Hi @snixx
I’ve just tested it on my installation and it was working on my drafted custom post type, both the add_row() and get_field() functions.
Did you add the new post programmatically? If you did, it’s possible that your post doesn’t have the repeater value in the database yet. Keep in mind that the add_row() function will only add a row to an existing repeater. I think you can use the update_field to add an empty value. This page should give you more idea about it: http://www.advancedcustomfields.com/resources/update_field/.
Hope this helps.
