Terms not retreived

Actually I'm not sure if it is a opencalais bug, or an interaction with one of the multiples module I use.

The problem is that loaded_node is wrong, and drupal_render($loaded_node->content) does not return anything
My modification bellow is wrong, since it load a previously saved version of the node, but that the "$node" passed as parameter does not contain the body anymore ...
but at least I can get some keywords now ...

function calais_process_with_calais(&$node) {
// #412796: This was changing $node->body w/o the clone

$loaded_node = node_load($node->nid); // REMOVED node_build_content(drupal_clone($node));//
$body = $body = strip_tags($loaded_node->body); // REMOVED strip_tags(drupal_render($loaded_node->content));

$date = format_date($node->created, 'custom', 'r');
// Allow modification of the content sent to Calais
drupal_alter("calais_body", $body, $loaded_node);
if (!is_calais_api_key_set()) {
$node->calais->service = NULL;
return array();
}

$calais = new Calais();
$keywords = $calais->analyzeXML($node->title, $body, $date);
//drupal_set_message("keywo

".print_r($keywords,true)."$body

");
$node->calais->service = $calais;

return $keywords;
}
