I'm gonna say clean your project and your ERExtensions framework, because on
line 157 of ERXSortOrder, I see
public Object width() {
return hasBinding("width") ? valueForBinding("width") : "9";
}
The error message is wrong. In fact, why is it reading
er.extensions.ERXSortOrder. That should be
er.extensions.components.ERXSortOrder unless you are using an ancient copy of
ERExtensions.

Getting strange KVC error concerning width and ERXSortOrder

Re: Localization problem, hello world too [solved]
Hmm, beyond that, I'm not really sure. Maybe someone who does session-less WO
apps has better advice.
Since writing that bit of info, I've accepted that attempting to use WO without
sessions is a practice in masochism. You lose all the real power of WO without
sessions. No component actions, no D2W, no Wonder Ajax, etc. All the best
parts of WO depend on a session, and in your case, you're already setting a
cookie. Ask yourself, "What difference would it make to set a session cookie
instead of (or in addition to) a language cookie?" Is that going to be worth
the pain of hand crafting pages, battling accidental session creation, and
managing page state entirely through DAs and cookies?
Naturally, those questions are rhetorical. Since I don't know what exactly
you're trying to accomplish, I'm certainly not saying what you're doing is
somehow wrong. I'm just afraid this little exercise in page state management
is only the tip of the iceberg if you plan on doing much without a session.

Nice patch :-) Oh, and for the record, what I was saying earlier about
needing to return something from session languages() is complete
garbage... I see you've already taken care of that in ERXSession's
setLanguage(). The problem here was my test app was returning null from
the updateLanguage() action instead of a page. [Are you listening to this
Mike? :-) ] I think this must be different from Mike and Chuck's debate
though, because even returning context().page() causes the contents of the
current page object to be re-rendered instead of refreshing the localized
component. I actually needed to do
public WOActionResults updateLang() {
return
WOApplication.application().pageWithName(context().page().name(),
context());
}
to get the right localized page component when changing languages.
Perhaps there's another way to invalidate the page and cause the whole
thing to refresh, but I'm satisfied with that for now...

Re: Localization problem, hello world too [solved]
Hi Ramsey,
my default language is English. In my performActionNamed method I am already
doing this:
String lang = request().cookieValueForKey("language");
NSArray languages = null;
if (lang == null) {
languages = request().browserLanguages();
} else {
languages = new NSArray(lang, "English");
}
ERXLocalizer.setCurrentLocalizer(ERXLocalizer.localizerForLanguages(languages));
but when I invoke pageWithName the current localizer is ignored.

DivaLook ?
Hello - I launched my new WonderD2W application and it came up like a charm. Now I want to get move my Look to the "new" CSS world of DivaLook. However, I can't seem to get it configured properly to work. No matter what I seem to do, I keep getting various Ajax errors? Now I configured my project to have the WonderAjax frameworks so I now don't know what I am missing. I think the DivaLook pages on the WikiPedia need a very simple how to make your new D2W app use Diva. What are the frameworks necessary and what are the rules. Anyway have success with DivaLook? Oh, and what is DivaLookLite? Thanks and Merry Christmas James Cicenia ___ Do not post admin requests to the list. They will be ignored.

German is your default? Did you try
http://wiki.objectstyle.org/confluence/display/WO/Web+Applications-Development-Localization+and+Internationalization
Second paragraph from the bottom (under "Direct Actions"). Instead of just
looking at the browserLanguages(), you could check for the cookie value first.

Re: Localization problem, hello world too [solved]
Hi list,
I have the same problem as described in this thread. I have an app that uses
only direct actions (no sessions) but stores the current language in a cookie.
By default I check for that language setting and set the current ERXLocalizer
accordingly. But when calling pageWithName I get every time the German
component (there is a German and an English component) even if I set the
localizer to English.
The setting er.extensions.ERXApplication.fixCachingEnabled=false as mentioned
by Ramsey didn't show any effect and digging inside the WOContext source I
found the method _languages() that should return the language(s) to be used:
If there is no session that method returns a _languagesAction array if non-null
but this var and its setter are private so I don't see how to change its value.
If it is null, which is its default value, then the browser languages are
returned. I think there should be a check, if the localization is enabled in
the app and return the language of the current localizer instead, shouldn't it?
Any thoughts? I altered my ERXWOContext for now and could put a patch on jira.
Happy Christmas,
jw
