    copied!<p>I have spent hours looking how to solve this. When I try to get parent from a child all but it's id fields are empty. It just makes no sense. I am using PlayFramework 2.0.4 if that might indicate anything (besides a terrible choice of framework).</p> <p>TRoute.java (parent)</p> <pre><code>@Entity @Table(name="routes") public class TRoute extends Model { @Id public String route_id; public String agency_id; @Constraints.Required public String route_short_name; @Constraints.Required public String route_long_name; public String route_desc; @Constraints.Required public String route_type; public String route_url; public String route_color; public String route_text_color; @OneToMany(mappedBy="troute") public List&lt;Trip&gt; trips; public static Finder&lt;String, TRoute&gt; find = new Finder( String.class, TRoute.class ); } </code></pre> <p>Trip.java (child)</p> <pre><code>@Entity @Table(name="trips") public class Trip extends Model { @Constraints.Required public String route_id; @Constraints.Required public String service_id; @Id public String trip_id; public String trip_headsign; public String direction_id; public String block_id; public String shape_id; @ManyToOne @JoinColumn(name="route_id") public TRoute troute; public static List&lt;Trip&gt; byRouteId(String route_id) { List&lt;Trip&gt; trips = Trip.find .where().like("route_id", route_id) .findList(); return trips; } public static Finder&lt;String, Trip&gt; find = new Finder( String.class, Trip.class ); } </code></pre>
