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);
}

> Hi! It is a good idea to add method like addMessageFromBundle that
> does something like this:
> public void addMessageFromBundle(UIComponent component,String
> bundleMessageKey) {
> ResourceBundle bundle = null;
> try {
> bundle = ResourceBundle.getBundle(getFacesContext()
> .getApplication().getMessageBundle());
> String message = bundle.getString(bundleMessageKey);
> error(componeng,message);
> } catch (MissingResourceException e) {
> e.printStackTrace();
> }
> }
> ==========
> 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.
