Answer 1

I got the solution. Go to classes >> controller >> AdminController.php

See the function copyFromPost

Find,

$languages = Language::getLanguages(false);
$class = get_class($object);
    $fields = $class->$definition['fields'];

    foreach ($fields as $field => $params) {
        if (array_key_exists('lang', $params) && $params['lang']) {
            foreach ($languages as $language) {
                if (isset($_POST[$field.'_'.(int)$language['id_lang']])) {
                    $object->{$field}[(int)$language['id_lang']] = $_POST[$field.'_'.(int)$language['id_lang']];
                }
            }
        }
    }

Replace with,

$rules = call_user_func(array(get_class($object), 'getValidationRules'), get_class($object));
    if (count($rules['validateLang']))
    {
        $languages = Language::getLanguages(false);
        foreach ($languages as $language)
            foreach (array_keys($rules['validateLang']) as $field)
                if (isset($_POST[$field.'_'.(int)$language['id_lang']]))
                    $object->{$field}[(int)$language['id_lang']] = $_POST[$field.'_'.(int)$language['id_lang']];
    }   

Answer 2

The link_rewrite element is also language dependent. Try replacing:

<link_rewrite>hello</link_rewrite>

with:

<link_rewrite>
    <language id="1">hello</language>
    <language id="2">hello</language>
</link_rewrite>
