Hi!
Well, I could make it work... (I removed some verifications code
from the snippet blow to make it simpler to read):
public WOActionResults logoutAction() {
String language = (String)request().formValueForKey
("language");
changeLanguage(language);
WOComponent result = pageWithName("LogoutComponent");
Session theSession = (Session)result.context().session();
theSession.changeLanguage(language);
return result;
}
The strange thing is that I have to call changeLanguage in the
DA, and in the session... if I call only in the Session, I have the
reverse effect, that is, I get the LogoutComponent in english and
everything else in the desired language.
Why does this happen?
I'm not sure. It may be because you are using result.context
().session() to get to the session rather than just session().
LogoutComponent may not see the session.
I'd change the method to be:
public WOActionResults logoutAction() {
String language = (String)request().formValueForKey
("language");
session().changeLanguage(language);
return pageWithName("LogoutComponent");
}

Hi!
We have an application where the preferred user language is
stored in his account. So, he may see the application in English,
but as soon as he logs-in, the app switches to the language he
choose before. We do this by removing his language from the
session language list, and adding it again as the first one.
I'm implementing Logout now. To implement Logout, I have used
code from Practical WebObjects book:
public WOComponent logout() {
NSMutableDictionary arguments = new NSMutableDictionary();
arguments.setObjectForKey(Boolean.FALSE, "wosid");
session().terminate();
WORedirect mainPage = (WORedirect) pageWithName
("WORedirect");
mainPage.setUrl(context().directActionURLForActionNamed
("logout", arguments));
return mainPage;
}
When using this, it's obvious that, whatever the language was
before, the Logout page will appear in english. So, I did a small
modification:
public WOComponent logout() {
NSMutableDictionary arguments = new NSMutableDictionary();
arguments.setObjectForKey(Boolean.FALSE, "wosid");
arguments.setObjectForKey(session().languages
().objectAtIndex(0), "language");
session().terminate();
WORedirect mainPage = (WORedirect) pageWithName
("WORedirect");
mainPage.setUrl(context().directActionURLForActionNamed
("logout", arguments));
return mainPage;
}
And, in DirectAction, I tried this:
public WOActionResults logoutAction() {
String language = (String)request().formValueForKey
("language");
changeLanguage(language);
return pageWithName("LogoutComponent");
}
public void changeLanguage(String newLanguage) {
NSMutableArray languagesArray = new NSMutableArray
(this.languages());
languagesArray.removeObject(newLanguage);
languagesArray.insertObjectAtIndex(newLanguage,0);
this.setLanguages(languagesArray);
}
This almost works, but I'm having a problem... the
"LogoutComponent" itself appears in the correct language, but all
the sub-components it includes appear in English. I suspect this
happens because they have WOHyperlinks, so a new session is
created somewhere between by return pageWithName and the page
actually gets sent to the browser. Probably, the other
subcomponents are getting the language from the Session (which, at
that point, i cannot control) and not from the Direct Action.
As the session does not exist during the execution of my
logoutAction() method, I cannot change it's languages array. Is
there any way to solve this? Maybe forcing the creation of a
session in the logoutAction() method, but I could not find out how
to do it.
