Yep, this was intentional behavior. Luckily, it's easy enough to provide
your own functionality by extending the class. The method is quite short:
/**
* Brings the page number in range of the paginator.
*
* @param integer $pageNumber
* @return integer
*/
public function normalizePageNumber($pageNumber)
{
if ($pageNumber < 1) {
$pageNumber = 1;
}
$pageCount = $this->count();
if ($pageCount > 0 and $pageNumber > $pageCount) {
$pageNumber = $pageCount;
}
return $pageNumber;
}
