public class PasswordField
extends AbstractTextField

A version of TextField, but rendered out as an <input type="password"> element. Further, the output value for a PasswordField is always blank. When the value provided to the PasswordField is blank, it does not update its property (care should be taken that the "required" validator not be used in that case).

Includes the size attribute, if a Width annotation is present on the property bound to the value parameter.
