JPAContainer + Related tables

We are using the JPAContainer with good results.

Now we need to go a step deeper and display data from a n:1 relation in a table.

We have a table with projects, where each project has one address assigned.

How can I display the associated address details in a table, where we show one row per project?

Must be something like:

project.name, project.startdate, address.name, address.enterprise

But I can’t find the correct way to access those properties for the table data container…
