getSource() method of Listener

Hi,

I have a problem related to listener

  1. I have 1 button and 3 TextFields and one combobpx
  2. On the 3 text fields and combobox i had added the listeners(ValueChangeListener). For each textfield on clicking enter key each method need to call
  3. But inside [code]
    public void valueChange(ValueChangeEvent event) {

[/code]
I cant identify each textfields and combobox inside this method
4) How it can be accomplished

There is several ways to do this. You can find nice examples from the book of Vaadin. I recommend to read through
