Yes, but the ValueChangeEvent will be processed in the Process
Validations phase, after submitting the form. So if you want to change
the value of the other inputText when the first changes, you need to
submit the form (technique #1). Otherwise, you can use javascript if
it is an option to you (if you don't have to process the form).
Hope it is clear now,
Bruno
