My answer was related to Esther Leimbeck's question.
When using the updateActionListener nested inside a commandLink, the backing bean will automatically be updated.
Have a look at the Master-Detail example:

That's not what I'm asking though. I'm asking about how to use the
t:updateActionListener tag. I'm thinking the tag would be used inside of
a commandLink or commandButton tag and when the action is fired that the
link or button represents, it will automatically set and bean properties
of the backing bean backing that action? If so, this would be a SUPERBLY
nice feature.
Currently, for example if you pass in parameters with a commandLink you
need to do the following in the resulting action (assuming foo is the
f:param):
FacesContext context = FacesContext.getCurrentInstance();
Map map = context.getExternalContext().getRequestParameterMap();
String foo = (String) map.get("foo");
I'm assuming that possibly t:updateActionListener would avoid this
construct and that if you had a property in the Action called "foo" it
would be automagically populated using the tag. This would be very nice
- so nice, that I think it should be part of standard JSF.
