Vaadin - data from multiple objects to Grid

I want to insert data from multiple objects (eg. from 2 Spring Data entities); I know how to make left join from multiple entities, but I'm not sure how to make Custom object from that...

In Vaadin Grid is typed using generics. For example: Grid<Person>. You cannot have multiple types here.

If you need to join data from multiple objects, you must create a middle layer to produce DTO (Data Transfer Object). The DTO collects properties from multiple source objects. This is a common practice in more complex business application, not limited to Vaadin.
