	public Panel getPanel() {
		logger.debug("panel privateChatBean " + this );
		Application application = FacesContext.getCurrentInstance()
				.getApplication();
		TabView tabView = (TabView) application
				.createComponent("org.primefaces.component.TabView");
		FacesContext facesContext = FacesContext.getCurrentInstance();
		FaceletContext faceletContext = (FaceletContext) FacesContext
				.getCurrentInstance().getAttributes()
				.get(FaceletContext.FACELET_CONTEXT_KEY);
 
		Set cles = session.getCalledUserList().keySet();
		Iterator it = cles.iterator();
 
		logger.debug("session size " + session.getCalledUserList().size() );
		while (it.hasNext()){
			String name = (String) it.next(); 
			User userForComponent =  (User) session.getCalledUserList().get(name); 
			logger.debug("session parcours " + name );
			CustomTab tab = new CustomTab();
			tab.setTitle(userForComponent.getName());
			tab.setId(name);
			tabView.getChildren().add(tab);
 
		logger.debug("session return " + tabView.getChildren().size() );
		panel.getChildren().add(tabView);
		return panel;

Je pensais que rerender suffisait pour mettre à jour mon panel mais apparemment non.

Merci beaucoup
