[jira] Commented: (SHALE-269) Convenient programmatic access to localized messages

["Adrian Mitev (JIRA)" <ji...@apache.org>]

    [ http://issues.apache.org/struts/browse/SHALE-269?page=comments#action_38200 ] 
            
Adrian Mitev commented on SHALE-269:
------------------------------------

A good idea too is to add method for error message using the component id instead of the component object. Thisway the developer won't need to have a binding to the component only to add an error message. Also method for finding component in the root will be useful:

public static UIComponent findComponentInRoot(String id) {
   return getFacesContext().getViewRoot().findComponent(id);
}

Methods for navigation:

public void gotoView(String viewName) {
    if (viewName!= null) {
      UIViewRoot view = getApplication().getViewHandler().createView(getFacesContext(),viewName);
      getFacesContext().setViewRoot(view );
    }
}

public void navigate(String fromView,String outcome) {
  getApplication().getNavigationHandler().handleNavigation(getFacesContext(),fromView, outcome);
}

> We might also look at ways to provide for parameter replacement in such messages.
> Seam also has a cute utility that lets you build messages out of EL expressions for parameter replacement.
