    <p>The getSelectedProperty <code>Callback</code> parameter of <code>CheckBoxListCell.forListView()</code> is bound bidirectionally,</p> <blockquote> <p>(meaning that the CheckBox in the cell will set/unset this property based on user interactions, and the CheckBox will reflect the state of the ObservableValue, if it changes externally).</p> </blockquote> <p>Thereby adding a change listener to the <code>Card.selectedProperty()</code> may be more accurate, covering the external modification by both checkBoxes and other controls/setters.</p> <pre><code>final IntegerProperty count = new SimpleIntegerProperty(0); Text text = new Text("-"); // Bind count to text, to show on scene. text.textProperty().bind(count.asString()); ChangeListener listener = new ChangeListener&lt;Boolean&gt;() { @Override public void changed(final ObservableValue&lt;? extends Boolean&gt; observable, Boolean oldValue, Boolean newValue) { count.set(count.get() + (newValue ? 1 : -1)); if (count.get() &gt;= 10) { System.out.println("exceeded max limit"); // Revert selection Platform.runLater(new Runnable() { @Override public void run() { ((BooleanProperty) observable).set(false); } }); } } }; for (final Card card : cards.getItems()) { card.selectedProperty().addListener(listener); } </code></pre> <p>At the end of the user work, remove the listeners.</p> <pre><code>for (final Card card : cards.getItems()) { card.selectedProperty().removeListener(listener); } </code></pre> <p>Alternatively, if you strictly want to add listeners to checkboxes only, you can create custom ListCell having checkboxes internally and set a ListView.cellFactory().</p>

    1. COThe javafx api for the ChangeListener states, "In general is is considered bad practice to modify the observed value in this method." -http://docs.oracle.com/javafx/2/api/javafx/beans/value/ChangeListener.html Is there another way around editing the observable value, or is this the best option?

    2. CO@jwill, the value is not being changed in the method. It is changing in a new Runnable, later after exiting the method. The code in the Runnable triggers another changelistener event.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
