Change Locale sequence

rengar Dec 22, 2006 2:33 AM

When change language, in an action in the same page catch old language, that have it before, with method "Locale.instance().getLanguage()"

I change language with localeSelector :

 <h:form id="selectLanguage">
 <h:selectOneMenu value="#{localeSelector.language}">
 <f:selectItems value="#{localeSelector.supportedLocales}"/>
 </h:selectOneMenu>
 <h:commandButton action="#{localeSelector.select}" value="#{messages['ChangeLanguage']}"/>
 </h:form>

After in action I have :

 String language = Locale.instance().getLanguage();

When change language the action is executed too.

I explain :

1º
View : Default "es" -> selectOneMenu = "español", properties = messages_es
Action : Locale.instance().getLanguage() = "es"

2º
View: Change "en" -> selectOneMenu = "English", properties = messages_en
Action: Locale.instance().getLanguage() = "es"

3º
View: Change "es" -> selectOneMenu = "español", properties = messages_es
Action: Locale.instance().getLanguage() = "en"

4º
View: Change "en" -> selectOneMenu = "English", properties = messages_en
Action: Locale.instance().getLanguage() = "es"
.
.
.
.

How change language before enter in my action?

Or any other idea?

Thanks.

Huh? I don't really understand, can you show the code where you call the action and the whole of the action.

When I change language the page is reload --> method setAsociacionesId is called.
But catch previous language value to change language.

Can you do this in #{inicio.inicio} (the action method) instead? By then the locale should be updated...

No.

I enter in browser :

http://localhost:8080/reservas/inicio.seam?asociacionesId=17

When change language page is refresh.

I don't call action "inicio" yet.

My only other is idea is to use immediate="true" on the locale selector.

If you can simplify this example a bit, removing the irrelevant details, it would be easier for people to understand exactly what you are trying to do.

It is simplified. There aren't irrelevant details.

If I change language with localeSelector, the locale change it after call action setParameters.

In this setParameters locale language is the previus language before I change with localeSelector.

If use immediate="true" in h:selectOneMenu --> Do same thing !!!
If use immediate="true" in h:commandButton --> Do nothing !!
