RE: panelTabbedPane question

[James Richards]

Julian,

Thanks for the suggestion.  I changed the type to reference a backing bean 
which I had caused to implement TabChangeListener, unfortunately the listener 
tag's type attribute is expecting a classname:

// snip
  if (componentTag.getCreated())
        {
            //Component was just created, so we add the Listener
            UIComponent component = componentTag.getComponentInstance();
            if (component instanceof HtmlPanelTabbedPane)
            {
                String className;
                if (UIComponentTag.isValueReference(type))
                {
                    FacesContext facesContext = 
FacesContext.getCurrentInstance();
                    ValueBinding valueBinding = 
facesContext.getApplication().createValueBinding(type);
                    className = (String) valueBinding.getValue(facesContext);
                } else
                {
                    className = type;
                }
                TabChangeListener listener = (TabChangeListener) 
ClassUtils.newInstance(className);
                ((HtmlPanelTabbedPane) 
component).addTabChangeListener(listener);
            } else
            {
                throw new JspException("Component " + component.getId() + " is 
no HtmlPanelTabbedPane");
            }
        }
// end snip

accordingly a reference to a backing bean instance will not resolve to a proper 
String classname and will cause a class cast exception.  

The source code does make it clear that it is correct to place the 
tabChangeListener as a child of the HtmlPanelTabbedPane so I think that the 
problem is somewhere else.

Does anyone have an input as to why no tab change event is fired in 1.1.1?  

Thanks for the suggestion.

James

try using a value binding for the tabChangeListener handler eg.
<x:tabChangeListener type="#{myBackingBean}">

I have a tabbed pane with a tabChangeListener attached

<h:form id="dealForm">
        <x:panelTabbedPane id="dealTabbedPane"
                    selectedIndex="#{dealForm.activeTab}"
                    bgcolor="#eeeeee"
                    width="980"
                    activeTabStyleClass="tabActive"
                    inactiveTabStyleClass="tabActive"
                    serverSideTabSwitch="true">
                <x:tabChangeListener type="com.foo.listener.TabListener"/>

...
</h:form>

but on MyFaces 1.1.1, the TabListener's

  public void processTabChange(TabChangeEvent event) {
//...
  }

is not being invoked.  Is there something additional that need to be done to
enable the tab listener?

Thanks for any help,

James
