fix bug in which hiddenNodes was reference on gview.get('hidden_node'). So any changes on hiddenNodes was modifying the original array too, preventing us to come back to the original state of the view.
<?php
require_once(realpath(dirname(__FILE__) . "/../resources/config.php"));
require_once(LIBRARY_PATH . "/templateFunctions.php");
$variables = ['config' => $config, 'renkanId' => $_GET['renkanId']];
$css = [
'static/lib/renkan/css/renkan.css'
];
renderLayoutWithContentFile("renkan_read.php", $variables, $css);
