I've set up these 2 objects:
- Book
- Author
A book has an author field.
I have one action:
- Read
I have 2 aggregations:
- Recently read books
- Favorite authors
The Favorite authors aggregation is set up to show author objects on the read action.
I posted a story to my Timeline: Felipe read "some book", but it only shows the Recently read books aggregation and not the Favorite authors.
How am I suppose to set up the aggregation for Favorite authors?
If the aggregation is setup correctly (you can test this by adding sample objects and actions in the aggregation configuration) then it will show up when there is enough data to build the aggregation.
As not all aggregations show on Timeline for all people, you can see how it appears for you by looking at your app timeline view. You can find this at https://www.facebook.com/YOUR_USERNAME/app_YOUR_APP_NAMESPACE
