Hi Johann,
I am now back in office and I have tried to retest the latest version (snapshot) of geotoolkit-pending.

I get the same error as before, the cartography will not take effect and the variable "activepanel" is null when I press the "Apply-button".

The code fragment where I have the breakpoint is shown below:

Best Regards


* Property panel
 * @author Johann Sorel
* @module pending
public class JPropertyDialog extends JDialog{

    private JButton apply = new JButton(MessageBundle.getString("property_apply"));
    private JButton revert = new JButton(MessageBundle.getString("property_revert"));
    private JButton close = new JButton(MessageBundle.getString("property_close"));

    private JTabbedPane tabs = new JTabbedPane();
    private PropertyPane activePanel = null;
    private ArrayList<PropertyPane> panels = new ArrayList<PropertyPane>();

    /** Creates a new instance of ASDialog */
    private JPropertyDialog(final boolean modal,final boolean app, final boolean rev, final boolean clo) {

        JToolBar bas = new JToolBar();
        bas.setLayout(new FlowLayout(FlowLayout.RIGHT));



        tabs.addChangeListener(new ChangeListener() {
            public void stateChanged(ChangeEvent e) {
                activePanel = (PropertyPane)tabs.getSelectedComponent();

        apply.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) { // HERE THE activePanel is null ???????????????
                if(activePanel != null){

Hello Trond,

I will have a look at it, I don't think it will be long.

In our application "MapHandler" that heavily relies on the geotoolkit "Display swing widgets"-module we get an error that did not occur in earlier versions of geotoolkit.

It could be caused by error in our own code since we have done some rewriting, but I have a suspicion to the JPropertyDialog class.

In our example we want to change the colors of the polygons in a FeatureMapLayer. We opens the JSimpleStylePanel dialog and change the color (to red in this case) - see below.

The problem comes when the "Apply"-button is pressed. The action is trigged but the variable activePanel is null. The peculiar thing is that at first the activePanel is set to a correct value and then to null and of course when activePanel is not referening a JSimpleStylePanel then the "apply" method in that class is not performed and then nothing happens in the MapLayer.

Any hints would be appreciated !!

Best Regards
