This is incorrect. You only need the reference in your class if you
need to do something with the component object. You only need to
provide a t:id if you need to refer to it later. Having the <a
t:type="eventlink">, or <t:eventlink> is enough to get the component
embedded in your page.
public Object onMenuEvent(int context) {
... get new results per the context...
return resultsZone.getBody();
}
with my menu like:
<li>
<t:eventlink event="menuevent" context="literal:1" zone="resultsZone">...
</li>
<li>
<t:eventlink event="menuevent" context="literal:2" zone="resultsZone">...
</li>
