This is i think your mistake:
_tabbedPane = new HtmlPanelTabbedPane();
_tab = new HtmlPanelTab();
Never construct an UIComponent directly. It's lifecycle has to be
managed by the JSF engine for things to work properly. If you need to
create compoment using java code, use the application, like this:
Application application =
FacesContext.getCurrentInstance().getApplication();
_tabbedPane =
(HtmlPanelTabbedPane)application.createComponent(HtmlPanelTabbedPane.COMPONENT_TYPE);
