Moving a playlist to a folder.

gistfile1.m

if (_appFolder) {
    NSArray * containerPlaylists = container.playlists;
    for (SPPlaylist * containerPlaylist in containerPlaylists) {
        // move all playlists tagged with SpotON Radio:
        if ([containerPlaylist.name rangeOfString: kPlaylistNameMatch].location != NSNotFound) {

            NSInteger playlistIndex = [[container playlists] indexOfObject: containerPlaylist];

            DLog(@"-> MOVE playlist %@ at index %i", containerPlaylist.name, playlistIndex);

            // retain playlist while working with it
            [containerPlaylist retain];

            // move playlist
            NSError * error = nil;

            BOOL success = [container movePlaylistOrFolderAtIndex:playlistIndex ofParent: nil toIndex: 0 ofNewParent: _appFolder error: &error];
            if (success) {
                // rename playlist
                DLog(@"Success! Playlist moved to folder (error: %@).", error);

                // check the folder structure
                for (SPPlaylist * folderPlaylist in [_appFolder playlists]) {
                    DLog(@"Playlist %@ in folder...", folderPlaylist.name);
                }
            } else {
                DLog(@"Failed to move playlist %@ with error: %@", containerPlaylist.name, error);
            }

            // release playlist
            [containerPlaylist release];
        }
    }
}

_appFolder is a previously stored instance var, representing the folder to which I want to move the playlist.

When I'm running this code, I'm getting the "success" message, the folder and playlist is created in Spotify (with an added track), but the playlist hasn't been moved to the folder.

The log output on #23-#25 doesn't print out anything and the structure doesn't look right in Spotify.
