$albumRequestVar don't work for child albums when cached

[suetti]

galalbum.class.php line 298

The cachekey don't consider the $parent, so the cachekey always contains parent = 0;

One suggestion for a solution:

    /* implement tree-style albums*/
    if ($modx->getOption('checkForRequestAlbumVar',$scriptProperties,false)) {
        $albumRequestVar = $modx->getOption('albumRequestVar',$scriptProperties,'galAlbum');
        if (!empty($_REQUEST[$albumRequestVar])){
            $parent = $_REQUEST[$albumRequestVar];
            $scriptProperties['parent'] = $parent;
        };                            
    }

    $cacheKey = 'gallery/album/list/'.md5(serialize($scriptProperties));
