Ahhh!!
That was the missing part. Thank you so much, Hannes, I could never have
figured this out myself. I still don't fully understand the code I just
wrote :) I nice little bridge between tapestry and my custom messages system
though!

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

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.

Ok, thanks, I'll try that! I already tried the following in my class that

Which didn't work, both were null. But what your saying is that these

Hi
I have recently wondered about the same, and have now built something
that after much trial and error now works.
Basically, I have created a Messages implementation that wraps both a
tapestry Messages object and our own database messages. If a message is
not found in our database, the default Messages object is queried.
To get Tapestry to use my Messages implementation i had to decorate the
ComponentMessagesSource (and ValidationMessagesSource), since it is not
possible to replace the one in Tapestry. I think I read about decorating
services here:
http://tapestry.apache.org/tapestry5/tapestry-ioc/decorator.html and on
the mailing list.
My messages source service doesn't implement the ComponentMessagesSource
interface. I use an interception object for that. Hopefully you can
understand how it works from my example code below:
public class CommonsMessages extends AbstractMessages {
private Messages fallbackMessages;
protected String valueForKey(final key) {
... logic to get key from db, use fallbackMessages as fallback...
}
}
-
public class CommonsMessagesSource {
public Messages getMessages(Locale locale, Messages fallbackMessages)
{
... code that creates a CommonsMessages object, with
fallbackMessages ...
}
}
// This is the decorating class
public class CommonsComponentMessagesSourceInterceptor implements
ComponentMessagesSource {
private final CommonsMessagesSource service;
private final ComponentMessagesSource delegate;
public CommonsComponentMessagesSourceInterceptor
(CommonsMessagesSource service, ComponentMessagesSource delegate)
{
this.service = service;
this.delegate = delegate;
}
public Messages getMessages(ComponentModel componentModel, Locale
locale) {
return service.getMessages(locale,
delegate.getMessages(componentModel, locale));
}
// Not sure about how I should handle this one
public void addInvalidationListener(
InvalidationListener invalidationlistener) {
delegate.addInvalidationListener(invalidationlistener);
}
}
---
In AppModule.java:
// Method for instantiating and configuring the custom messages
source
public static CommonsMessagesSource buildCommonsMessagesSource()
{
CommonsMessagesSource messagesSource = new
CommonsMessagesSource();
return messagesSource;
}
// Method that decorates the default MessagesSource using the
interceptor class
@Match("ComponentMessagesSource")
public static ComponentMessagesSource decorateComponentMessagesSource
(Object delegate, CommonsMessagesSource service)
{
return new CommonsComponentMessagesSourceInterceptor(service,
(ComponentMessagesSource)delegate);
}
This is how I got it to work, there may be other ways ofcourse. There
might even be better ways :-)
Cheers,

Summary: How do I include additional localization-key/values-pairs in my

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
page/component or use the 'message:' binding, the extra localization is
available at a root level.
Thanks for any help or pointers,
Mike

Re: T5 : Expanding Messages Catalog for localization from arbitrary source
Thanks Hannes!
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.
