Problem with locale

[Simplicity]

Hello everybody,

Excuse my poor english, I'm a french guy so I don't speak english very well ...

Ok ... I'm working under Netbeans 6.9.1, J2EE6, Mac OS X Snow Leopard, and tryin Primefaces 2.2-M1, the latest in download section from official website.

I have a problem when trying to switch locale with p:commandButton, ajax to false which reload my page.

I have some panels, two beans, and fr and en file properties.

The problem is that at the first time of submission, traduction is only applied where LocaleBean is present in XHTML. But if I click twice, that's ok, all msgs are translated ...

Do somebody know this issue ? It may/must come from me, but I don't undestand that behaviour. If somebody can help me ... Thanks.

Hi,

I had the same problem (like so many others) - it took me hours of googeling to find a solution (posted by Marty Hall) -> you have to additionally execute the code FacesContext.getCurrentInstance().getViewRoot().setLocale(xxxxx) after changeing the local in your bean. For example:

I'm using icons instead of a dropdown ->

Code: Select all

	<p:commandLink action="#{localeHandler.setAktuelleLocaleDE}" ajax="false" >     
	     	<p:graphicImage value="./resources/images/flags/de.gif" />  
	</p:commandLink>

Code: Select all

public void setAktuelleLocaleDE() {
    	setAktuelleLocale("de");
   	FacesContext.getCurrentInstance().getViewRoot().setLocale(getAktuelleLokale());
}

I hope that helps.

regards
Thomas

that should help, i've encountered same problem once and use same solution

Many thanks to you. That works.

Here is the simplified LocaleBean.java code.
