Joining sources in Aggregates

Joining sources in Aggregates

I did a scaffold to 2 screens. In the second screen's aggregate, I added 2 different entities as sources because I want some of their attributes shown in my second screen although they are not part of the entity I used to scaffold. I added these sources, and dragged and dropped some of the attributes from the 2 different entities in my table and form. Everything seems to be working fine, however, when I publish the table in my second screen is showing up empty. Even when I add stuff to it its still empty. If I take the sources off it starts populating again. How do I make my table populate with the added sources?

The fact that your table stays empty means that when adding the sources, you have some join conditions with "Only With", or perhaps some Filters, that restrict the query in such a way that there's no output. To fix it, debug your app to see what's going on (that's my advise in general: first debug your app before asking questions!).
