Getting an error when trying to store database in cache directory

Question

Hello,
"SQLError: 'Error #3125: Unable to open the database file.', details:'Connection closed.', operation:'open', detailID:'1001'"
this is my code :
sqlConn = new SQLConnection();
var str:String=File.applicationDirectory.nativePath;
var cacheDir= new File(str +"/\.\./Library/Caches");
var dbFile:File=cacheDir.resolvePath("DB.db");
sqlConn.open(dbFile);
sqlStat = new SQLStatement();
sqlStat.sqlConnection=sqlConn;
It works if I use var dbFile:File=File.applicationStorageDirectory.resolvePath("DB.db");

With AIR 3.6 latest prerelease, A new static property, File.cacheDirectory has been added, which points to the <APPLICATION_HOME>/Library/Caches directory on iOS devices, and files in this directory are not backed up. So, the above workaround is not required.
Another property, preventBackup is introduced in the File API, which when set prevents a file or a folder from getting backed up on the iCloud. This property works on iOS 5.1 devices and later.
