Validating multidimensional arrays

I have two fields, named title[1] and title[2].

Indexes are used to mention the language id.

---

When I use this;

Code:

$this->form_validation->set_rules("title[]", "Menu title", "required");

It only validates the first index but not second or others using CodeIgniter 2.2.1. I want to know is there any fix so CI its self check for all the indexes and apply the same rule. Just like set_value["title[]"] reloads the value for each field automatically.
