Problem while getting the value of field

Hello,

As I used your module, I've noticed that the value of a content field is fetch through the node language

in contentapi_retrieve we have line 333;

$lang = $raw_node->language;

If I understand this schema https://drupal.org/files/Fieldlanguagevariants.png, it should be the language of the field rather than the language of the node when we fetch the value.

To fix this, I've used this piece of code to get the body of my page and that work
$body_language = field_language('node', $raw_node, 'body');

Can you confirm this is a bug or did I misunderstood the way this module work?

Thanks folks
