I have two entities and would show data from this in one table
In SQL I make this with the following SQL Statement:
Select werk., firma. From werk Inner Join firma On werk.firmaID = firma.ID
public class TestJoinTables extends Window {
private JPAContainer werkContainer;
public TestJoinTables() {
werkContainer = JPAContainerFactory.make(Werk.class, Schulung.PERSISTENCE_UNIT);
werkContainer.addNestedContainerProperty(“firma.name”);
Table filterTable = new Table();
// FilterTable filterTable = new FilterTable();
filterTable.setContainerDataSource(werkContainer);
…}
I think it should work with addNestedContainerProperty, but i get an error “Invalid property name”
How could I solve this problem? Should I use another Container?
In the attachment you could find my two entities, they have a @ManyToOne relation
