我想通過鏈接使用更改語言。當使用它工作正常。如果我使用並導航到另一個頁面（使用操作），它也可以使用。當然，我不想在更改語言時導航到另一個頁面。我的理解是，commandLink應該與commandButton類似。我嘗試了不同的方式（在互聯網上找到），但似乎可以讓它起作用。我在這裏錯過了什麼？JSF2：使用commandLink不能重新加載頁面作爲命令按鈕
另外，我應該補充說，我正在輸入方法（請參閱下面的printIt（）），因爲我在控制檯中看到了曲線顯示。
語言鏈接位於標題頁（header.xhtml）中。我正在使用包含header.xhtml和正文內容的模板（template.xhtml）。 template.xhtml中沒有任何表單。
此外，我正在使用JSF 2，richFaces和部署在tomcat 6上，但也嘗試在tomcat 7上。默認瀏覽器是IE9。
這裏是header.xhtml：
<ui:composition xmlns="http://www.w3.org/1999/xhtml"

這裏是我的template.xhml：

我的web.xml文件是（產生with richfaces archetype）：

我的臉，配置：
<?xml version="1.0"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"

最後我LocaleChanger是：
@ManagedBean
@SessionScoped
public class LocaleChanger implements Serializable, ActionListener {
private static final long serialVersionUID = 1L;
final Logger logger = LoggerFactory.getLogger(LocaleChanger.class);
public void setLocale(String locale1) {
FacesContext context = FacesContext.getCurrentInstance();
context.getViewRoot().setLocale(getLocaleFromString(locale1));
}
public Locale getLocale() {
return FacesContext.getCurrentInstance().getViewRoot().getLocale();
}
public String i18nAction() {
System.out.println("Hello JCL...");
FacesContext context = FacesContext.getCurrentInstance();
logger.info("i18nAction Locale={}", context.getViewRoot().getLocale().toString());
Locale lang = Locale.CANADA;
if (context.getViewRoot().getLocale() == lang) {
lang = Locale.CANADA_FRENCH;
}
context.getViewRoot().setLocale(lang);
return lang.toString();
}
private static Locale getLocaleFromString(String localeString) {
if (localeString == null) {
FacesContext context = FacesContext.getCurrentInstance();
context.getViewRoot().getLocale();
}
localeString = localeString.trim();
if (localeString.toLowerCase().equals("default")) {
return Locale.getDefault();
}
// Extract language
int languageIndex = localeString.indexOf('_');
String language = null;
if (languageIndex == -1) {
// No further "_" so is "{language}" only
return new Locale(localeString, "");
} else {
language = localeString.substring(0, languageIndex);
}
// Extract country
int countryIndex = localeString.indexOf('_', languageIndex + 1);
String country = null;
if (countryIndex == -1) {
// No further "_" so is "{language}_{country}"
country = localeString.substring(languageIndex + 1);
return new Locale(language, country);
} else {
// Assume all remaining is the variant so is
// "{language}_{country}_{variant}"
country = localeString.substring(languageIndex + 1, countryIndex);
String variant = localeString.substring(countryIndex + 1);
return new Locale(language, country, variant);
}
}
public void printIt(ActionEvent event){
System.out.println("This is an action JCL...");
i18nAction();
}
@Override
public void processAction(ActionEvent event) throws AbortProcessingException {
System.out.println("In process ActionEvent?");
i18nAction();
}
}

我走了也是同樣的問題。如果我使用與commandlink相同的動作而不是commandbutton，則不會發生任何事情。沒有調用bean（沒有構造函數調用或別的東西）。我認爲，該命令鏈接跳過了一些階段...：/如果我找不到任何解決方案，我將格式化命令按鈕在CSS像正常鏈接...：/ – Tobi 2012-04-04 19:52:18
