Tutorial, how to set values in entity reference field for the purpose of back reference
Motivation
I'm looking for a replacement module for the D7 entityreference_backreference: In my use case I have a content type with an entity reference field to a node of the same type. When I reference a node I want that the referenced node automatically references (back) the referencing node.
Proposed resolution
I imagine that this is no problem with ECA but I don't see how to do it. So if you're inspired to do a screen cast about this topic I'm sure this would help not only me.
