Additional configuration is only needed if you want to change the default behaviour.
For example, a Date Time Field must respond if we change something inside its text field or if we change hours or minutes through its internal text fields, or AM/PM through its internal drop down choice.
It consists of a page with two elements: a dropdown menu and a label.
When the dropdown selection changes, the label (and only the label) will be updated.
The mechanism by which modifying a Java object translates to a change in the web page happens behind the curtains and is not relevant to the developer.
Wicket offers a big set of AJAX-enabled components out-of-the-box.
