This is wat I’m doing.
1. Go to projecten overview
2. Edit a post
3. Click on the ‘view all’ in the connection box
4. Than I click on the ‘+’ to add the connection
5. I see a connection in the meta box
6. Than I hit Update/save
7. The connection is gone (or actually never sent to the db)
When I check my database I only see a one way relationship i.e.
primaryId From To
1 489 909
Where as when I do it the other way around (edit a post in diensten) it does this:
primaryId From To
1 489 909
2 909 489
I’ve checked with other post types, nothing there..
