Sending a redirect from inside an ajax listener method

Question

This question is closely related to this one (which has been answered).

Throughout my project, I navigate between screens using JSF command buttons, where the action attribute would point to a function that returns a string. The string is the new screen's name e.g.

<h:commandButton value="Select" action="#{searchResultsBundledBean.selectFlight}">
</h:commandButton>

selectFlight would return a string, e.g. selected-flight-review which would direct the user to selected-flight-review.xhtml

For mobile purposes I had to make a panelGrid clickable using an ajax call, e.g.

<h:panelGrid>
    <f:ajax event="click" listener="#{searchResultsBundledBean.clickFlight(lowFareBundledSearchItem)}"/>
 </h:panelGrid

This works, I've tested it, and the correct result is returned(Tested with logging it right before it's returned)

However, no redirection takes place. The ajax call doesn't do it yet. How do I make it redirect to another screen? I don't have to send through any variables, I just need the new screen to be displayed. Should I use something other than ajax(I would prefer not to), or is there some way to make this work the way it is now?

You can redirect the response from the backing bean:

public void clickFlight(Item lowFareBundledSearchItem) throws IOException {
    // ...
    FacesContext.getCurrentInstance().getExternalContext().redirect("selected-flight-review.xhtml");
    FacesContext.getCurrentInstance().responseComplete();
}
