I used to run successfully the following custom PHP code in rules before a node is stored
$update_node = node_load($node->nid);
$lat1 = floatval($node->field_geo["und"][0]["lat"]);
//SOME MATH HERE
$update_node->field_winkel_dorf["und"][0] = array("value"=>$winkel);
node_save($update_node);
}
But now after a major update of lots of modules I get this error: EntityMalformedException: Fehlende Paketeigenschaft auf einem Element des Types node. in entity_extract_ids() (Zeile 7663 von /var/www/vhosts/mydomain/httpdocs/includes/common.inc).
I have no idea what changed....
Any help very very welcome.
