UUID services does not properly set node author.

This is correctly handled in the standard _node_resource_create() where the 'name' and 'language' are added inside the function. Now that uuid_service module uses _node_resource_update() instead, we can also add the missing values using the standard hook_entity_presave() function:

/**
 * Implements hook_entity_presave().
 */
function mymodule_entity_presave($entity, $type) {
  if ($type == 'node' && $entity->is_new && $entity->uuid_services) {
    if (empty($entity->uid)) {
      global $user;
      $entity->uid = $user->uid;
      $entity->name = $user->name;
    }
    if (!isset($entity->language)) {
      $entity->language = language_default('language');
    }
  }
}

I agree with aoturoa's suggestion.

Changed to use hook_entity_presave().

Thanks for that patch. I've merged it. Closing

I realised after committing the change, that this logic belongs in node_entity_uuid_presave().

The attached patch resolves the problem.

Thanks for the review. Merging.
