Newbie Question Loading localization Resources from Database
Hi,
could you please help me with the following problem:
I use wicket 1.3.0 beta 3 + java 1.4.2 + tomcat 5.5
I wrote a small page that has a <wicket:message key="helloWorld">
when running tomcat I get:
[Localizer] Tried to retrieve a localized string for a component that has
not yet been added to the page. This can sometimes lead to an invalid or no
localized resource returned. Make sure you are not calling
Component#getString() inside your Component's constructor. Offending
component: [Page class = com.ppa.ubs.lbs.pages.Login, id = 0, version = 7,
ajax = 0]
Then I wrote a DatabaseResourceLoader implementing IStringResourceLoader
public String loadStringResource(Class clazz, String key, Locale locale,
String style) {
//funny effect locale.getLanguage() --> Nullpointer Exception
//I have to call locale.clone().getLanguage(). Is that normal? ?????
... do some db lookup
}
Then I added some changeLocale-Links to the page constructor:
add( new Link("localeEN"){
public void onClick() {
getSession().setLocale(new Locale("en", "EN"));
}
});
add( new Link("localeDE"){
public void onClick() {
getSession().setLocale(new Locale("de", "DE"));
}
});
The problem: When I change the locale through the Links, the message still
remains the same. The locale passed to the DatabaseResourceLoader always is
DE (german).
Question: Can it be, that the Session-Locale is not used, because of the
Localizer-Problem? Which locale is used instead?
Is there a better way to get database-resource-strings?
Thanks for your help in advance
Best regards
Marcus

Hi Eleco,
I' sorry somehow the problem with the locale being null is solved. I cannot
reconstruct it.
But the problem with the locale passed to
IStringResourceLoader.loadStringResource(..) being DE remains.
I have the feeling that the SessionLocale is not used. I verified this by
putting a label on the page (contents: getLocale().toString().) and doing a
System.out.println("locale:" + locale.toString()); in the loadStringResouce
method.
I need to load the String resources from a database because the customer
wants to make changes to the text without re-deploying the war-file.
Do you need more infos? Thank you very much. I think wicket is a great
product, so far.
Best regards from germany

Hi I just found out that this issue should be fixed in wicket 1.3.0 beta 4
(wicket-issue 936). Where can I get that? Which is the current release, best
suited for a production environment?
Thanks!

So,
I looked at the sources of Localizer,
for "Tried to retrieve a localized string for a component that has not yet
been added to the page. " which is the warning i get.
In this case the Localizer calls loader.loadStringResource(component, key);
without passing a locale. That's why I always get the german text :-) Sorry!
But now how can I avoid this "component that has not yet been added to the
page." problem?
When I use a wicket:message tag, do I also have to add that message to the
page-tree in my Java class manually?
Thanks
Marcus

Hi Cristina,
thanks for your reply.
The problem is, that the session locale is changed, but somehow
there seems to be another locale present which is then passed to the
IStringResourceLoader.loadStringResource implementation.
Have you got any ideas?
Thanks a lot

If you're setting the Locale in your Session (probably a class that extends
WebSession) and then getting the Locale through the Session, the warning
about the Localizer doesn't mean, as far as I know, that the Session Locale
isn't being used. Otherwise, the default Locale, which is defined by your
browser settings, will be used.

I believe .properties files are a better way to get localized strings... Is
there any reason why you can't/shouldn't use them?
Hope this helps,
Cristina
