/**
 * This method handles the state of the <code>JLabel</code>'s that are associated to mandatory fields, as well as
 * any 'special' component. It is called via two tracks: Once by the implementation of the
 * <code>BindingListener</code> in <code>BindingManager</code> and once by individual action listeners for each
 * component. These action listeners are installed at the same time of the installation of the binding (cf.
 * BindingManager.setupComponent())./*w  ww  . j a v  a  2 s . c  o  m*/
 *
 * @param component the component
 * @param failure if the label should express a failure
