Answer 1

With <f:ajax>, JavaScript is used to locate elements in the HTML DOM tree and re-render them. But if a JSF component is not rendered into the HTML output, then there's also nothing in the HTML DOM tree to re-render. You should either re-render its closest parent component which is always rendered instead, or wrap it in another component (e.g. <h:panelGroup>) which is always rendered and re-render it instead.
