No Results Behaviour in Views

I just stumbled over this and decided to patch it up.
For now the "No Results Behavior" only works with another view with a entity reference display - and it's unlikely that we can change that.
The created code vastly bases on views_handler_area_view::render(). Unfortunately we can't re-use the method because we need access to the views object used to render, but the handler doesn't expose the object atm.

Works for me. Thank you.

Fixed an issue with the validator.

The 5 year old patch in #3 to EntityReference_SelectionHandler_Views.class.php and entityreference_plugin_display.inc does not apply to the latest 7.x-1.x-dev and if still relevant needs a reroll.

Checking patch plugins/selection/EntityReference_SelectionHandler_Views.class.php...
Hunk #1 succeeded at 130 (offset 21 lines).
error: while searching for:

      $entities = $this->view->execute_display($display_name, $args);
      $result = array_keys($entities);
    }
    return $result;
  }

Any update on this please?

I am facing similar issue, or is there any other workaround please.
