Sure, couldn't they? I'm not sure why they are split up into the two
different event handlers. Except in the case of action links and form
submission both the onAction and beginRender events are going to fire
in a request. You haven't mentioned a need to do anything different
with the information between when the two events fire, so why not
handle it in one place?
Or am I missing something?
