I don't know exactly what you need it for, perhaps something like this could
work:
instead of , you use
public String getValue()
{
return getYourObject().getValue();
}
// Called on form submit
public void setValue(String value)
{
if (!value.equals(getYourObject().getValue))
Oups, sorry, i did not see the component specification ...

Here you go, it's for Tap4 btw:
Usage example:
value is the property to watch, listener will be called at the end of the
rewind
cycle, if the prop did change.

Hmm. Maybe I misunderstood you.
When you enter a value into a field in the page, tapestry will call to the
getter for that variable when the page render, and the setter of the
variable (with you entered value) when you submit the form of which the (I
assume) TextField is a part, like;
..
publ
Yes i could ...
but it looks like an elephant gun just to keep the trac of an old value
that Tapestry has to know ... but where ? :-\

Then you can save the latest or last value in that object, wh
tener 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.

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 ...
Hi all,
I need to get the old value of a form field in the listener of this form
but i can't get this value before it's been updated with the data
submitted by the client ...
Any idea is welcome !
