Automator bug when save as finder plugin

Question

I've got a simple workflow that I've saved it as Finder plugin.
1)Get Selected Items
2)Open Finder Items (choose an application to open)
I can run the workflow within automator. But when I save it as a Finder plugin, running it via the finder contextual menu doesn't work. I tried debugging and found these errors in /var/log/system.log whenever I run the worklow as a plugin.
Nov 17 19:07:35 MyMac Automator Runner\[2414\]: Error while processing arguments
Nov 17 19:07:37 MyMac Automator Runner\[2414\]: The action “Initiate Remote Broadcast” could not be loaded because the application “QuickTime Broadcaster” was not found.

Answer 1

Finder is passing a list to Automator's workflows as the parameter 'input'. I found there were two items in the list for a given item selected in Finder:
The first was the POSIX-style path to the selected item: /Users/jd/filename.
The second was the older-style, non-UNIX, path: Macintosh HD:Users:jd:filename.
When I ran my workflow within Automator I found only the old-style path was being passed to my script.
Debugging techniques:
1) Determining the class of the 'input'; in this case a 'list' NOT a 'string' as I'd assumed.
2) Using a try-on error block to retrieve error info.
Here's my code. In my workflow this applescript is preceded by a Finder command to get the selected items.
on run {input, parameters}
set commitInfo to "No repository information"
set finderItemList to input
set inputAsString to ((item 1 of finderItemList) as string)
set pathAsString to POSIX path of inputAsString
try
set commitInfo to do shell script "cd " & pathAsString & "; git log"
display dialog commitInfo
on error errTxt number errNum
set errMsg to pathAsString & " " & errTxt
display dialog errTxt & return & errNum
return input
end try
return commitInfo
end run
