Matt;

I really take offense at your tone.  I was not lying.
I merely clipped out my personal details in order not to provide them to the world. The 'theScript' IS a string - constructed in ObjC differently than you show but a string nonetheless.

Turns out the error was that an SDEF file had been renamed.

Folks;

I'm trying to get a string value back from a simple AppleScript in
Cocoa:

NSDictionary *errorDict= nil;
NSAppleScript *appleScriptObject = [[NSAppleScript alloc]
initWithSource:theScript];
NSAppleEventDescriptor *eventDescriptor = [appleScriptObject
executeAndReturnError: &errorDict];
[appleScriptObject release];
if (([eventDescriptor descriptorType]) && (errorDict==nil)) {
return [self stringFromAppleEventDescriptor:eventDescriptor];  //my
own method that checks descriptorType and returns stringValue
} else {
NSLog(@"%@",[errorDict objectForKey:@"NSAppleScriptErrorMessage"]);
return nil;
}

The 'theScript' is a valid script that executes flawlessly in 'Script
Editor':
tell application "Finder"
try
comment of file ("/Users/steve/...." as POSIX file)
on error
return "Error"
end try
end tell

The problem is that the above errors out @ [appleScriptObject
executeAndReturnError: &errorDict];
The stack is shown below.

That's hard to answer because you're so obviously lying. You are not
reporting what you're really doing. What is theScript really? A string? Show us the string. And clearly you are not really saying /Users/ steve/...., so
show us what you *are* saying.

Let me show you how to answer. Here is a *complete* valid chunk of *real*
Objective-C code:

   NSString* theScript = @"tell application \"Finder\"\n"
   @"try\n"
   @"set pp to \"/Users/mattneub/Desktop/BrahmsHandel2.mus\"\n"
   @"comment of file (pp as POSIX file)\n"
   @"on error\n"
   @"return \"Error\"\n"
   @"end try\n"
   @"end tell\n";
   NSDictionary *errorDict= nil;
   NSAppleScript *appleScriptObject = [[NSAppleScript alloc]
initWithSource:theScript];
   NSAppleEventDescriptor *eventDescriptor = [appleScriptObject
executeAndReturnError: &errorDict];
   [appleScriptObject release];
   if (([eventDescriptor descriptorType]) && (errorDict==nil)) {
       NSLog(@"%@", [eventDescriptor stringValue]);
   } else {
NSLog(@"%@",[errorDict objectForKey:@"NSAppleScriptErrorMessage"]);
   }

I actually ran that code and it actually works (the finder comment from the
specified file appears in the log). Okay, now it's your turn. :) m.
