder[35196]          /Library/FileMaker Server/Data/Scripts/renameFolder.scpt:
26-04-11 00:00:32          com.admin.renameFMBackup.folder[35196]          execution error: An error of type -10810 has occurred. (-10810)
26-04-11 00:00:32          com.apple.launchd[1]          (com.admin.renameFMBackup.folder[35196]) Exited with exit code: 1
I can't find any reference to -10810 anywhere on the web, so I am hoping some like you has this one figured out.
Maybe I should be doing this another way ?
Very much thanks !
Joost.
So first the launchd script :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>Label</key>
          <string>com.admin.renameFMBackup.folder</string>
          <key>ProgramArguments</key>
          <array>
                    <string>osascript</string>
                    <string>/Library/FileMaker Server/Data/Scripts/renameFolder.scpt</string>
          </array>
          <key>StartCalendarInterval</key>
          <dict>
                    <key>Hour</key>
                    <integer>0</integer>
                    <key>Minute</key>
                    <integer>0</integer>
          </dict>
</dict>
</plist>
The applescript is very plain...
tell application "Finder"
          set theFolder to "Macintosh HD2:Netwerk:" as alias
          set theName to "BackupAVG"
  open theFolder
          set theSubFolder to every folder of theFolder
          set name of first item of theSubFolder to theName
end tell

FileMaker Server backups the files to a folder. However, they are timestamped. Our backup program thus sees it as a new folder and so the backup grows.... I rename the folder to fool the backup.
OK, that's the part I didn't get. It sounded like you were expecting the AppleScript to do the backup, which clearly it does not do.
The single quote changed the text-color to red in Lingon.... I'll have to wait and sees how it goes.
I don't think that matters. I'd still err on quoting the entire path rather than a single element within it.
One more question... If I want to log out but still run the script. Do I make it a system daemon ?
I think you're doomed to failure here. If you want to run it while logged out, how is your script supposed to talk to the Finder to find/rename the backup folder - the Finder isn't running, and can't be launched becuase there's no logged-in user.
In fairness,that's not entirely true since root-based scripts can attach to the WindowServer, but it's still the wrong approach to your problem. I'd recommend nixing AppleScript for this and just using a shell script (which has no UI dependencies).
For example, the following shell script will find the most recent file in a directory and rename it (just ask if you don't understand the components);
#! /bin/bash
cd /Volumes/Macintosh\ HD2/Netwerk
ls -t | head -1 | xargs -I % mv % BackupAVG
Just change the path in the third line to point to the directory your backups are saved to.
