URL method of Tab's doesn't work as expected

When setting up tabs in jquery UI u can specify relative path so if I were in http://somedomain.com/V/ and i referenced a/p.php to get http://somedomain.com/V/a/p.php it works fine. If you use the url method and u did a/p.php it will go for http://somedomain.com/a/p.php instead.
