I'm using Drupal 7.x with Node Reference 7.x-2.0 and Corresponding Node Reference (CNR) 7.x-4.22. I need to use something that CNR offers, so I decided to test it using a vanilla installation of Drupal...

I created 2 content types (Content Type A and Content Type B). I then created 1 node reference field for which I tried to put on both content type pages. I then created 3 nodes within Content Type A, and 1 with Content Type B (both had no real content--just those fields).

In all of Content Type A's Nodes, I did not node reference anything... They were just blank nodes. But in Content Type B's node, I referenced all three of Content Type A's nodes...

The node reference links appropriately displayed from Content Type B's node page, but corresponding node links DID NOT appear on those 3 Content Type A pages...

You should only have to use 1 node reference field if they reference the EXACT same kind of resource (in my case, this was nothing more than a standard page). You shouldn't have to create 2 different fields for this, right?

Well, that's what I had to do in order to make CNR to work as expected...

Why?

(Hopefully this goes without saying that I love this module--but it would be awesome if you only had to use 1 CNR [node ref] field. In effect, creating nothing more than a "mirror" field of sorts.)
