In order to make my Collections observable for JavaFX I used the JavaFX bean convention to wrap them in javafx.beans.Properties.
Hibernate is not able to refresh Entities with Collections ( ` {{ ElementCollection ` }} , ` {{ ManyToMany ` }} , ` {{ OneToMany ` }} ) correctly.
{code:Java}
@Entity
public class Person {
private int id;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public int getId() { return id; }
public void setId(int id) { this.id = id; }
private final ListProperty<String> contacts = new SimpleListProperty<>(FXCollections.observableArrayList());
public final ListProperty<String> contactsProperty() { return contacts; }
@ElementCollection
public List<String> getContacts() { return contacts.get(); }
public void setContacts(List<String> contacts) { this.contacts.set(FXCollections.observableList(contacts)); }
}
{code}
In this Example the ` {{ contacts ` }} are wrapped inside a ` {{ ListProperty ` }} , so the ui gets notified on changes. I provide JPA with property acces on the ` {{ getContacts() ` }} method.
All operations seem to work fine with the property access. It is possible to
- ` {{ persist() ` }} a ` {{ Person ` }} ( ` {{ contacts ` }} in the DB Table are being inserted)
- ` {{ find() ` }} a ` {{ Person ` }} (the ` {{ contacts ` }} are fetched correctly from the DB and are available in {{ contactsProperty() }} and {{ getContacts() }} )
- ` {{ flush() ` }} a change to a ` {{ Person ` }} ( ` {{ contacts ` }} are being updated in the DB Table correctly)
But it is not possible to ` {{ refresh() ` }} a ` {{ Person ` }} . The ` {{ contacts ` }} do not get updated. |
