Thanks Marcus, I'm interested cause i'm really stuck with this problem ...
But i'm really surprised that Tapestry doesn't let us read the value
before it updates it ...

I've written a small component called @Watch for this.
It calls a given listener whenever a value is changed.
It uses a hidden field to submit the old value along with the new one.
If you're interested I could post the code.

Subject: Re: Retrieve the old value of a field in the form listener
Perhaps i took a wrong approach ...
In fact, i need to apply specific code if a particular field
of my form
has been updated and not in the other case. So i need to
compare the old
to the new value of this field but i can't find a way to get the old
value after the form has benn submitted ...

Any idea is welcome !
