JavaFx 2.1, 2.2 TableView update issue

Question

My application uses JPA read data into TableView then modify and display them. The table refreshed modified record under JavaFx 2.0.3. Under JavaFx 2.1, 2.2, the table wouldn\'t

Answer 1

looking into the TableView.java code, there's private refresh() which just executes

getProperties().put(TableViewSkinBase.REFRESH, Boolean.TRUE); 

At last, the code below worked for me(Java8). (be careful, the constant's name is not REFRESH but RECREATE)

tableView.getProperties().put(TableViewSkinBase.RECREATE, Boolean.TRUE);

(reading javafx's code, this will force cell re-creation)

Answer 2

this worked for me

@FXML 
private void refreshTableView()
{
  firstNameCol.setVisible(false);
  lastNameCol.setVisible(false);
  emailCol.setVisible(false); 
  firstNameCol.setVisible(true);
  lastNameCol.setVisible(true);
  emailCol.setVisible(true);
} 

Answer 3

See the answer to Updating rows in Tableview. Add these getters and it will just work.
Additionally since the data is an ObservableList which is set as items to tableView, any changes to this data list will be reflected to the table.getItems() too. Namely no need to table.setItems(data) again.

Answer 4

I have found a simple workaround for triggering the refresh of the TableView in JavaFX 2.1 TableView refresh items. It solved the issue for me.

Add this to your code:

tableView.getColumns().get(0).setVisible(false);
tableView.getColumns().get(0).setVisible(true);

Answer 5

I had the same problem and after some search this is my workaround. I found that if the columns are removed and then re-added the table is updated.

public static <T,U> void refreshTableView(final TableView<T> tableView, final List<TableColumn<T,U>> columns, final List<T> rows) {
    if (tableView == null) {
        throw new NullPointerException();
    }
    if (columns == null) {
        throw new NullPointerException();
    }
    if (rows == null) {
        throw new NullPointerException();
    }

    tableView.getColumns().clear();
    tableView.getColumns().addAll(columns);

    ObservableList<T> list = FXCollections.observableArrayList(rows);
    tableView.setItems(list);
}

Example of usage:

refreshTableView(myTableView, Arrays.asList(col1, col2, col3), rows);

Answer 6

Notification-based updates of JavaFX controls typically require that the properties of the data model object backing your GUI meet the minimum definition for a JavaFX Bean.

The following exemplifies the minimum code needed in order for a JavaFX property to satisfy these requirements:

public class Client extends DB {

    private IntegerProperty id =         new SimpleIntegerProperty();
    private StringProperty  lastName =   new SimpleStringProperty();
    private StringProperty  firstName =  new SimpleStringProperty();


    public final int getID() {return this.id.get(); }
    void setID(int id) { this.id.set(id); }
    public final IntegerProperty idProperty() { return this.id; }

    public final String getLastName() { return this.lastName.get(); }
    public final void setLastName(String ln) { this.lastName.set(ln); }
    public final StringProperty lastNameProperty() { return this.lastName; }

    public final String getFirstName() { return this.firstName.get(); }
    public final void setFirstName(String fn) { this.firstName.set(fn); }
    public final StringProperty firstNameProperty() { return this.firstName; }
    :
    :
}    

Glancing over your code, it does not appear that your properties satisfy the requirements for a JavFX Bean. As such, automatic notification-based updates will not occur.
