Editing PDF metadata using a script works, but not with Applet

Scripting Forums AppleScript | Mac OS X

Hi all,

I have a simple script that help me in editing metadata, such as:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions
use framework "Foundation"

on run
	set therecord to {Title:"LDC tile44", Author:"LDC auth44", Subject:"LDC subj44"}
	set posixPath to "/Users/ldicroce/Desktop/10_1016@j_devcel_2021_12_007.pdf"
	my setDocumentAttributes:therecord forPDFAt:posixPath	
end run

on setDocumentAttributes:attributeRecord forPDFAt:posixPath
	set thePath to current application's NSString's stringWithString:posixPath
	set thePath to thePath's stringByExpandingTildeInPath()
	display dialog "OK1a"
	set theUrl to current application's NSURL's fileURLWithPath:thePath
	display dialog "OK1b"
	set thePDFDoc to current application's PDFDocument's alloc()'s initWithURL:theUrl
	display dialog "OK1c"
	set theDict to current application's NSDictionary's dictionaryWithDictionary:attributeRecord
	thePDFDoc's setDocumentAttributes:theDict
	return thePDFDoc's writeToFile:thePath
end setDocumentAttributes:forPDFAt:

And , it works perfectly.
But if I export the script as Applet, then it stops always at this line:

set thePDFDoc to current application's PDFDocument's alloc()'s initWithURL:theUrl

The applet has full access to the disk and folders …
Any help to overcome this?
Thanks.

It seems that the applet (but not the simple Apple script [.scpt]) triggers the following error:
PDFDocument doesn’t understand the “alloc” message.
-1708

any help ?

Your script doesn’t include the Quartz framework. After including that, the script saved as an app worked for me.

Beautiful !!! Thanks a million !!!
I was misguided (and I still don’t understand) since the script was working fine, but the applet failed …

Just in few words, when do I need to add use framework “Quartz” ?
Thanks again !

I have trouble remembering what requires a particular framework, so when in doubt I check the documentation. I believe I only use the Quartz framework for PDF stuff, but the documentation describes this framework as:
