Descriptions

The describedAs() element is used to provide a short description of the property to the user.

In the Web UI (Wicket viewer) it is displayed as a 'tool tip'.

For example:

public class Customer {

    @PropertyLayout(
        describedAs = "The name that the customer has indicated " +
                      "that they wish to be addressed as " +
                      "(e.g. Johnny rather than Jonathan)")
    private String firstName;

    // ...
}
