Drupal 7: Help me to wrap my head around EVA/reverse node reference
OK, i did it. Here's how:

Node types:
I've set up 2 node types "article" and "theme week".
"theme week" has a node reference field where nodes of the type "article" can be choosen.

View:
 - I've set up one "EVA" view (requires EVA) Under "advanced", I've
   selected the relationship to my "article" node type. 
 - I did NOT set "require relationship". 
 - Unter "contextual filter" I've set "Content: Nid", "Provide default value -> Content ID from URL".
 - I've set all my fields and filter criteria to use that relationship

Display Suite/EVA: - I've attached my View as a field in my "theme week" node type (requires Display Suite/DS).

Now when a "theme week" node is viewed, it shows the "article" nodes which have been referenced by "theme week".

I hope this might be useful to someone!
