Or do you mean via JavaScript and Prototype, e.g. $('myTextFieldID').value =
'whatever';

Yes, the value parameter is mandatory. That' tells Tapestry where to store the
value. As noted earlier you can use regular HTML input fields to avoid this,

Tapestry wouldn't be very useful if you couldn't transfer client input.
However, there are a few ways of doing it depending on what the goal is.
