Possible form validation bug?

This appears to be neither something you missed nor a bug, but in fact expected behavior (although stupid behavior it seems to be).

Check out lines 601-605 of Form_validation.php:

Code:

// If the field isn't required and we just processed a callback we'll move on...
if ( ! in_array('required', $rules, TRUE) AND $result !== FALSE)
{
    return;
}

Apparently, if the field isn't required and a callback was processed, they finish processing right after that. Or maybe they meant to put continue instead of return, and it is a bug.

So, I suppose you could just replace that return with a continue.
