/**
 * This method is only called when non-scripted mode is used to update the UI. This basically exists to support
 * the PFG (POST/FORWARD/GET) pattern that allows to use the browser back button without POSTDATA warning from the browser
 * and to re-initialize the preceding form (if any).
 * <p/>// w  w  w . j a  v  a  2 s . c  o  m
 * To make sure that an update is requested from the XFormsSession and not by the user clicking the reload button the
 * XFormsSession holds a property XFormsSession.UPDATE_REQUEST when coming from XFormsSession. If this property exists,
 * the UI is refreshed otherwise the form is re-inited with a GET.
