u can use fireChangeEvent.

like that:

Code:

public class WizWizardPanel1 implements WizardDescriptor.Panel {

    private WizVisualPanel1 component;
    private final Set<ChangeListener> listeners = new  
    HashSet<ChangeListener>(1);
    
    public Component getComponent() {
        if (component == null) {
            component = new WizVisualPanel1();
            
        }
        return component;
    }
    
    public boolean isValid() {
        if(component == null){
            return false;
        }
        if ((component.getLbl1().getText().length()== 0) && 
                (component.getLbl2().getText().length() == 0)){
            return true;
        }
        return false;
    }
    
    public final void addChangeListener(ChangeListener l) {
        synchronized (listeners) {
            listeners.add(l);
        }
    }
    public final void removeChangeListener(ChangeListener l) {
        synchronized (listeners) {
            listeners.remove(l);
        }
    }
   
    //firechange event calls to  isValid from stateChanged. if Valid is true, 
    //fireChange enable next o finish button.

    protected final void fireChangeEvent() {
        Iterator<ChangeListener> it;
        synchronized (listeners) {
            it = new HashSet<ChangeListener>(listeners).iterator();
        }
        ChangeEvent ev = new ChangeEvent(this);
        while (it.hasNext()) {
            it.next().stateChanged(ev);
        }
    }             
    
}

i let U here the Tom Wheeler´s site, where U can find a little example:
Tom Wheeler's NetBeans Site

it´s a little confusing, but not so hard (unless u play with wrappers like me, but it´s another issue. Nothing to do with this... ).
