Hey guys. The explorer for GXT 3.0.0 is quite straight forward when it comes to this. Nothing special. Still, I am having problems to make it work on my simple test case. Strangely enoug, something similar worked for me in GXT 2.2.6.

Here is the entry point code:
Code:
public class StartPoint implements EntryPoint
{
    private Button clickMeButton;
    public void onModuleLoad()
    {
        RootPanel rootPanel = RootPanel.get();
        
        clickMeButton = new Button();
        rootPanel.add(clickMeButton);
        
        final FadeMe panel = new FadeMe();
        rootPanel.add(panel);
        
        clickMeButton.setText("Click me!");
        clickMeButton.addClickHandler(new ClickHandler()
        {
            public void onClick(ClickEvent event)
            {
                panel.getElement().<FxElement>cast().fadeToggle();
            }
        });
    }
}
And this is the FadeMe class definition (reduced but still the same concept that I am using):
Code:
public class FadeMe extends ContentPanel
{    
    private VerticalLayoutContainer container;
    private TextField txtSubject;
    private TextArea txtDescription;
    
    public FadeMe()
    {
        container = new VerticalLayoutContainer();
        
        Label lblSubject = new Label("Subject");
        container.add(lblSubject);
        
        txtSubject = new TextField();
        container.add(txtSubject);
        
        Label lblDescription = new Label("Description");
        container.add(lblDescription);
        
        txtDescription = new TextArea();
        container.add(txtDescription);
        
        this.add(container);
    }
}
What am I missing here? The problem is that fade is not there. The panel shows and hides, but without fade effect. Just pops in and out.

Thank you!
