ITunes - update info problem

Question

Hi,
I've got a problem with a workflow that should update the info of songs added to iTunes. It's part of a larger one, but I've stripped it down, yet it still silently fails (there's no error message, and it says the workflow was successful).
The script is this:
1. Get selected Finder items
2. Add files to Library
3. Update info of iTunes songs
Does anyone know why the last step fails (the songs aren't updated)?
Thanks in advance.
(If it helps, the workflow can be found at: http://bonaldi.thehold.net/apple/iTunes.zip though you'll need to have a MP3/AAC file selected in the Finder for it to work at all

That's a cool bug! I played with your workflow and found that while it fails on single items, it succeeds when multiple items are selected in the Finder. I figured this must just be a goof on the part of the action's author, who assumed that incoming data would be provided as a list class. You can patch this up manually by sticking the Run AppleScript action between your Add Files to Playlist and Set Info of iTunes Songs actions. Replace its default code with the following…
click here to open this script in your editor<pre style="font-family: 'Monaco', 'Courier New', Courier, monospace; overflow:auto; color: #222; background: #DDD; padding: 0.2em; font-size: 10px; width:400px">on run {input, parameters}
if class of input is list then
return input
else
return {input}
end if
end run</pre>…which will make sure that the data is passed in the list class. This sort of coercion is supposed to be handled behind-the-scenes by conversion actions (aka .cactions), someone simply must have forgotten to tape up this connection.
