Hello again
I still have an issue with localizating an testApp (as this app must
help me to master that subject ;-) it's a bit normal, isn't it ?)
Firstly let me say that i resolved the precedent issue by following
Chuc advice and by removing the Dictionaries definition from the
Session Constructor. I placed them outter.
So now when i test the app on Safari, it works great so that when i
change the default language of my system, the WOApp display the
corresponding localized Main Component. I added some print out in the
code in order to control the differents variables as you can see
below… So what's wrong will you say ?
Heck ! What's working in Safari don't work in Camino, and i didn't
test in Firefox.
Here is what i got on Camino :
Application: LocalizationApp
Error: java.lang.IllegalArgumentException: Attempt to insert null
into an com.webobjects.foundation.NSMutableArray.

Here is the quite bit simplified session.java code :

}
return aCode;
}
protected NSArray browserLanguages() {
NSMutableArray browserLanguages = new NSMutableArray();
if (context().request() != null) {
// So many different way to specify the accepted languages !
// Each adaptor has their own…
String aHeader = context().request().headerForKey("accept-language");
// Visualisation du Header
System.out.println(aHeader + " header");
if ((aHeader == null) || aHeader.equals("")) {
aHeader = context().request().headerForKey("Accept-Language");
// Visualisation du Header
System.out.println(aHeader + " header");
}
else if ((aHeader == null) || aHeader.equals("")) {
aHeader = context().request().headerForKey("HTTP_ACCEPT_LANGUAGE");
// Visualisation du Header
System.out.println(aHeader + " header");
}
String aBrowserCode = "";
java.util.Enumeration anEnumaration = browserLanguagePreferences
(aHeader).objectEnumerator();
while (anEnumaration.hasMoreElements()) {
aBrowserCode = (String)anEnumaration.nextElement();
System.out.println(aBrowserCode);
String languageName = (String)
languageCodeToLanguageName.objectForKey(languageCode(aBrowserCode));
// Verification 2
System.out.println(languageName + "_verif2");
browserLanguages.addObject(languageName);
// Verification 3
System.out.println(browserLanguages + "_verif3");
}
}
// Verification 4
System.out.println(browserLanguages + "_verif4");
return browserLanguages;
}
}
When i built it, i have got that for the several "System.out.println"
in the Run Log :
fr
French_verif2
("French")_verif3
("French")_verif4
Hello World
fr header
fr
French_verif2
("French")_verif3
("French")_verif4
Any clue to help me understand what's wrong with this code ?
Thanks.
Regards.
GM
