What happens if you run the following?

Applescript:

set deskPath to POSIX path of (path to desktop)

set deskPath to current application's NSString's stringWithString:deskPath
set FILE_PATH to deskPath's stringByAppendingPathComponent:"Test file"
set nDataSource to current application's NSMutableArray's arrayWithArray:{1, 2, 3, 4, 5}
set theResult to (nDataSource's writeToFile:FILE_PATH atomically:true) as boolean
if not theResult then
   display dialog "Saving failed"
   error number -128
end if
set myDataSource to (NSArray's arrayWithContentsOfFile:FILE_PATH)'s mutableCopy()
set theList to myDataSource's componentsJoinedByString:", "
display dialog (theList as text)

The first part works properly:

Applescript:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "[url]http://www.apple.com/DTDs/PropertyList-1.0.dtd[/url]">
<plist version="1.0">
<array>
   <integer>1</integer>
   <integer>2</integer>
   <integer>3</integer>
   <integer>4</integer>
   <integer>5</integer>
</array>
</plist>

The second (reading) part did nothing: no answer, no crash.

My saved file has the form of a dict:

Applescript:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "[url]http://www.apple.com/DTDs/PropertyList-1.0.dtd[/url]">
<plist version="1.0">
<array>
   <dict>
       <key>derName</key>
       <string>Albrecht, Katrin</string>
   </dict>
   <dict>
       <key>derName</key>
       <string>Burger, Klaus</string>
   </dict>

"derName" (theName) wil be inserted into a table view by the key in the course of the run.

My apologies -- I left out current application's:

Applescript:

set myDataSource to (current application's NSArray's arrayWithContentsOfFile:FILE_PATH)'s mutableCopy()

To DJ Bazzie Wazzie:

Sorry, but my app is perhaps to old. It doesn't understand

use framework "Foundation"
use scripting additions

and without it, it works not either.


To Shane:

Now your snippet are working correctly. I'll try to adopt it into my app and give a response later.

The saving lines and the 'form' of saving are on top (but I think I haven't understand the problem).

To make a notice beforehand: my app worked up to now.
But now I can read and write the file from and to everywhere but not to (my)Library/Application Support/"myFile" .
The name of "myFile" is readable but the contents of it is not loadable.
What happened meanwhile?

Heiner

That's my script:

Applescript:

property userLocationSchuelerDaten : (path to "asup" from user domain) & "SchuelerListenDaten" as text

set myPath to POSIX path of ((userLocationSchuelerDaten as text) & ":" & (selectedContent as text))

— - selectedContent: user selected a file in a tab. view

display alert (myPath as text) —>

/Festplatte/Users/heinrichhoffmann/Library/Application Support/SchuelerListenDaten/Testliste kurz —> correct

( /Harddisk/Users/myComputer/Library/App..Sup/myFolder/myFile)

set helpDataSource to NSMutableArray's alloc()'s initWithContentsOfFile:myPath

set anzahl to helpDataSource's |count|()
display alert (anzahl) —> correct

set a to (helpDataSource's valueForKey:"derName") as list —(see the pList above)

display alert ("a") —> error -1708                
display alert (a) —> error -1700

Meanwhile I noticed that Apple has published a new Xcode version (Xcode 8) without an automatic update. My OS system is OS 10.12 now.
The maximum of project target of my Xcode version is to set for 10.11.
Does that be the reason for my troubles now?

I don’t get any more debug informations in the pane below, so not
current application's NSLog("helpDataSource = %@", helpDataSource).

Compiling the file in the project setting view I get in the debugging view pane by clicking the ‘Debug View Hierarchy’ button the following message:

warning: could not load any Objective-C class information from the dyld shared cache. This will significantly reduce the quality of type information available.
(lldb)

if the situations allows you too. Running Xcode 3.2 to develop for 10.12 here in some occasions.
