~~Title: Ignore Navigation for Specific Screens~~

It's super easy to enable standard Browser navigation for an application. Simply set the application parameter

<file script>
Application.navigation
</file>

to **true**.

If navigation is enabled, it's possible to use the browser buttons, Back and Forward, to navigate between your screens. But sometimes, you don't want navigation for specific screens, e.g. open a screen as modal "popup". The modal popup is just a detail of another screen and not a real navigation target.

It's possible to disable navigation for screens. You have different options:

  * Implement the interface ''com.sibvisions.apps.vaadin.IIgnoreNavigation'' in your workscreen class \\ //(best option for base workscreen classes)//
  * Add the annotation ''com.sibvisions.apps.vaadin.IgnoreNavigation'' to your workscreen class \\ //(good for specific workscreen classes)//
  * Set the parameter #IGNORENAVIGATION, e.g. \\ <file java>
HashMap<String, Object> mpParams = new HashMap<String, Object>();
mpParams.put("#IGNORENAVIGATION", Boolean.TRUE);
        
getApplication().openWorkScreen(StatusWorkScreen.class.getName(), Modality.Modal, mpParams);
</file> //(good for on-demand workscreens)//
