[JSF 2] internationalization: UPDATE_MODEL_VALUES et INVOKE_APPLICATION phases are skipped

[Celinio Fernandes]

Hi,
I have this <h:selectOneMenu> tag where the user can change the language.

<h:selectOneMenu value="#{loginBean.langue}"  valueChangeListener="#{loginBean.changerLangueComboBox}" onchange="submit()" >
      		 <f:selectItem itemLabel="Langue" itemValue="langue"/>
      		 <f:selectItem itemLabel="Français" itemValue="fr"/>  
	         <f:selectItem itemLabel="Anglais" itemValue="en"/>  
      </h:selectOneMenu>

Here is the method of the managed bean :

public void changerLangueComboBox(ValueChangeEvent event) {
		FacesContext context = FacesContext.getCurrentInstance();
		if ("en".equals((String) event.getNewValue())){
			 context.getViewRoot().setLocale(Locale.UK);
			 this.locale = Locale.UK;	
		} else  if ("fr".equals((String) event.getNewValue())) {
			 context.getViewRoot().setLocale(Locale.FRENCH);
			 this.locale = Locale.FRENCH;	
		} 
		log.info("context.getViewRoot().getLocale() is : " + context.getViewRoot().getLocale());
	}      

The method is called but the values of the current view are not updated. They are updated if i refresh the page.
Here are the sequence of phases calls :
1) User changes the language :

20:11:18,127 INFO  [STDOUT] Processing new  Request!
20:11:18,128 INFO  [STDOUT] before - RESTORE_VIEW 1
20:11:18,141 INFO  [STDOUT] after - RESTORE_VIEW 1
20:11:18,141 INFO  [STDOUT] before - APPLY_REQUEST_VALUES 2
20:11:18,141 INFO  [STDOUT] after - APPLY_REQUEST_VALUES 2
20:11:18,141 INFO  [STDOUT] before - PROCESS_VALIDATIONS 3
20:11:18,142 INFO  [LoginBean] context.getViewRoot().getLocale() is : fr
20:11:18,142 INFO  [STDOUT] after - PROCESS_VALIDATIONS 3
20:11:18,143 INFO  [STDOUT] before - RENDER_RESPONSE 6
20:11:18,150 INFO  [STDOUT] after - RENDER_RESPONSE 6
20:11:18,150 INFO  [STDOUT] Done with Request!

2) User refreshes the page :

20:11:37,402 INFO  [STDOUT] Processing new  Request!
20:11:37,402 INFO  [STDOUT] before - RESTORE_VIEW 1
20:11:37,417 INFO  [STDOUT] after - RESTORE_VIEW 1
20:11:37,417 INFO  [STDOUT] before - APPLY_REQUEST_VALUES 2
20:11:37,418 INFO  [STDOUT] after - APPLY_REQUEST_VALUES 2
20:11:37,418 INFO  [STDOUT] before - PROCESS_VALIDATIONS 3
20:11:37,419 INFO  [STDOUT] after - PROCESS_VALIDATIONS 3
20:11:37,419 INFO  [STDOUT] before - UPDATE_MODEL_VALUES 4
20:11:37,419 INFO  [STDOUT] after - UPDATE_MODEL_VALUES 4
20:11:37,419 INFO  [STDOUT] before - INVOKE_APPLICATION 5
20:11:37,420 INFO  [STDOUT] after - INVOKE_APPLICATION 5
20:11:37,420 INFO  [STDOUT] before - RENDER_RESPONSE 6
20:11:37,428 INFO  [STDOUT] after - RENDER_RESPONSE 6
20:11:37,428 INFO  [STDOUT] Done with Request!

Obviously, the UPDATE_MODEL_VALUES et INVOKE_APPLICATION phases are skipped.

Question : why are they skipped and how can i call them ?
Well I did manage to call these 2 phases with these 2 lines :
event.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
event.queue();
In that case all phases are called. Still, I need to refresh the page to get the chosen language.

Thanks in advance for helping.

I think a better way to do it would be to use the "locale" property of
<f:view>, like this:

<f:view locale="#{bean.locale}">

Then have the getter do whatever you need to do to look it up.

Would that work?

P.S. On 2 February, here on JavaRanch, I'm doing an event to promote my
new book, JavaServer Faces 2.0: the Complete Reference. Stay tuned for
details!

Well,
I already have that property set on the view. And the getter/setter on the bean.

I did as you suggested though and modified the locale in the getter :

   public Locale getLocale() {
		changeLanguage(eventStr); // method that sets the Locale, based on the selected language in the <:selectOneMenu> tag.		
		return locale;		
	} 	

I can see that it goes through all the phases but I still need to refresh the page to get the new values (different language).
