One thing that I found out rather later than I'd have liked to is that
you can access EL variables from the backing bean - and particularly
useful is that you can access a table iterator's current value e.g.
<h:table value="blah.values" var="item">
<h:outputText value="item.name"/> <h:commandLink
actionListener="#{blah.delete}" value="Delete"/>
</h:table>
I can get the value of 'item' in the actionListener using:
FacesContext fContext = FacesContext.getCurrentInstance();
VariableResolver requestResolver =
fContext.getApplication().getVariableResolver();
Blah blah = requestResolver.resolveVariable(fContext, "item");
Which I thought was pretty cool when I found out and meant that I didn't
have to fiddle around accessing it through a bound table control or a
data model.
Hope that's of some help.

What about something lik this:
<h:commandLink styleClass="table-header"
actionListener="#{inboxBean.sort}">
<f:param name="column" value="name"/>
</h:commandLink>
Usually you won't need using parameters though.
