Get the displayed node of a commerce_line_item in a component rule using ‘commerce_display_path’, doesnt work

I ve found something quite interesting in an other post Discount based on a field in product display node in Drupal Commerce?

It describe a way to get the ‘node display’ associated with a line_item

  1. Build a component rules action set with custom php code in it,
    providing a ‘node_fecthed’ provider variable and then use it with
    other rules to do what you need.
  2. The php code use the commerce_display_path backlink exploded url to find the displayed
    node, then return it.
  3. The given code is the following :

    $line_item_wrapper = entity_metadata_wrapper('commerce_line_item', $line_item); 
    $url = $line_item_wrapper->commerce_display_path->value(); $url_parts = explode('/', $url); 
    $nid = $url_parts[1]; 
    return array('node_fetched'=> $node);
    

Just before the return line, i added, regarding to a comment suggestion from the original post, 2 lines :

$node=node_load($nid);
dpm($node);

when rules is run, devel dpm() displays the right associated node as expected.
But when in an other rules i try to display/debug/use the ‘node_fetched’ it appears to do nothing as if it was set to null.
What may be wrong with that ?
Any suggestions will be appreciated as i’m going mad with that for 2 days.
Thx
