repeat doesn't seem to count transfer windows correctly. (5 posts)

  The following snippet:

  log "count of transfer windows=" & (count of transfer windows) --> 2
  repeat with w in transfer windows
  log "id of w=" & id of w
  log "w is ourTwindow? = " & ¬
  ((id of w) is (id of ourTwindow))
  end repeat

  Produces this log:
  count of transfer windows=2
  id of w=319466064
  w is ourTwindow? = false
  id of w=18810720
  w is ourTwindow? = true

  And then gets this error:
  Can't make id of item 3 of every «class cFWA» of
  application "Fetch" into type Unicode text."

  Item 3? There are only two transfer windows (count of transfer windows=2).
  Why is Fetch trying to access a third transfer window?
  Could this be a bug?

  There is a bug, but I think it's in AppleScript. You can see a similar problem with this script, which tries to walk through Finder windows and finds an infinite number:

  tell application "Finder"
  display dialog "There are " & (count every window) & " Finder windows"
  set counter to 0
  repeat with w in windows
  set counter to counter + 1
  display dialog "Window #" & counter
  end repeat
  counter
  end tell

  To work around this problem, I would replace the line:

  repeat with w in transfer windows

  with these two lines:

  set tws to transfer windows
  repeat with w in tws

  That should work.

  Thanks for reporting this -- I hadn't seen it before.

  Thanks, Jim--

  That worked just fine!

  Unless you've already done so, I will check to be sure that Apple knows about this.

  Thanks again for the help.

  Hi, Jim--

  Another way to get it to work, which may provide a clue as to why mine doesn't:

  repeat with w in (get Finder windows)

  Thanks to Brian Christmas for this one.

  Hi Gil,

  Thanks for sharing that. AppleScript's behavior is sometimes very mysterious, to me anyway.
