Re: T5 : Expanding Messages Catalog for localization from arbitrary source
It has been a while since I worked with that code, so I don't remember
the exact reason. But when customizing some parts of tapestry it seems
that ordinary injects don't work. We did manual injects, by providing
getters and setters and doing this in the AppModule:
// Method for instantiating and configuring the custom messages
public static CommonsMessagesSource buildCommonsMessagesSource(
final ApplicationStateManager asm)
{
CommonsMessagesSource messagesSource = new
CommonsMessagesSource();
messagesSource.setApplicationStateManager(asm);
return messagesSource;
}
You can do the same with RequestGlobals.

Same problem with RequestGlobals. Comes up as null when I inject it.
Haven't tried the ApplicationStateManager yet, but in my head, the suggested
code sounds like the equivalent of the @Application state annotation, which
I already tried. Am I wrong?

Ok, thanks, I'll try that! I already tried the following in my class that
extends AbstractMessages:
@Inject
private HttpServletRequest request;
@ApplicationState
private User user;
Which didn't work, both were null. But what your saying is that these
objects are not possible to inject in this scope, but RequestGlobals is, so
the following will work?
@Inject
private RequestGlobals requestGlobals

Hi Inge,
glad to have been able to help you!
For your current problem, I can see two immediate solutions.
1. Store your user object as an ASO and inject ApplicationStateManager
into your Messages implementation. Get the user object instance by calling
applicationStateManager.get(UserObject.class).
2. Inject RequestGlobals in your Messages implementation. Then you can get
the request by calling requestGlobals.getHTTPServletRequest().
I hope this helps

Hi, Hannes!
I tried your implementation, and it worked right away, I just returned
the
value TESTING TESTING from my DbMessages class that extends Abstract
Messages.
But, what I need is for the valueForKey(String key) method to be aware of
the languageId/customerId of the currently logged in user. In all my
other
pages, I get this through injecting the request and getting my user
object
from HttpSession. Alternatively this can be moved to an ASO, but I
haven't
taken the time to do that yet.
I've tried injecting HttpServletRequest and ApplicationState on all the
classes listed in the implementation from Hannes, but none of them work
(only null values). How can I make information from the current user
session
available to my AbstractMessages implementation?

I tried the route with the Decorator once, and ended up having to write
some
java-code into the interceptor via the BodyBuilder 'twas not nice.
Your example worked great, i only had to pass some more Services
(AssetSource to get the URLs, my ProjectContextProvider to get the
ResourceBundles for my text) into the build-Method in AppModule, then i
could return the value for a Message-Key from the bundles, or if not
existant, from the fallbackMessages.

Hi,
I'd like to extend the Hash-Table containing the message-keys and
message-values used in my app. The app_en.properties provides the basic
global localization data, but I need even more data, which is spead about
in
other .properties-files or even in a Database. What I'd like to do would
be
to read in the data somewhere, and pass it on to the Messages(or
ResourceBundle) somehow, so when I @Inject the Messages into a

available at a root level.
Thanks for any help or pointers,
