OK, makes sense, esp. because I already did that in other places.
So, I changed the code to:
public HtmlPanelTabbedPane getTabbedPane() {
if (_tabbedPane == null) {
Application app = FacesContext.getCurrentInstance().getApplication();
_tabbedPane =
(HtmlPanelTabbedPane)app.createComponent(HtmlPanelTabbedPane.COMPONENT_TYPE);
_tab = (HtmlPanelTab)app.createComponent(HtmlPanelTab.COMPONENT_TYPE);
_tab.setLabel("Blah");
_tab.setId("PanelTab");
_tabbedPane.getChildren().add(_tab);
_tree = (HtmlTree)app.createComponent(HtmlTree.COMPONENT_TYPE);
....
But the behaviour did not change :-( Anything else suspicious?
TIA,
Uli
