HI Adriano, I'm also trying out the views for Form30 (Cases) for which the auto assigning of the Related Content is already working but can't seem to get the view to work.
I have Parent Post "FinancialAidSchool" (under Type "Relationship") and Child Post "example1", "example2", "example3" (under Type "Cases").
In the "example1" page, I want to add a Related_Content view that will display "example2" and "example3" as well, since they share the same parent "FinancialAidSchool".
I'm trying to follow the guide you gave – http://wp-types.com/documentation/user-guides/many-to-many-post-relationship/
But I don't understand this part – Create a View that loads all the appearances that belong to the Event:
When you create this View, remember that we’re querying the intermediary post. In our case – appearances. Add a filter for event parent, selecting ‘Post where this View is inserted’. This will keep just the appearances that belong to the displayed event.
I query "Relationship" and add the filter Post Relationship – Post is a child of: Post where this View is inserted
But, I get the error message Post type Relationship doesn't belong to any other post type…?
I think the solution is to add a filter that says Post Relationship – Post is a PARENT of: Post where this View is inserted….but I don't think there is such an option?
