Re: Event bubbling - how to implement a top level catch-all target
Thiago, Actually, an error page is not what I want. I want to implement a message center (I call it switchboard) that distributes events and takes care of cross-component zone updates. I have a test version up in a project and I wonder why Tapestry does not support this kind of loose event handling where components register themselves for zone refreshes or method calls that are related to events. I find that essential to implement i.e. a global refresh zone strategy where a login component triggers a 'logged in' event and where other components subscribe to such an event because they have a zone that needs to refresh to display a different price. It would also provide a much looser connection between two less related components. I need to polish this a bit and are willing to commit this to the community as plug-in to tapestry because I find it very generic and essential. It's a natural extension to event-bubbling that otherwise only provides a one-way (up in this case) communication. /Andreas Pardeike On 28 sep 2009, at 16.27, Thiago H. de Paula Figueiredo wrote: Em Mon, 28 Sep 2009 10:41:35 -0300, Cordenier Christophe christophe.corden...@atosorigin.com escreveu: Hi Hi!

Re: How to create dynamic contributeXxx method ?
Thanks to my colleague,
I have implemented a simple and clean solution in the module class of my
component library which hold the whole configuration. Doing something like
this :
public static void contributeComponentClassResolver(
ConfigurationLibraryMapping configuration,
MyConfigurationService conf) {
// Add modules from configuration
for (LibraryMapping mapping : conf.getLibraryMappings()) {
configuration.add(mapping);
}
}
MyConfigurationService is marked as @EagerLoad.
Now the user of my library has only one entry point for the configuration of
module related informations.

Writing components in T5 is very simple. A good source of examples is
http://jumpstart.doublenegative.com.au:8080/jumpstart/.
In your case, you need to pull HTML from an external source. For this, I
recommend Apache HttpClient. Once you have the needed HTML in a String,
you'll need to write it to the output. This is done using a MarkupWriter.
This is a component I use in my projects. Look at it to see how you can
use a MarkupWriter. You'll need to use MarkupWriter.writeRaw() instead of
write(), as the latter encodes the strings ( into lt;, etc).

then override the property in the template just to output the value

Page alias Guice integration
Hi.
I am fairly new to Tapestry 5 and I have a few questions.
* Is there a way to declare a pagename alias for the URL generation e.g.
article for ArticlePage class or do I need to to do URL rewriting like
described here :
http://tapestry.apache.org/tapestry5.1/guide/url-rewriting.html
I'd like to keep Page-suffixes for my Page class names, but I don't want
to see them in the URLs. Without the Page-suffix there would be
simplename clashes with domain types.
* What is the preferred way to do Tapestry / Guice integration. While
the Tapestry IoC seems quite powerful, I got used to Guice and would
like to continue using it in my Tapestry projects.
I managed to wire up something like this which pulls
ImplementedBy-annotated services from a Guice module. Have you been
successful with something more general?
private static Injector injector = Guice.createInjector(new
BlogModule());
public static void
contributeMasterObjectProvider(OrderedConfigurationObjectProvider
configuration) {
configuration.add(Guice, new ObjectProvider() {
@SuppressWarnings(unchecked)
@Override
public T T provide(ClassT objectType, AnnotationProvider
annotationProvider, ObjectLocator locator) {
ImplementedBy implementedBy =
objectType.getAnnotation(ImplementedBy.class);
if (implementedBy != null){
return (T) injector.getInstance(implementedBy.value());
} else {
return null;
}
}
});
}
Best regards,
Timo.

Your service must have the perthread scope. A new instance will be created for each request, as each one is served by one thread. More details at http://tapestry.apache.org/tapestry5.1/tapestry-ioc/service.html , section Defining Service Scope. Great! I missed that part of the docs. Unfortunately, I get a problem with the component render cycle. Right now, in my test case, a component registers with the service within the afterRender() phase and this will trigger the creation of my per-thread service. So far, so good. Now, when I click on one of my test ajax action links, my custom component event handler filter routes the event to my service but since this is a new request, it already has been freed and will be created again. How can I make sure that information from component construction time will survive so it can be used when the ajax event is processed? /Andreas - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Page alias Guice integration
Switching is hopefully not the issue, but if my organization uses Guice by fiat, but wants to use a Tapestry application, a tapestry- guice integration would be nice, since it would be major surgery (with a low patient survival rate) to rip out t5-ioc and replace it with Guice. :) Christian.

Re: Bean editor model for User already contains a property model for property 'account'
If I tried to delete the account property first (e.g. exclude(account). Is
this correct?), then adding using model.add(account). The error becomes

Now it looks like the problem is because account is a read only field
(because I remove setAccount(String) method). Is there any chance to let it
automatically call e.g. constructor such as new User(account, name, ...)
(Though I think it is unlikely) ?
The bean model source used to create BeanModel is as below:
public BeanModel createBeanModel(Class clazz, String lang, String
country){
if(null == this.beanModelSource) throw new
NullPointerException(No
BeanModelSource configured!);
if(null == cache.get(BeanModel.class)){
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
URL url =
loader.getResource(messages_en_US.properties);
String path = url.getPath();
BeanModel model = null;
try{
ResourceBundle bundle = new
PropertyResourceBundle(new
FileInputStream(path));
model = beanModelSource.create( clazz, true,
new MessagesImpl(new
Locale(lang, country), bundle) );
//
}catch(IOException ioe){
ioe.printStackTrace();
}
cache.put(BeanModel.class, model);
}
return (BeanModel)cache.get(BeanModel.class);
}
Thanks for the help.

Have you tried to delete the property from the model before adding it?
By the way, what BeanModelSource method are you using?

amazing, i did not know that we can configure manually until reading that link: apestry.hibernate.default-configuration is there a short sample that how this can be be used?

Re: Bean editor model for User already contains a property model for property 'account'
The reason to remove the setter method (setAccount(String)) is because the filed `account' is originally purposed to be created once only when e.g. user registers. Therefore, the account field would not be changed/ edited after User object created. But it looks like BeanModel can not add e.g. account value using non default constructor, setter method (setAccount(String)) seemingly is unavoidable. Thanks for your help. I really appreciate it.

Re: Bean editor model for User already contains a property model for property 'account'
I didn't read the entire thread, but if this particular field has no setter you can add a synthetic property with model.add(account, null) and then provide a proper block override as outlined in the guide under Property Editor Overrides: http://tapestry.apache.org/tapestry5.1/guide/beaneditform.html On Wed, 30 Sep 2009 03:27:09 +0200, neo anderson javadeveloper...@yahoo.co.uk wrote: The reason to remove the setter method (setAccount(String)) is because the filed `account' is originally purposed to be created once only when e.g. user registers.

Accessing T4 State Objects in Spring Bean
Hi, Is it possible to access/inject tapestry4 state objects in spring bean. Actually i have a class extending AbstractRoutingDataSource to return datasource to use dynamcially. The datasource name depends upon user information stored in session. So how can i access tapestry state object or httpsession in my custom class. I beleive reverse of it is possible i.e. injecting spring bean in custom state objects howeever not sure if we can inject state objects in spring bean.
