Thanks, findComponent() was pretty easy, unless I goofed:
(in action method)
UIViewRoot root = FacesContext.getCurrentInstance().getViewRoot();
HtmlSelectOneListbox listBox =
(HtmlSelectOneListbox)root.findComponent("form:id");

The best way to do it is to use
<component binding="#{yourBean.component}" ....
on your page.
This only works if you're referencing the component from the same bean every
time (which is generally the case).
Otherwise, you need to use findComponent() or invokeOnComponent(), which is
a lot more involved.
