Import Folder Action Problem (and fix)

I often print articles that I come across on the 'tubes to PDF in a specific folder, which has the “Import” folder action attached. I noticed that some of these I had to go and import by hand, which irritated me.

Of course, the (rather simple) problem was that OS X created the PDF file (which triggered the import script) and so, for long documents, OS X would still be writing to the file while DEVONthink was trying to import it, and so it’d fail.

The solution was just to toss a delay in:

-- Action Import.applescript
-- DevonThink Pro

on adding folder items to this_folder after receiving added_items
		tell application "DEVONthink Pro" to launch
		repeat with theItem in every item of added_items
				set thePath to theItem as text
				if thePath does not end with ".download:" then
					delay 10
					tell application "DEVONthink Pro" to import thePath
				end if
			end try
		end repeat
	end try
end adding folder items to

The 10-second delay might seem long, but I just checked and the folder actions queue up very nicely (in Leopard at least), so it shouldn’t cause any untoward behavior.

DEVONthink Pro tests the file before actually importing it, I presume from the graceful error – would it be possible to build in a little timeout period of ten seconds so that if a file is being written when an import is requested, it’ll wait a bit to see if the action completes within a few seconds?
