Xpath query only working for create, not update

Hi,

I trying to create a set-up that allows for multiple blogs. Each blog will have it’s own author section. When selecting an author for a blog article you should only be able to select an author for that specific blog. This is the xpath query that I’m using at the moment, it allows me to only select authors for that specific blog when creating a new post. However, when I try to update the author of a blog article it allows me to select from all authors.

$parent/../../child::*[BlogAuthorPage]

Hope that makes sense. Any help is appreciated. Thanks.
