show column from another entity

Hello: A want to show in a dataGrid a column from other entity so i added a new column in the page and select it from dataSource → Attribute:   But the column didn´t show the data:   Must i changed some other property or add a new association on the domain model?   Thanks in advance.   Regards.

Hello Again, i found the problem.

When I am creating the new game object  i´m creating it without a reservation number and that´s why the column appears void.
