I'm trying to change the URL path for grader/lib.php overriding parent class constructor.
I have extend grade_report_grader and override $this->pbaurl but nothing happens.
class my_grader_plugin extends grade_report_grader {
public function __construct($courseid, $gpr, $context, $page=null, $sortitemid=null){
parent::__construct($courseid, $gpr, $context, $page);
$this->pbaurl = new moodle_url ('/grade/report/myreport/index.php', array('id'=>$this->courseid));
}
}
