This thread is resolved. Here is a description of the problem and solution.

Problem: I would like to create a list of posts that are related to the current post. The posts are all in the same post type.

Solution: In the current system, the best way to do this is to use a custom taxonomy that includes terms that match the slugs of each post. For example, you have Post A and Post B that should be related to each other. So you create terms "post-a" and "post-b" in a custom taxonomy. Then you add the term "post-b" to Post A, and you add the term "post-a" to Post B.
Then create a View of this post type, filtered by taxonomy term slug, where the slug is set by a shortcode attribute "wpv-related-posts". In the Loop Output of this View, insert a post link with the wpv-post-link shortcode.
Pass the current page's slug into this shortcode attribute using the wpv-post-slug shortcode, like this:

[wpv-view name="your-view-slug" wpv-related-posts="[wpv-post-slug id='$current_page']"]

Hi, there is not currently a built-in way to select other posts from the same post type like this in custom field values. The best way to do something similar is to use a custom Taxonomy to relate posts. In your new Taxonomy, create a term that matches the slug of the current post, and assign that term to any post you want to see on the current post as a related post link. For example, let's say you have Post A and Post B, whose slugs are "post-a" and "post-b". You want to show Post B as a related post link on Post A, and vice versa. Let's assume your custom Taxonomy is called "Related-Posts". Edit Post A and add the term "post-b". Edit Post B and add the term "post-a".

Next, create a new View of this post type, filtered by Related-Post taxonomy term slug, set by a shortcode attribute like "wpv-related-post". Insert this View in your Content Template or Template Layout for this Post type using a shortcode. Pass the current post's slug into the wpv-related-posts filter like this:

[wpv-view name="your-view-slug" wpv-related-posts="[wpv-post-slug id='$current_page']"]

Now your View will show all the posts related to the current post. This relationship is not automatically reciprocal, so you must relate Post A to Post B, and also relate Post B to Post A, in order for the links to appear on both posts.
