[Technical-Support] LPS-49010 The given error message isn't shown when moving a "Link to a Page of This Site" to the first position

Hi Peter,

My solution are three parts:

1. A new service  method. We need it to avoid inconsistent layout. Without it LayoutService always update layout despite priority update will be failed.
2. Simple regeneration.
3. We need to put back dragged layout to original position based on response object. 
 
Please ask me if you would be any question.

Thanks,
 Zsaga
