Yes thanks,
I've done this first of course.
It's a start but it does not bring so much light in my point of view.
For instance :
it does not say what's the difference between calling formSupport.defer
or heartbeat.defer, do you see the difference and the conscequences on
request treatment or event treatment ?
If you look at this exemple : TreeGridComponent
http://tapestry5-treegrid.googlecode.com/svn/trunk/tapestry5-treegrid/src/main/java/org/codelutin/tapestry/components/TreeGrid.java
a hearbeat.begin is called in beginRender and heartbeat.end is called in
afterRender but you can never read a call to defer, so can you explain
why the author of this component call begin and end ? I really can't
explain myself.
What's going on if many components on a page use heartbeat, each
component have its own heartbeat system, or is there a general heartbeat
rythm, and each component register to it through the call to begin, end
and defer ? Can two different heartbeat join and in which circumstances?
Especially if a componnent contains another component ?
Mybe heartbeat is something very simple and the word "heartbeat" make me
think it's bigger but I don't find that so clear when I start to read it
in real components.

Hi list,
As I start to read the code on components I often see heartbeat
@Environmental
private Heartbeat heartbeat;
with heartbeat.begin and heartbeat.end
Can someone explain the role of this object and its methods invocations
(begin and end) beacause it's not really clear in my mind.
Thanks a lot.
