[Groovy] Class StartupUriFragmentUtility

java.lang.Object
  com.vaadin.ui.AbstractComponent
      com.vaadin.ui.UriFragmentUtility
          org.grails.plugin.vaadin.ui.StartupUriFragmentUtility

class StartupUriFragmentUtility
extends UriFragmentUtility

A special UriFragmentUtility that forces the browser to send the initial fragment only when the application first starts. Thereafter, it behaves exactly like the UriFragmentUtility.

Note that UriFragmentUtility will not send a fragment changed event if the server-side fragment is the same as the browser-side fragment. This means that we don't get any fragment information when the app first starts. This class is designed to get around that by forcing the browser to send its fragment when the app first loads.
